WTH? It's either HTC's fault or Microsofts'/WinMo.Kinda sad that a 1Ghz SnapDragon can't do it compared to the underclocked Acer Liquid.
So what? 720p playback is ONLY useful if you don't have to convert the files or if you want to play them on a TV.
No phone is able to play 720p video without conversion. So the only advantage would be to be able to play HD video via TV out. But the HD2 does not have TV out, so 720p playback would be absolutely useless on the HD2.
On the Acer , like on any other phone, you STILL have to convert the files. It will only play .mp4 video in 720p.
If you play them on the phone, then it doesn't matter whether you convert them to 720p or 480p, the screen is only 800x480 pixels. You have to convert them anyways.
And yes, it's HTC's fault, because they don't fully use the Snapdragon chipset. It has nothing to do with Windows Mobile. But it doesn't matter anyways unless the phone has TV out.
Maybe in a not so far, far away future, it will make sense to have 1080p (or even higher, who knows) capable mobile devices - as soon as they are intended to deliver that high resolution content to a really, really large display.
Watching 480 lines of resolution on a 4.3" screen comes close to watching a 1080p BluRay movie on a 50" TV set, no?
As of today, I am just happy with what HD2 delivers... and for the home cinema experience, I do prefer the "big" screen anyway.

Or via TV out!
But as the HD2 does not have TV out, 720p playback would be useless.
(because you'd not be ably to use files from your PC without conversion anyways)
Who says you cant play them with out conversion? I have never converted one file to play on my phone. So yes it would be useful. It its capable of doing it, why the hell cant it, there is not argument here.
It can do it, so it should be able to, simple as that.

720p works only with hardware acceleration. Hardware acceleration works only for videos converted to the right file format.
No phone currently supports 720p playback without conversion because conversion is needed in order to use the hardware acceleration that the (Snapdragon) chipset provides.
It doesn't matter whether you own an Acer Liquid, an HTC Bravo or an HTC HD2, none of them will play your 720p .avi files from your PC. You have to convert them first.
Conclusion: 720p playback without TV out is useless. Period.
I'm pretty sure HTC left out the HD playback support because they wanted to save money on developing/purchasing the necessary software/drivers. And that is a wise decision for a device without TV out, because 720p playback is useless when you still have to convert the files and have no TV out.
Heu HD2 is able to play 720p
The only bad thing is the non support of AC3 in coreplayer

That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft). There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration. But Qualcomm insists on charging too much for the intellectual property rights to run software that is optimised for its hardware; HTC is too mean-minded to pay Qualcomm's fees and too lazy to ship its own multi-format software player (compare with, say, Samsung, whose proprietary video player software is both hardware-accelerated and extremely flexible about formats); and Microsoft can't be arsed to make Pocket Media Player support a sufficient range of formats and codecs either.
One can even quite reasonably blame the authors of Coreplayer for not having yet launched a version capable of using NEON instructions for video acceleration (something that is in the public domain and not under Qualcomm's control). All in all it's a bloody waste.

I completely disagree. Plenty of video is only available in 720p format; even for stuff that is available in 720p and low-res versions, the low-res version is often so low-res that downscaling the HD version would look a lot better on a screen the size of the HD2. It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion, and use only one version of the fule on both the phone and a desktop PC. Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.
Shasarak,
you don't understand. You are making assumptions that are simply not true. Let me correct you:
That is only the case because of the stupidity and narrow-mindedness of HTC and Qualcomm (and, to a degree, Microsoft).

Wrong: It has NOTHING to do with Microsoft and HTC. Nothing. It is only because of the Qualcomm chipset, that only supports acceleration for certain video formats.
BUT this is not an 'issue' limited to Qualcomm! There is no phone chipset that supports hardware acceleration of different video formats!
There is no technical reason why an application shouldn't be able to handle a much wider range of codecs and still take full advantage of hardware acceleration.

I don't know about the reasons, but fact is that NO phone chipsets supports that acceleration. So there must be a reason.
Even IF Microsoft or HTC would develop/pay for the appropriate software, the phones would STILL not be able to play other file formats because the chipset simply doesn't support it.
And other chipsets (not from Qualcomm) don't support it either.
It would be enormously much more convenient if one could simply download and play the 720p version without having to spend hour after hour after hour on conversion,
Click to expand...

