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.

Yes, I went back and looked up your thread since I successfully used your presets and wanted to say thanks. They worked great and the results made a long flight from Denver to Orlando very enjoyable !

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.

There's no hardware video decoding on Froyo yet.

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.

[Q] HDMI 1080p for Photos

I currently have CM7 installed, and the HDMI mirroring works great. But when I view photos, the resolution is not 1080p, it's the resolution of the screen. Is this possible to view photos at 1080p resolution over HDMI on CM7 or stock ROM?

This is the main problem of this STUPID hdmi out. It's only mirroring. that means the resolution of the screen is the ONLY resolution in OUTPUT.
then the 800x480 resolution is upscaled.
Viewwing photos or video we had the same problem: also video in full hd that this phone can play smoothly, BUT the hdmi out is ONLY 800x480...so...it's useless that this phone can decode full-hd video....

When watching video over HDMI is look better than 800x480?

When I record an HD video on my phone, the play it via HDMI out, it seems to be full HD. I was hoping there was a way to do that for photos... I guess not. Perhaps it can be a feature in CM7 or something.

just last sunday i was watching 1080P on friends TV. no problems!

Or you think you did.
Everything is downscaled to phones screen resolution (480x800) and then on HDMI out stretched to 1080p just so that our TV's don't have problems with it. That's why it is not pure 1080p, and that's why it doesn't really make sense to force HD videos on phones.
Use PC, media players or anything else HD capable instead.

No. True for photos displayed on the phone, yes, but not for video. When playing video (at least with the stock player) it no longer does mirroring, it outputs a true hd-image.

Well that's an improvement then. Good news, for some people.
HDMI was for me one of biggest advantages O2x had few months ago, and now I find it almost useless. Yes, it's there and it totally works, I bought the cable and HDMI coupler so I can extend it with another one - but never really use it. Photos were always too blurry to care (when displayed on TV, camera is decent), videos are not so practical even though they work better than I expected, some using stock player and some using MX Video Player.
I have PC connected to TV, Picasa, media server, and PS3 which work far better. Oh well. Still, phone makes a damned good remote controller

It's not an improvement. It's been that way since the phone was released.
Still its a pain in the ass that it won't work with photos.

your information is wrong, it outputs in full hd.
If it were outputting at just 800by400 on your hd tv you would bloody notice because it would be pixelated and difficult to make anything out if it had been stretched that far to fit a large tv..... .

OMG seriously, really?
My post was already debunked by TrymHansen. Try to write something useful, ok? Quoting it again is just counterproductive
Anyway, part about HD video is debunked, I was wrong and life goes on. But I still stand behind blurry low-res photo gallery and that is the topic here.

I'm totally with you at this. I can not help the fact that most of the people are blind and can not recognise the quality and resolution of a picture or video.
The hdmi output for the photos are totally unusable, it displays the photos in low resolution and low color depth.

[DEV] Possibility of h264 720p high profile playback on Tegra2 -EDIT

Currently, tegra2 devices have problem on h264 playback.
But, Optimus 2x updated their firmware and enabled it.
I am using Atrix and wanted to play h264 on my phone.
Of course DICE player can hardware accelerate it but not by streaming flash.
And other players still have problem.
I did a test on several movies and found a interesting thing.
High profile movies are not really different from baseline profile movies.
Here's some example.
http://dl.dropbox.com/u/52685869/CES-News First Look on Samsung Galaxy Tab 11.6.mp4
http://db.tt/ULTADHdo
These two files are exactly same movie file exept profile info on file's header.
(I didn't reencoded it!)
I've downloaded this from youtube and just changed the movie file.
So upper one is just a copy of youtube 720p h264 high profile,
and bottom one is same file except I modified profile info to baseline.
If you play upper one from tegra device, it says file cannot be hardware accelerated or not supported.
But, bottom one can be hardware acceerated and played on android stock player.
So the idea is, if we can change the profile detection method of android,
tegra2 will try to support hardware accelrate on more files.
Maybe even youtube 720p can be streamed on tegra2!
I've searched through android source and found this.

