iPhone 4 now plays 1080p videos easily, then why Galaxy S can't

http://blog.gsmarena.com/iphone-4-now-plays-1080p-videos-easily-does-some-xviddivx-magic-too/
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!

I would never watch 1080p on 4'' screen (even though some people would)
I'm just curios about the hardware.
@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.

1080p isn't even listed as a file which can be played. You can't even upload it via iTunes, so there is no official hardware acceleration built in for 1080p.

I guess it is a development question, because it may be related with codecs, drivers, etc.
But no, it can't. I have tried it, even though I'm not about to watch full HD on my SGS

We can use microUSB to HDMI and we have DLNA. So it would be useful to us. Anyway, as I've already said my interest is about hardware capabilities not watching full HD on my phone.

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.

agree it's simply over kill
all the extra processing is wasted on a 4" screen
actually iphone4 is only 3.5" not even 4"
720p is more than enough on the 4"

I wasn't talking about hardware accelerated 1080p playback. I was talking about how everything in iOS is adapted to support as much of the hardware features as possible, while Android is not adapted to support the SGS hardware in any other way than Samsung just tossing in (semi)working drivers.

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

Can the Nook Color play videos encoded in 1024x600 and 2,000 kbits rate?

Now that I heard you can put Honeycomb 3.0 on the Nook Color, I am thinking of getting it today at B&N.
However, I will be using the device mainly for watching movies and I love to convert movies. I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality.
My question is: Can it play .avi files with 1024x600 resolution and 2,000 kbits rate super smooth on Honeycomb?

Looking at the Honeycomb thread:
Doesn't work:
-Sound (sadly! Despite my efforts the last hours I didn't get it working properly yet)
-DSP e.g. no hardware video decoding

So that would seem to be a significant barrier to your plan ;-)!
In the basic 2.1, the recommendation is for MP4 (H.264) at 1,100 kbps. I recently watched Inception at that setting and it was perfect for the Nook Color.
Check out this thread regarding Handbrake settings for the Nook Color: http://forum.xda-developers.com/showthread.php?t=894165

for any kind of hi-res content, you'll want to use hardware accelerated playback. Unfortunately, the chip in the nook only supports a certain video codec and resolution. h.264 basic profile and a max of 800x480. 1100 kbps looks pretty good.
Any other codec or higher resolution will rely on the software renderer, and it will be very choppy.
I created a nook color preset for handbrake you might find helpful. It will convert your 720p movies to the highest quality the nook supports.

You guys just burst my bubble. If the max resolution that it can play is only 800x480, then I guess I will not be buying the Nook Color. Even my HD2 can play mpg4 file that is encoded in 800x480 with 2,000 kbps smooth as butter without problem. If the NC cannot play 1024x600 with 2,000 kbps, then what is the use?
I guess I will have to wait for the Xoom to come out.

800x480 looks great. The nook scales it up to 1024x600, and the pixel density is high enough that you see no pixels. It looks very smooth.

You do realize that the hd2 has a 1ghz snapdragon processor. While we only have an 800mhz stock that can be overclocked to something equivalent. Why would you expect it to do better than the hd2? I would say they would be the same. But if the difference is worth the extra $350 premium then go for it. 854x480 at 1100kbps looks amazing on the nook.

The biggest dissapointment with my Nook is the video playback. Its not horrendous on eclair, but I have absolutely no luck with it on these froyo builds. Probably going to go back to 2.1 soon just so I can at least view some videos again.

I never thought of owning the Nook Color until I heard about being able to put Honeycomb on it. I prematurely got excited and thought that it can do good video playback since my HD2 is excellent at playing 800x480 file at 2,000 kbps encoding. I knew that it can be overclocked to become more powerful. If it can only do 854x480 at 1100 kbps then it is a big disappointment. Beauty is in the eye of the beholder. If 854x480 at 1100 kbps looks good to you, it may not look good to me because of possible pixelation. I want a device that can play full screen resolution with high bit rate. I know that it would require bigger memory card/bigger storage space and slightly consume more power but that is what I am willing to sacrifice.
Well, I guess I have to get either the Xoom or the G-Slate. I don't mind paying extra for it. Just put in some extra work time and I will get a device that I will be happy with.
I love gadgets and love to tinker with them and that is why I enjoy putting all kinds of available OS onto my HD2. I was just about buy the NC just to tinker with it but I guess I will wait until the great people at XDA can somehow get hardware video acceleration on the NC to be able to play videos at higher settings.
Thanks for all the info about the nook's video capability. It was very informative.