Sure, it would be more convenient.
BUT as I explained several times: It doesn't matter whether the phone supports 720p playback or not, because conversion is always necessary due to limitations of the chipset, which only supports acceleration for certail formats (which applies not only to Qualcomm chipsets, but to every other chipset as well).
Obviously this is not something you personally would find useful, but that doesn't mean you have to be such a dog-in-the-manger about it: the attitude of "I don't want to do it, therefore no one needs to or should be allowed to" is really rather narrow-minded.

Thsi is not my attitude.
PLEASE READ PROPERLY BEFORE YOU ATTACK PEOPLE.
I explained to you in detail why 720p playback ability does NOT mean that conversion is not necessary. Thus, your argument of "not having to convert the videos" is misplaced. As you can read in the article above, the Acer Liquid ONLY plays 720p video that has been converted. And this is the case with any other phone as well, because of the reasons I explained above.
I dont know much about playback in 720p on the HD2 yet, but
Damien123_666 has done loads of camera tweaks (very good by the looks of it) and if you notice, he is working on recording in 720p
im working on 720p, micro-modes, bmp files and also increased video quality so keep looking for updates daily
Click to expand...
Click to collapse
So theres obviously the potential
Damiens thread is about recording 720p video, not playing it. Afaik Snapdragon has the potential of recording 720p video.
Here it's true, HTC is to blame for not enabling it.
But what I was talking about is 720p playback.
This is only possible with hardware acceleration.
Hardware acceleration is only possible for certain formats.
This means: Even if your phone supports 720p playback, you still have to convert the files.
Shasarak said that 720p would be a benefit because we would not have to convert the files.
But that's not true.
Even if HTC would develop/purchase the necessary software, we would STILL have to convert the videos.
(like on the Liquid, see the linked post)
That means: The argument of "not having to convert the videos" is not applicable here, because it doesn't matter whether the phone supports 720p or not, the files must ALWAYS be converted.
This means: The only advantage of 720p would be playing back HD videos on a TV.
But our HD2 does not have TV out.
This means: 720p playback capability would not be useful for us, as we would still have to convert the files and we don't have TV out.
I hope that was clear enough now.
@Shasarak
You CAN blame HTC/Microsoft for not enabling 720p playback, that's true.
BUT even IF they would enable it, they could ONLY enable it for certain file formats. You CAN NOT blame them for not enabling 720p for all formats, because this is a hardware limitation that exists on all other phones as well, no matter what manufacturer or OS.
I think you will find that people were blaming HTC for not enabling support. No one was complaining about it being available on only certain formats.
If my phone is capable of something, then I would like it to be able to do it. Simple as that.
No, you got it wrong, too.
People are not only blaming HTC for not enabling 720p playback, they are also blaming HTC/MS for not enabling it for all formats, and that's nonsense because that is not HTC's or MS's fault but a hardware limitation.
Just because the hardware is capable doesn't mean you can expect the support. It also needs software and that adds additional developing costs!
If HTC would have enabled it, they would have had additional costs, which means the phone would have been more expensive for you.
You can only expect what you pay for. You paid NOT for 720p video support, because that was not advertised anywhere by HTC.
HTC made the desicion not to enable it in order to be able to sell the phone at lower price. You either respect that desicion or buy another phone. You can not expect anything that nobody promised to you.
And as explained before, due to the fact that conversion is ALWAYS needed, 720p support is useless without TV out. You should be happy that you didn't have to pay for a useless feature.
seed_al
WTF are you talking about? Convertion is always needed? The CPU will downscale the video on the fly to fit the screen. You don't seem to know much (just like the Zunehd does). Any CPU is capable of.playing any format as long as the software enables it. You don't seem to understand this. SnapDragon just like nVidia's Tegra APX (& iPhone 3GS) is capable of decoding 720p WMV/MP4/H.264 at a bitrate up to 14bit/s 29fps. Even a feking Pentium2 can do this but at something like 0.02fps. The fact is that the software/drivers on WinMo aren't provided on the HD2
@MasterTP
Wrong. Completely.
You're mixing up hardware and software decoding! Do some research.
Of course any CPU can play anything. But only with software decoding, no hardware acceleration!
Hardware acceleration is only possible for certain formats. You even said that yourself: Snapdragon is cabable of decoding H.264/MP4 with the right software. But nothing else. Same for Tegra, iPhone and all the others!
That means even IF HTC had enabled 720p support, we would still have to convert the videos. Exactly what I said above. So please, next time, think before you post, instead of mixing everything up.
You guys are mixing everything up! I really don't know how to explain it any clearer.
I'll try one last time:
Okay, first of all: You have to distinguish between software and hardware decoding.
Every CPU can decode anything via software with the right codecs. That's what programs like Coreplayer do.
BUT: Software decoding is slow. Much too slow for 720p HD video.
THUS: 720p playback is only possible with hardware decoding.
Snapdragon, Tegra etc. support hardware decoding of 720p video.
BUT: Only for certain formats and only with the right software.
THUS: If HTC would provide the software, we could play 720p video like the Acer Liquid.
BUT: We would still have to convert the video files! (same for Acer Liquid, iPhone etc.)
THUS: The 720p playback capability would not free us from having to convert the videos!
THUS: The only advantage would be the ability to play 720p video on a TV.
BUT: Our HD2 does not have TV out.
THUS: 720p playback capability would not help us at all. We would still have to convert the videos and we would still have no TV out.
Okay, I think this is as clear as it gets. Got it now?
This thread made me lol
Personally I want my phone's battery to get hot enough for use as a hotplate.
There isn't a technical reason not to un-enable this non-feature, so HTC are stupid and m$ is evil.
F.Y.I Macbooks can do this since 2006 so don't say I'm uninformed
seed_al said:

No, I'm afraid you're the one who is mixing things up. It is indeed the situation at the moment is that only certain video player applications can make use of hardware acceleration on the HD2, and that those applications are only capable of playing a limited range of video formats. You make the mistake of assuming that, because this is the case, there must be something about those video formats which makes it inherently easy to play them with hardware acceleration, while it is inherently not possible to play any other format that way.
That is not true. There is no technical reason why someone cannot make a video player app which can play back any video and take advantage of hardware acceleration while doing it; the reason this hasn't happened is because of a combination of money-grubbing, selfishiness and incompetence on the part of Qualcomm, HTC, Microsoft, and a few other companies too.
If either Qualcomm were to release full details of their hardware, or HTC were prepared to spend a little more money, someone would then be able to write a video player app which could play back as many formats as Coreplayer and use full hardware acceleration while doing it. Whether that theoretical application could play back 720p video smoothly is another question; but I wouldn't be surprised. Assuming it could, such an application would require no conversion of 720p material to play it.

well it DOSE can play 720P with htc album. but for baseline profile and only 15fps……OK? 720P is here will you use it？
I don't know what seed_al was talking about.
I can play 720p video on my Touch HD (not HD2), but the performance is terrible.
If CPU is powerful enough, and software can utilize the GPU, playing back 720p (.avi) smoothly on a phone is possible for sure.

Im talking about watching movies, playing games - i dont know what the reason its so slow but it is painfully slow. its bothering me a lot. it seems like older much cheaper phones can play video much better than our phones.
is it a hardware fault (no hope) or a software fault ?
its a software fault
if you update your phone to some custom roms the phone runs LOTS faster
anyways, my videos and some 3d games run pretty fast on my phone.
not java games cause those arent hardware supported
I have to say that I am pretty darn happy with video playback on this phone... its fast and doesnt lag... the sound is even in sync with the picture unlike some devices I have tried before... I have not played any graphics intensive games on this phone so far though...
a game like archibalds adventure cant even scroll properly. i mean it looks like it was taken out of the 80s.
Maybe it is because this phone has up to 5 times more pixels then previous phones you have owned?
whats the point in it having 5 times the pixels if it cant cope with them

What videos? Are these videos, by chance a chintzy 320x240? I've tried avi videos in standard DVD resolution, 720x480 and 640x480 and they are both choppy as hell. There are far too many apologists for the really lackluster video playback on this device. I realize it's a driver issue, but when rich multimedia playback is one of the selling points, I think it verges on false advertising when it can't play accepted video standards. Have HTC pony up the money to Qualcomm for the right drivers and I think the X1 and a number of other devices in their stable can really start to live up to their claims.
Yeah, I have to agree. 5X the pixels means nothing if the phone can't handle them
No problem for me with video...
-I recode vidéo in 800*480 with HTC Touch HD Video Converter
-I use Windows Media Player to watch video
rom im using
im using touch it xperience 3.5 but i've heard touch it 2.2 was faster
from now on if it has qualcom in the hardware spec im gonna avoid it like the plague!
I gotta admit, just when I start being happy with the Xperia video.....
I'll look over at some movie my wife is watching on the iphone and just shake my head. The Xperia is NOT impressive in the video dept. I can get video to play to ALMOST lag free and it looks pretty dang good. But c'mon already! With the hardware capabilities of this phone, video should look all around amazing.