This is from https://github.com/Atrix-Dev-Team/a...gingerbread/media/libstagefright/OMXCodec.cpp
Since I am completely out of programming things,
I can't modify these codes. But somebody should be able to do this.
Help me please!
EDIT- Adding method what I tried on changing profile.
I used HEX editor, HxD to modify movie file's profile.
You can get it form here : http://mh-nexus.de/en/downloads.php?product=HxD
1. Open the h264 file on HxD
2. Press Ctrl + F and search for 'avcc'
3. You will see like this.
4. You can find '64 00 1F' near from digits of 'avcc'.
※ 42 E0 – for Baseline Profile
4D 40 – for Main Profile
58 A0 – for Extended Profile
64 00 - for High Profile
1F (31 in dec) is level 3.1
29 (41 in dec) is level 4.1
33 (51 in dec) is level 5.1
So the '64 00 1F' means 'High profile 3.1'
5. Change the '64 00' to '42 E0'
6. Save the file. (HxD automaticaly creates backup file. So you have to disable it in setting if you don't want.)
So you can test this method for your own movie file.
But I hope someone make some edit on android source for this so everyone can enjoy it.

You are awesome!

Interesting.. Dice is the only player that plays it in hw mode. Doesn't play at all in android player for me.
Still hw accelerated playback for mp4 if cool.

I realise that you must be spending a lot of time 'finding' things when you make these mods.
Do you use 'Examdiff Pro?' It's an awesome tool that compares two files and highlights all the edited files. Clicking on the edited files will open the .txt/.xml/etc and all changes will be highlighted either side.
There's a 30 day trial, but it's absolutely awesome IMO.
It's worth at least a look.

@Notorious: there're a log of diff tools out there, see http://en.wikipedia.org/wiki/Comparison_of_file_comparison_tools
Is ExamDiff Pro the best you can find to compare binary files?

I can playback 720p and 1080p .mp4s on my Motorola Atrix 4G without the slightest problem at all. If you interested in exactly how to do this I can show you how. The only problem is on cm7 roms u can't send 1080p to a tv via hdmi yet. If your running a blur rom with the 1080p hdmi landscape mod you could watch intensely unbelievably high quality 1080p bluray quality .mp4 files from your phone. It can handle like 20Mbps or more I think. The only limitation is the FAT32 Filesystem limit. So your movies will be limited to 4GB however they look f*ing insane anyway and your playing them back on your phone! I love blowing away my friends with my phone. The motorola atrix is an F*ing POWERHOUSE!
Later
*BY THE WAY* If your interested I can upload a short clip of 1080p that can be played back beautifully in HW using MX Video Player. Please let me know how blur rom's work via hdmi to TV with the 1080p landscape mod! That would blow my damn mind if I could use my phone as a BluRay player. It sucks CM7 is limited to portrait 960x540 over hdmi. Also the FAT32 limit isn't so bad because if u have a 32GB Class 10 SD Card like me, you can put a couple stunning full length 1080p blurays at 4GB a piece. The main limit is in the bitrate because of the 4GB limit. If a 64GB class 10 comes out I'd jump on it. Also when are we going to upgrade to "Today's standards" as NTFS format on Android. Is it a linux limitation for FAT32 or something?

It is not a OS level modification.

It would be so great to do like that without reencode.

Sure. Yes. No need to do any development. The atrix is fully capaple of decoding some jaw dropping stunning and unbelievable 1080p BluRay quality movies without any problem at all. It can also carry over DTS 5.1 to your receiver if you want. Ok so the key to decoding 1080p on the attrix lies within Xilisoft Video Converter Ultimate (I'm using Version 6.0). I can tell you exactly what profile and settings to use. What I want to do is upload a clip of 1080p footage so u guy's can have your minds blown by it. It can be decoded with MX Video Player without a problem @ 1920x1080 @ 20Megabits or more. However the FAT32 filesystem 4GB limit limits a typical full length BluRay to 3Mbps. Which honestly look f*ing insane still! I'm trying to find a way to upload a file on here. What's the file size limit? Like 10MB max or something?