DSP support?
What are the chance the DSP will get supported in Froyo/Honeycomb?
So even with hardware acceleration we only get [email protected]

Video quality
Any idea if this would work better if the nook was oc'd to 1.1, I guess once the dsp is fixed maybe that and a 1.1 cpu will work.

While i do lov to play 720p videos on my captivate (its screens is 800x480) it is down scaling those videos... the main reason i do 720p is because thats what tubemate will let me download them as and still work..
That being said he 480p that the NC can so is still a very good picture.. Normal CTR TV's are only 480i dvd's are at 480p and they still look good on my 42" 1080p tv.. not as good as blu-ray but still good.. and thats stretched to 42" were talking about 7"
1080p 42in= 52.45 DPI
1680x1050 20in monitor= 99.06 DPI
NC running 800x480 at 7inch= 133.28 DPI
NC running 1024x600 at 7inch= 169.55 DPI
Now.. looking at those numbers.. so you REALLY need to run at 1024x600? even at the 800x480 your getting less pixelation then you do on a 42inch 1080p tv.. yes the NC is held ALOT closer.. but even so.. its still giving you DVD quiality picture in your hand on a 7inch screen..

The video playback is definitely disappointing. It sucks not being able to just download a video and just watch it.

I'm getting a bit lost from the conflicting opinions. I'm a lazy and VERY not fussy video viewer. My main use of my NC is to watch videos that were originally made for an iPhone.
Bottom line... Now that sound is working in honeycomb to the NC. am I going to be able to watch my simple iphone type videos on my NC if I take it up to honeycomb? Remember. I'm not at all fussy about quality as long as it isn't too terribly jerky.

From what i understand (and thats not much =) currently honeycomb still has NO hardware acceleration for video.. nither does froyo so the best video playing on a NC you can get is currently running a rooted stock rom.. encoded at 800x480 or below.. the iphone 3gs and older all have a screen size of 480x320 so they SHOULD work as long as they were encoded properly (right codec and such)

Although I understand the excitement, this seems like a very premature discussion. Despite the repeated statement that honeycomb is available on the NC, out is in fact not. What you are seeing is actually an SDK build. Software Developers Kit. For development. And the first SDK at that. You are essentially seeing an emulator running on the nook screen.
Before everyone goes nuts I know that is not technically correct, but it is as correct as saying we are running full honeycomb.
After an AOSP build is released we will see a more functional version and eventually probably see better integration with the video hardware. And for my final rain on this parade...I am a professional video content creator. And if you think you are able to see the difference between DVD quality and 2100 stream HD on a 4.3 inch screen, you are mistaken. Or have vision above that of mortal men.
For the record I owned an HD2, now use the Evo and also own a NookColor.

Ok i'm confused by this part...
No one was really talking about the 4.3 inch screen..
ANYWAYS the dvd quality vs 2100 stream HD by that do you mean a 2100/kbps steam?
if thats the case then its not a surprise seeing as 2100/kbps is enough to stream at 480p.... which is dvd quality

OP's original question was about "I will be converting 720p .mkv movies to .avi format with 1024x600 resolution and 2,000 kbits rate to get the best video quality."
Later after some responses he comments he gets better resolution on his HD2 (that is a 4.3" screen) so he will skip the nook.
You still point out a misunderstanding I had now that I go back which is that he is starting with a 720p source but ending up 1024x600. But really this is just makes my point stronger because then we are looking at an even smaller difference in the resolution.

Resolution for Ripping DVDs for Nook

What resolution and file type is best for the Nook Color? I tried one at 1028x563ish and it won't play. I have another that is like 420x800 or something like that and it plays but picture quality isn't quite as good as it could be (worse than streaming content viewed on the nook). What have you guys had work well for you? I have been using mp4 files cause they will play on my nook and my wife's iPad

The search function is your friend...there are whole discussions on this subject. To sum up...854X480 is the Max resolution for hardware based playback. There are multiple links to various handbrake presets...the one I use is set to 1k kbits.

MoBo Player is also your friend. Works well with just about anything.

Try 512x300 (a quarter of the Nook screen) at 600 kbps with 96kbps audio. More than sufficient!
I know it's not as good as the max res the Nook supports but it allows you to put many more movies on it at the same time...

I usually use 852x480... I didn't know about the 854x480 limit - I'm not sure where I got 852 from. I use ffmpeg to rip... the most important thing is to have -vpre baseline in the options or the video may not play. Mp4 supports a ton of different options when encoding, and baseline makes sure that nothing is included that the nook can't handle.