I have converted some Chinese tv serial episodes using magic video converter and they came out great, not too sure of the res but by memory its around 640x480 to 720x480 as you comment... no lag and sound is better than I expected... I also have a movie or two that works just as well, again Chinese stuff (as I am learning Chinese I find this is an interesting way to help out with both reading (subtitles) and listening)... I am using coreplayer and have it in full screen mode when watching...
Oh and I am by no means an apologist... if it was crap I would say so, but its not... but then I dont expect my phone to act or have the same capacity as my laptop/pc.... its a phone and does what it says on the tin...
I dont get it. I have a stock ROM and my video is perfect. I downloaded an Ipod converted (m4v) version of Superbad and it looks and sounds amazing FULL screen btw). All i had to do was rename the file to mp4 and it works perfectly! Maybe there is something else going on with you guys phones. I also have Anchorman, SemiPro, and several others running perfectly. Besides TF3D, i dont have any other plug ins installed.
I also have no issues with video playback,
I am running Touch IT 2.2 which i am not willing to replace yet because the ROM is fast as hell and bug free. Just used the HD converter in the sticky on page 1 along with a few speed tweeks from the Mark a Clienti thread and POW!! full screen, top notch quality res and not a single lag or frame drop in sight.
I have noticed that a lot of people are having issues with various applications on their SE X1's but i dont seem to have had any issues at all. I started with the clean ROM and made sure i installed all of my required apps and tweaks in one go, making sure to reset after each install. After that i just sat back and watched it fly, maybe i'm just lucky

You might want to check out what the bitrates are on those videos. Your average avi video is about 1.3-1.4 gigabytes in size for your standard 1.75-2 hour movie. That comes to about 1,500 kbs. Anything significantly less than that and it looks kind of muddy when viewed on a regular sized TV screen. Ideally, you shouldn't even have to recode video you ripped yourself. In theory you should be able to rip once and play on all your appliances that are video capable using a standard codec with reasonable settings. An avi file 1.3 gigabytes in size for a 2 hour movie is entirely reasonable and I highly doubt that you can achieve that with the X1 in its current state. I've tried extensively and the only way you can make it play with any level of smoothness is by dramatically reducing the resolution or dropping the bitrate precipitously. You can't just drag an acceptable video from your computer onto this phone and expect it to play acceptably the way it is right now. As for the expectation that it's only a phone I say that the drivers are the only thing that prevent it from meeting the expectations. I'll bet the hardware is there, but HTC just feels like being cheap. Heck, there are phones debuting at MWC right now that do full motion 1080p playback of h.264 video. The X1, which isn't more than a few months old, can't smoothly play back a 640x480 1,500 kbs video. At $700 retail and their promise of a full-featured multi-media device that is scandalous. I dare anyone to say otherwise.

You sound much more knowledgable than me so I wont try to argue with you, but I have quite a few avi files that are around the 800mb size that play very well and are crisp and clear even on a bigger screen (my laptop is 15.4 and pc is 19inches), in fact I find it pretty rare to have an avi file over 900 Mb for a standard movie (up to 2hours I would guess is pretty standard)... As another poster a couple of posts back mentioned, I notice a few problems that people are having that I dont... thank goodness as with my level of understanding I would be hard pressed to now what it is I need to search for to fix the problem...

Seems like some people managed to play 1080p on iPhone 4.
SGS has almost the same CPU with better GPU and option for overclock.
What is the reason that is preventing us from playing 1080p? Not good enough app or something else?
1080p on a 4" screen? no thank you.
We just seems to be needing a good codec to play 1080p. So it should just be a software limitation unless the GPU is capped at 720p!

@Prankey,
I guess SGX 540 can play 1080p if SGX 535 can.
I'll make a wild guess here:
iOS has all the software needed for full hardware acceleration while Android don't.
How is this a development related question?
And I thought galaxy can play 1080 without problems (didnt try though, as its very stupid).
so iPhone display is 960 x 640 pixels?
1080P is 1920 x 1080 pixels
unless it can output HDMI, seems pretty pointless to me.
The screen resolution is 800x480 anyway so the extra resolution does not benefit you at all. It's just a minor convenience to avoid converting the video but you're wasting battery power to decode the video and a lot of space. 720p is enough of a battery and space waster.