You can upload it to dropbox and link it to here.
Or use multiupload.
Edit- Wait, so what you want to say is.....reencoding?

Video Playback on the Nexus 4

Hey guys I plan on getting a Nexus 4 soon and I would like to know how it handles videos beforehand.
If possible could you guys treat the following:
High bitrate 1080p mkv playback (BD encodes if possible)
720p 10bit mkvs
1080p 10bit mkvs
You could try to play 1440p ones but I don't really mind.
What formats does the player in 4.2 support?
Does it support subtitles?
Had any problems with specific audio codecs?
I'm concerned about this because sadly the Nexus 10 can't handle 1080p 10bit mkvs, that was to be expected though, however I think that the superior CPU in the Nexus 4 might be able to do just that and the Exynos 5250 with it's Mali T604 was able to play 1440p (or 2600k as some of you may call it) and I was wondering if the Adreno 320 could do that.
Thanks.

What do you mean " can't handle it"? The nex 10 has one of the most powerful CPUs in any tablet. That dual core is amazing.

According to the guys in the thread in the Nexus 10 general it doesn't play smoothly, it drops frames as it's SW decoded, it was to be expected, while the Nexus 10 has a better CPU than any other tablet the difference is not by much (as each A15 is a little more powerful than 2 A9s at the same frequency) and quad A9s can't handle 1080p 10bit mkvs, the Nexus 10 does a bit better though doesn't play them with a watchable frame rate.

Why use a format that needs PC to run? Can't you convert those to a more usable format?

Just tried a Bluray rip of Cars and it played perfectly in MX player minus the sound of course since it was lossless audio. I don't have any 10bit videos at all but if you can point me to a short clip of one I'll be gald to check it out.

I used them because 10bit looks better and it's a pain to convert them
Here man, that's weird I thought MX handled most lossless audio formats, could you try BSPlayer too?
1080p 10bit ones: http://android.tnonline.net/Software/Video/Hi10P Software/
Some other test files: http://www.cccp-project.net/beta/test_files/
Thanks bro.

Puss in Boots trailer you linked to plays fine in Dice Player.
The 10bit hotd blah file does not however.
Also tried BSPlayer but that crashes on opening.

I thought that nex 10 would be amazing for video. The resolution is incredible and the CPU as well.
If I did not already have this nexus 7 and a nex 4 coming I would grab the 10 in a heartbeat.

Don't mistake me, it IS amazing but 10bit, while superior, isn't used much so GPU makers don't make it so their can decode them leaving that task to the CPU which isn't designed to do it.
What happened with the hotd video? Was it choppy? Did it play at all? Thanks

Dice Player said "unable to play this video", VLC beta on same file started to play audio then crashed.

10-bit videos cannot be played without using software decoding. The OP is asking if the CPU on the Nexus 4 is powerful enough for that. The vast majority of mobile devices fail at this task. Only a few phones can even come close to playing a 720p 10-bit file, and even then they aren't perfectly smooth. I, too, am wondering this OP. When I get my phone tomorrow, this is one of the first things I will be testing out.

What about MX or BSPlayer? They play 10bit videos in my TouchPad and SGS2 but as they lack the raw power they are choppy. (they have also proven to be the best players on Android, at least for me)

Yes, I will post about it here tomorrow! I will try one 720p 10-bit file (this one should do fine) and one 1080p 10-bit file (highly doubt this will run smoothly).

Problem with the Nexus 10 is the resolution is more than the GPU can handle.

Anyone tried XBMC on the Nexus 4 or Nexus 10? I literally know nothing about XBMC for Android right now, but I have never had a bad experience with XBMC on any platform.

That isn't related to the video playback problem in with 10bit videos, the Nexus 10 plays videos that take full advantage of it's resolution without hiccups when the GPU is handling the load, 10 bit videos are not HW decoded and thus all the load is thrown at the CPU (which isn't made to decode videos)

2560p?
You mean 2560*1920 resolution?
Or
you mean 2160p which is 3840*2160 resolution

[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.
Sent from my LG-LS980 using Tapatalk 2

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?

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.