I use handbrake and set video to 1024x576. Mobo plays this perfectly.
I realize this is beyond the max rez, but with Mobo it is gorgeous for playback.

Just note that your battery life will suffer considerably compared to encoding the video so that the DSP can handle decoding.

I use Cucosofts dvd ripper ultimate.this software is capable of converting to just about any format out there.I've had great success with mp4 itouch settings. Set to maximum bit rate for the best picture quality possible.Rips and converts any dvd I've thrown at it.Audio and video quality is great.

[Q]Can the D3 stream YouTube 1080p with flash?

Hi guys, can anyone kindly help me test if the droid 3's CPU is capable of streaming yotube videos in 1080p in flash. i am thinking of getting the D4 which shares the same CPU as the D3 except with a higher clock.
i know Samsung's S2's CPU(the exynos, not the tegra 2 version) is capable of handling youtube's 1080p. i would really appreciate your help.
PS: i sympathize with those who purchased the D3.

I'm sure it has the ability to do it, but I've never done it before..

i need someone to do an actual test to confirm. the tegra 2 for instance, despite having 2 cortex a9 cores like the exynos, can't handle 1080p in flash.

Let me check.. but I don't see why you would play a 1080p youtube movie when the screen is only 960x540. 720p would make much more sense (1280x720)
edit: when I go to the desktop page of youtube it says I need to upgrade flash player but I have 11 installed.
Opening in youtube app only lets me choose between HQ and no HQ

perhaps you have not enabled plugin in the setting? maybe you can try another browser? i am aware that 720p is good enough on the phone's screen, but the ability to stream 1080p in flash will proof that the D3's CPU is just as capable as the exynos since the exynos is the only CPU that can handle 1080p in flash afaik. it will also be useful when i output it via HDMI onto my 65" full hd tv since 1080p looks much more clear on a such a big screen. i appreciate your effort anyways.

Its downscaling anything above its 960x540 resolution, but when I tested Flash player it was able to do 720p no problem. When the quality is switched to 1080p the video frame rate drops to nothing but the audio still plays. This is in Dolphin Browser HD with a desktop user agent.

Well flash works fine in mobile version. The desktop version probably looks for desktop flash. Btw just for the record my D3 plays 720p MKVs fine (2GB - 1hour), which probably has a higher bitrate than those youtube 1080p's

yeah i know, my xoom's tegra 2 can handle 8gb 1080p MKVs with no problem, but when it comes to flash 1080p it just stutters like mad. i am not sure why your flash doesn't work in desktop version, maybe you need to change your user agent to desktop. i have no problem with flash on desktop youtube on my phone. mind if i ask what browser did you use? i am currently using dolphin browser MINI with desktop user agent with plugin set to always on.
PS: the android flash is the same as desktop flash, they are just coded for different platforms unlike flash player LITE which is found on Nokia phones. i am very certain that youtube's mobile site does not use flash, it uses the phone's built in player instead to stream the content.

It's not about power but also about optimization.

In this case it is about pure raw processing power the tegra 2 is a more optimized than the exynos at the moment due to its mature drivers, API and all that but it still loses to the exynos despite having the same structure as the exynos.
If you look at synthetic benchmarks, you will notice that the exymos is slower than both the omap4430 and the tegra 2, yet in real life, it is the fastest. I have tegra 2 overclocked to 1.6ghz and it still cannot handle 1080p flash. Even though flash claims to be GPU accelerated, it is extremely taxing on the CPU.
Samsung always seems to produce superior chips than its competitors, just take the Hummingbird CPU in the original galaxy s, it is still the fastest single core mobile CPU on the market.
As for your flash problem, have you tried reinstalling flash from the market? You might have to wipe your dalvik cache.

I just tested on my d3 to see.....it worked! I mean at times it wasn't butter smooth and hesitated occasionally but played just fine overall. 720p looks the same on the screen but is butter smooth constantly so yes....the d3..mine at least...can do 1080p youtube. Running cm7...init.d hack. Didn't even use my overclock haha

[Q] Resolution Question

Hey, I'm about to buy a chromecast, but there are something that stops me. If I have a phone with quad hd resolution, does it stream in that resolution on the tv, or does it stream up to 1080P?
Another question is, is there any known issues with the chromecast? I just want to be sure.

Well you can't tab cast from your phone. It streams directly from the internet and doesn't display mirror. So it will stream whatever the source content and your TV resolutions are.