You still have to convert the video though for these devices still cause h.264 codec support for mobile devices don't support all of what the codec can do. It's also wasted bit rate as well. It's better to have a lower resolution video with a decent bit rate then it is to have a video with a massive resolution but not enough of a bit rate to smooth out artifacts. this resolution race for videos on mobile phones is a tad stupid.
Rock player plays 1080p for me.
The Video I tried was a bit choppy though but acceptable.
(I guess about 15-18fps). I only tried one Video wich I accidentally loaded on my device.
As far as I now Rock player does not use any GPU acceleration though pretty impressive what this little CPU is capable of.
Definatly plays full hd better then my atom netbook.

Seems like some people managed to play 1080p on iPhone 4.
SGS has almost the same CPU with better GPU and option for overclock.
What is the reason that is preventing us from playing 1080p? Not good enough app or something else?

1/ there is no point, resolution-wise
2/ with iphone there is a VERY limited range of file formats you CAN actually play, so you will spend half your life converting to a format that apple can control. Most my 1080p movies are mkv format, a format that works on Galaxy S but not on iphone. All my SD movies are Divx and Xvid, again, not compatible with iphone.
Mark.
Well actually we can! Rockplayer can do it so please stop spamming this forum!
You apple fanboy

just ****ing stupid! 1080p on 800x480, wtf? even 720p is higher than the screen-resolution! also a movie in 1080p has ~10Gb which would almost fill my 16gb card. STUPID and completely SENSELESS!

well apparently the people with iphone4 are too rich and too <insert what you think here> to care about that.
they probably think they have super wireless and can stream a 1080p movie and watch it over the air

And why not? 802.11n is more than enough for that...
Anything that can be done on the iphone 4 can be done on the galaxy s, just needs the right software to be made.
The only difference between the iphone 4 and the GS is the software, the screen, and the galaxy s having one generation newer gpu
Anyway what's the point in this? sd cards have a 4gb filesize limit, 1080p would waste so much battery for no benefit over a 720p file
technical spec yes
real life usage, not so great
wireless N is what i use for my home teather, yes it "works" but load time is horrible, as well as the random cut offs, then waiting for the load time again.... it's a pain in the aussie
it's much more convenient to first copy the entire movie into the hard drive via wireless N, then watch it
but that defeats the entire purpose of streaming a movie
Any devs looking at the possibility to record movies in fullhd, 1080p ? I seem to remember I read somewhere that it should be capable of it.
Well if it is capable of recording in full-HD then why wouldn't Samsung themselves implement it so to make more sales?

Are we talking about the same company that decided to use rfs filesystem and use reserved memory thus limiting available ram... not to mention the weak wi-fi reception / gps issues.

Exactly my point, there could be a thousand of different reasons. But maybe our devs inhere are a bit sharper than Samsung themselves...
People have made mods that claim an extra 20 - 30 megabytes of RAM. When these are applied problems are noticed with 720p recording. Imagine the ram usage for 1080p. I don't think its worth the hassle.
1080p used in mobile phones do you think will be much better?
come on!
i dont think so...
Especially since the audio is still bollixed... if they fixed that first.

Dont think it need it.
First if hardware permit to record 1080p stream the 5megapixels chip wont manage to provide 1080p frames with a decent framerate.
then if it could the optics wont be able to resolve the resolution gain.compared with n8 nokia or iphone 4 720p output you can see what there s place for improvement in this way(sharpest optic and better sensibility)
but may our dev can work on compression level to keep more fine detail , sensibility management or faster autofocus without resolution change.
think this is the only reasonable improvement we could expect by software mod
Well, I have problems with 1080p playing, let alone recording.
Anyway, the hardware is 100% capable of 1080p recording and it would be really cool if some can mod it.

Hummingbird is capable of 1080p hardware decoding/encoding. It's equipped with hardware encoders/decoders. Both of them require decent amount of RAM reserved. I think that was the issue.
5mpix sensor is perfectly capable of delivering decent framerate @720p, why wouldn't it be capable of 1080p?
Resolution is enough, there might be bandwidth limiting factors between sensor-CPU.
Optics is perfectly capable of making quite sharp photos @5mpix, why wouldn't it be capable of shooting just 1920x1080?
There will be no software mod enabling 1080p recording, without hacking into hardware codecs/drivers.
Even if the framerate would go down to 15-20 fps, I would personally really like this feature. Some moments are best captured in highest resolution possible. An idea about the memory could be to allocate needed amount on demand, thereafter releasing it again?
Thanks for confirming that our Galaxy S is indeed hardware-wise capable of recording in 1920x1080.
Actually, why 1080p? It doesn't NEED to be 1080p. Why can't we add support for 800p (800lines vertical res) or even 960p.
We keep thinking about making the jump to 1080p, but is there any reason why would couldn't ramp up the resolution higher on the camera? Just because your TV expects 720p, doesn't mean computers do when playing it back...

800p and 960p are not common, so it would make things awkward. Can't play it on a 720p screen and not properly on a 720p screen.
BTW although noticable I don't think the difference between 1080p and 720p is that big. So I don't think anyone would really notice the difference between 720p and 960p and if so probably more as a placebo than a real difference.

I agree on the odd formats. However, going from 720p to 1080p is a significant improvement, especially if you have a large ( 46" + ) flat panal to view things on.
I would be very interested in this. And for everyone saying its not needed, this is a development forum. Many many many things that are done are "not needed" but still pretty cool. He asked if it could be done, lets stick to if it can, not if it should.

720 from 5 meg camera is already seriously pushing it, almost hack wise. Normally only 8 meg cameras should support it. And im not speaking about 1080...
The sensors usually can't deliver 30 fps at 1080p even if the hardware can encode it (which ive seen no tech specs of,just various "web claims" aka moot stuff)
It's not because its a 5MP sensor etc, its about how much data can go through the sensor after it's captured (that's before the CPU/DSP!!) You have very good 5MP 1080p cameras, because the sensors can handle it. They also cost more. I highly doubt the one in the SGS can handle much more than 720p at 30fps.
i'd rather have the image processing improved than 1080p, since 1080p (if it could be done that is) will be approx the same quality as 720p, use twice the space and need twice the power to decode on other systems.
in fact even the encoder can maybe be optimized. i'm not familiar with the hummingbird, but the OMAP's have TI's own such hardware codecs and while its proprietary you can implement your own codec accelerated by the DSP.
HummingBird's codec produce "very average" 720p H264 mainline (i believe?) at 10-12mbits (!)
Compare with x264 4mbit 720p H264 high profile quality for the same source, it blasts it away quality wise and is 2/2.5x smaller in file size. besides it has a zillion options depending if you want quality, latency etc.
bottom line, if a genius would accelerate x264 via the DSP it would be awesome.
I know the x264 team worked on the OMAP DSP with little success, mostly due to rather cryptic documentation
There are plenty of PC displays which AREN'T 1080P (only cheap ones). 1080p and 720p is optimal for TV's, but not computer displays. There are plenty of computer displays which are 1200 lines vertical resolution.
And I've found a difference between 720p and 1080p, but it's more obvious on larger displays which supports higher resolutions
I'd rather have slow-motion and a proper app that enables video editing/cutting/sound mixing just with Iphone 4.

I'm inclined to agree, theres room for improvement at 720p, its like the same logic as low end cameras and camera phones alike ramping up the pixel count doesn't directly mean better quality..
Plus the phone although it should be able to currently doesn't like playing back 1080p videos...
I'm not saying everyones going to want to watch 1080p on an 800 x 400 panel, just saying you might want to play back what you've just recorded to see how its come out..
so here's my issue. it seems the video player itself has issues displaying 1920x1080 video. 1280x720 works fine, same video. same bitrate, same everything. this seems crocked.
do we know of any workaround for getting a 1080p to work. i've heard of people pulling it off, but i've spent three hours on this and i really believe it to be the player. i've tried third party clients and they're about 5fps. it's irksome.
help plz?
You know we have two different video players right? We have video player, and we also have movie player or something else like that. Try it.

What do you expect to get from playing such large videos on the Cappy? I transcode mine to 720X480 in .mkv and they are simply stunning with zero playback issues. The Cappy supports the low end HD resolution of 1280X720, not the Blu-Ray rez of 1920X1080. And it supports that rez in shooting video so that it can be played back on a larger screen. There's no benefit to playing back videos that size on the device. Resize them, you won't notice any difference in picture quality and you'll save a ton of storage space.
I have 315 bluray movies half are 1080p other is 720p so half of my media is watchable on my cappy and my tab. I use Tversity to stream to my ps3 and everything but if there was away to make it only transcode 720p to mobile devices or have a player that will resize it for us that would be awesome.