Quad HD? Like UltraHD (3840x2160)?
Casting local media directly (via Avia, RealPlayer Cloud, or Allcast for rooted Chromecasts) is as-is, no conversion of the media happens, and Chromecast will play the media if it is capable of decoding it.
I don't think Chromecast can decode UltraHD as it tends to have trouble with 1080p and high (>10 Mbps) bitrates, but I'm not 100% on that. I can use AllCast to send a 1080p video I shot on my phone, but there's a little bit of pause now and then.
As far as known issues, some old TVs that report 1080p support but don't actually display correctly have trouble. Some Yamaha receivers are having some trouble with the latest firmware.
Most other issues are either in progress or have already been taken care of via updates on the application side.
A tiny number of reports of Chromecasts being "bricked" but probably normal or better for the number of Chromecasts out in the wild.

There is a phone with QuadHD resolution?!??!??!??!? LOL
There is a lot of Misinformation regarding resolution in the Phone business I assure you...
Cameras that say they shoot 1080P in most cases don't. The Chip (CMOS for the most part) does not have a REAL 1080P resolution. What it does is take the native resolution of the camera (usually much lower) and SAVE THE FILE in 1080P by simply upconverting it.
And Upconverting doesn't ADD resolution or Quality it just doubles the size of each pixel to fill in all the pixels of the higher resolution.
You may find a phone or Camera that says it supports 4K but in truth it is not a REAL 4K! The File will read and display on a 4K device but your not really getting the FULL RESOLUTION a 4K video has when captured natively in a TRUE 4K.
The Chips that receive the image from the lens are not large enough to do a true 4K. It is merely upconverted when saved to that format.
Like taking a single pixel and repeating it 3 more time to make a pixel 4 times the size of the original where in a REAL 4K each pixel can be different and rarely are the same (maybe similar but not the same)
Now these chips are improving by leaps and bounds so in time they may even do these resolutions for real...But by then we will also have things like 16K because the bigger cameras with have 3/4" and 1' CCDs or CMOS' will advance from the technology as well.

I'm sorry regarding quad hd, english is not my first language, and when I meant quad hd, I actually meant 960x540. I know alot about resolution, but I didn't mean 4K. Before 2K and 4K, there was quad hd as 960x540.
I have good internet, so I don't worry about that.
Thank you all for your answers, I'm going to buy a chromecast when I come home.

Ahh, I see qHD from the computer realm. Thanks for teaching me something new! :good:
I have some VGA (640x480) videos and from Avia they play picture-boxed (black border on all sides, because Avia does not alter the video). So it will likely depend on what application you use and what Chromecast decides to do in terms of scaling, if it has any (I don't know).

I think the biggest reason it can't do 1080p natively is because it's wireless G. I can only hope Google decides to release another chromecast or something else like it with wireless AC.

It's wireless N which is more than adequate. It depends more on latency and bitrate of their media compared to that processing power of the Chromecast hardware.

It can't do 5GHz, and its horrible at streaming HD movies from Google Play movies. You mention processing as if the Chromecast is transcoding. None of this would be a problem if it could do 5GHz and had an AC chip.

Edit - My Samsung UN46F6300 is also terrible at streaming HD content over it's Wi-Fi (also 2.4GHz), but connecting the tv's Ethernet to my WD wireless AC bridge alleviates all this.

Yes the 2.4 GHz band is not optimal as it's crowded but latency issues aside, it's fine.
The hardware still matters because most hardwareand appliance-oriented decoders have limits to the maximum bitrate it can decode due to buffer and memory limits.
It's much different to more general CPUs which can allocate more memory and have more CPU power to adjust.

Well I'm pretty sure GPlay does some transcoding but not 100% sure. In any case If the unit is having issues playing the video over 2.4Ghz the issue is really the Video Bitrate needs to be lowered enough to stream without issue. In the end no one is getting full HD 1080P on any device over ANY wired or wireless network because Full HD uncompressed has a Bitrate of over 1.49 Gbps. Far beyond standard Ethernet standards which is why we use Fiber Optic for broadcast and even then we compress the hell out of it before you ever see it.
So pretty much all HD we are playing is not really full HD.
Can you play 1080P locally?

Ahhh no Problem...You meant quarterHD actually...
You wouldn't have confused us if NHK and a Consortium hadn't actually invented QuadHD for Broadcast! bhiga and I both work in broadcast and were recently talking about it.

Well, I forgot that it was Quarter HD, but it's okay now, since I have aleardy ordered it. Again, thanks for your help guys.