May be more of a codec problem than anything else.
While I never put anything bigger than 720p on my phone (since 1080p has no appreciable visual increase in quality on the phone screen, but a MUCH larger file size), I definitely have played 1080p on my phone before. Hence why I think it may simply be that 1080p MKV w/ certain codecs might not work. Remember that media files *legally* downloaded from the internet will often have slight variations in the parameters used when converting to MKV w/ x264/VC1/etc codec. Hence just because 2 files are "720p x264" in a Matroska container doesn't mean they are actually identically encoded. And the Galaxy S can sometimes be a bit picky about what formats it "automagically" supports and which it doesn't.
And by the way, as you clearly noticed, the "Video Player" app in Android is the only one to use the GPU to accelerate video playback. Other apps might work, but they will run the CPU way harder, and give you worse battery life. Monitoring the "time_in_state" to see what the CPU is running at, I can play 720p x264/MKV files with the CPU at only 400 MHz. Obviously, sometimes the default player won't play what you want, but it's much better to use it if at all possible.

This is the main reason I stick with the built-in player. I was on a flight from Ft. Lauderdale to St. Louis to L.A. on Tuesday and I watched 3 movies of close to six hours total length. Landed in L.A. with 31% battery still remaining.
my reasons for wanting to play 1080p is irrelevant to the scenario, i'd just like to see it done.
i considered a codec issue shammy, but i extracted a 60second sample from my crank copy and left it in 1920x1080mkv and tried it. no dice. i handbraked it to 1920x1080mp4 no dice. i once again handbraked it to 1280x720mp4. worked fantastical without any change in any settings except res. hence why i think its a limitation on res rather than codec/bitrate.
i am just IRKED all around at this. time to hit the irc and start screaming at people until somebody gives me an answer huh lmfao

How do you lose quality by resizing for the device you'll be playing on? All those extra pixels of HD resolution on a 800X420 screen do not yield better quality, they just require more CPU/GPU to process and more storage space. Nothing is gained by playing HD-sized videos on the Cappy. Absolutely nothing.
I own a small HD video production company in L.A., but don't take my word for it.
I was talking about playing the same media file from my Ps3 on my tv. I'd rather not convert my 1080p files to 720 just for my hand held I'd rather have a better way to do all of it using the files I currently have. Tversity works good but not perfect for over 3G but when I had my iPhone it would play pretty good using airvideo over 3G but there has to be something to make it all work

It would be nice to be able to do this I suppose..but if you don't mind...Why ?
If you play it on any other thing but your phone..you will not really benefit from having it this way..and also..you won't really have enough storage to hold it to be able to watch a full featured film.
Until Samsung gets off their asses and fixes the issue with making the usb-hdmi cable you will never get the output capable of seeing any difference than what you can easily do right now at 720p...If you want to ***** about something...that is what I would ***** about..They had those cables available for 1 month..and not many was ever shipped out to the stores when they introduced the phone...I've e-mailed them every week since October and the only reply is they are working on it...so...I'm not holding my breath on seeing it anytime soon since they are working on the next line of phones already..

I was doing my best to not "*****" at you "other people". If I wanted to ***** i'd be obviously *****ing, not laughing about it. How about I send you my 12TB of video and you can convert it all into 480p, would that suffice for you? since you have such an issue with what I do with my device and provide absolutely no helpful solution, you do it! I sure hope you have couple dual 12core opterons sitting around, because it's gonna take you awhile. currently, encoding crank.mkv time remaining: 1h5m. now realistically i'd never convert my entire collection, just whatever video I want to watch at the time. but guess what? When i'm leaving or doing something I do not have an hour to wait. It's almost faster to download a 480p copy, you realize that right. converting while dealing with 1080p is not fast, nowhere near it. I find it unlikely you have any experience in the matter, i'm sure i've put more time and effort into this than your useless 30 second out of line response, so "chump" take the attitude and leave my thread please.

i started with 1920x1080 crank 60s sample gone through handbrake reducing it to about 6mb.
1920x1080 through
1282x726 do not play. at all. unknown file.
1280x720 and below play without issue, and play damn well.
the file is exactly the same codec and container, just resized. so i believe it to be an issue with the player.

Could it possibly be that your video is simply beyond what the player and/or the device is designed to handle? Square peg, round hole, I say. 1280x720 is indeed within the scope of the HD specification, so there is no fraud in saying the device can play HD content. It just can't play the high end of the HD spectrum. Live with it or get another device.
He's just trying to find away to not reconvert 3,000 hours of videos... if there was away for the computer to transcode to 720p to the device but leave it 1080p for the ps3 but not make 2 files for one video.... how hard is it to want that???

I understand that, but it's like complaining that his old tube TV won't display HD signals. Or that his DVD player won't play BD discs. It just wasn't designed to do it. For a device to transcode 1080p to 720p on the fly would require a lot more horsepower than what the Captivate has under the hood. Accept and move on.
First, I understand why you want this; it's a matter of convenience and I don't blame you.

It may be the same codec and container, but what is the bitrate? A lot more data may have to be pumped through the i/o system and larger frames are going to have to be resampled. I'm not saying it is impossible on the hardware, but it might be. I seriously doubt that it's just a matter of some bug, oversight, or intentional disabling of 1080p without good reason.
I'm not sure that how many people at here know this fact.
Tegra 2's H.264 decoding is waaaay worse than Hummingbird(Galaxy S)
It cannot run any HD H.264 video HP.
Source?
Tegra2 can decode 720p at AVC HP and 1080p at AVC MP with reasonable/usually bitrates at 30p.

allthough Tegra 2 would be up for the task (at 720p30 HP) as mentioned earlyer.

I think with VLC or RockPlayer you can probably see a difference
How does x264 perform?
I think its the same issue as Adam had with the video/audio desync. Its not a hardware limitation.
I don't get it. I've tried various videos and none of them work properly. However, the demo video files that were on the device (1080p) run perfectly. No frame-skipping at all.
Is there something I'm missing?
I was kind of baffled by this too.
Brilliant playback on the included 1080p files.
So i thought yay lets grab some 1080p trailers from youtube with tubemate.
But alass. not very smooth! Think its indeed the profile that does the trick. or in this case, doesnt.
Next thought. Ok rockplayer will help me out here!.
But i wasnt too impressed with rock on my galaxy s either!.
Loaded rock. but also very crappy. Which is when u think of it, pretty logical.
Why? No hardware support! Rock doesnt even remotely know what a tegra2 soc is. and in fact, NONE of all the video apps do.
So in stead of funky tegra2 hardware decoding, you get software playback.
Ive heard some rumors about nvidia developing an android video player for tegra but i dont know if this is true or not at all.
so unless someone makes a proper video playback app (which in my opinion is way over due already! no offence but theyre all crap if u ask me!) which supports hardware playback AND tegra2 soc, it wont improve very much.
My 2 cents
Ok some more info, apperently Tegra2 isnt very great with high profile encoded. baseline and main profiles should work. more testing to do. Also everything below 1080p high profile should kind of play properly. My eyes are on VLC for android and fingers crossed for them to bring tegra2 suppot and their own great codec sets
Check the Motorola Atrix forum, on XDA (sorry cant link from mobile app), they have basically given up on playing hd h264 files on tegra 2. Such a shame.

Yes indeed. It sucks ass. I have the same unit but then from T-Mobile Netherlands. Video included works like a charm (ofcourse) but own added videos look like they are in slowmotion. 720p, 1080p doesn't mattter same issue.
Extra added flaw? When your record video in Full HD it does not play back on Full HD TV's or BD players. I checked why and found that it actually records in 1920x1088p!!!! Yes 1088P people.
FOTA updates are also not working for the T-Mobile branded unit. Comes back with validation error.
Tegra 2 limitation
Some search on the internet revealed that Tegra 2 supports fully h.264 main profile, but for high profile, it is only 720p 6MB/s, which is then not suitable for a BD. Anyway, I don't have the intention to fill in my 32 GB of storage with just one movie...
Recording in 1088p instead of 1080p is a bit more annoying, you think there could be a solution for that?

I tried to play a mkv file yesterday with the build-in player which crashed my phone.

What kind of mkv did you try? 1080p?
I keep saying its a software issue causing all these troubles, i have a Adam and since the latest update i saw a improvement on the video playback.
Once we get proper support for mkv it will be awsome

Do you have a video of the adam playing back mkv?
You can search in the thread @ my sig for " Notion Ink Adam Qi Vs Motorola Xoom by Inspiron41 "
I can add that any file that i have MKV to be played has to have the extension changed to AVI and only QQPlayer can run them, if the sound quality is high more than 2 channels the fps rate will be low this happens with either 720p or 1080p. But if i try to run a MP4 file with 1080p it runs very smooth with audio and video sync, so for me its a issue with decoding of MKV.
Oh and the Adam is running froyo no multiprocessor support neither the video apps do.
