Play 720p mkv?

Hey guys,
I was thinking about buying a Nook color but I had one question.
Will the Nook Color be able to play 720p mkv files? With subtitles? I noticed that the archos 70 can play 720p mkv files and It seems to me the cpu is similar in both units.
I am pretty uninformed about this topic so I was hoping if anyone could enlighten me? I did not want false expectations that one day someone will be able to get it to work on the Nook Color.
Btw I know that Nook Color can not play it natively, but since the archos 70 I was wondering if the Nook Color could 2 in the future?
Thanks for your help!

is there an app?
At the moment, I don't believe the nook will play .mkv files without rooting it. I haven't rooted mine yet (waiting to see if 2.2 really does come out next month and what changes it brings, first) so can't say if there is an app that will play them.
I would think that it could, as long as the necessary app is installed and the codecs are available. The hardware seems like it would be perfectly capable of playing a 720p file, no matter the format, it would just be squished down to the correct resolution of 600 (or smaller depending on ratio).

Don't know about 720p, but as long as the video and audio streams are something the NC recognizes it should play an MKV (h.264, mp4 for video, aac or mp3 for audio). Although I had much better luck with just straight up mp4 files.
The built in player only even showed subtitles if they were hardcoded to the video.

i can play 720p mp4 files just fine with no lag what so ever.. Quality is awesome.. Rock Player doesn't like MKVs or AVIs, it will play them just really really slow..

Are you using the stock player or Rock Player?

rock player plays mkv's fine on my evo but i cant get it to activate on my nook

mvideo player plays mkv 720p anime with subtitles that i have on my samsung captivate. (although it seems you have to start the video from beginning to end (ie: can't skip around) or the audio will get out of sync)
wondering if you download android market and get mvideo player if mkv 720p subtitles will work on nook color as well.
if so i would be interested in the ereader/tablet

Why? The root takes approximitly 15 to 20 minutes. Is practically completly automated, and improves the device 500%.

I loaded up a 800mb standard def AVI and it played fine in rockplayer. Bit of stutter at the start but it smooths right out after about 10 seconds. Just FYI

Nook Color can only play these video formats: 3GP, 3G2, MP4, M4V, and OGG. And supports MPEG-4 Simple Profile up to 854×480, H.263 up to 352×288, and H.264 Baseline profile up to 854×480. So if u want to enjoy video on Nook Color, u should convert video to Nook Color compatible formats. I suggest u a powerful video converter called Foxreal Video Converter, which enables convert all video formats to Nook Color with the optimized video format (MP4, 854×480, H.264 codec, 1500kbps avg bitrate, AAC 48KHz 160Kbps) to give user the best visual enjoyment.
U can try it, hopefully it can help u.

You can download an app from market and then you can watch rmvb on Nook Color. So, your post is not 100% accurate.

There are a couple apps vplayer and rockplayer that can play just about every format on armv7l (our cpu)
More importantly I heard the ffree and awesome VLC player is coming to android VERY soon, that will be the best for the NC for sure

I have tried half a dozen video apps and have been unable to play 720p mkv.

720p youtube vids don't work
I tried downloading 720p and 1080p videos from youtube with tubemate and they wouldn't play. They'd skip and stutter - totally unwatchable.
Also just tried playing a 180meg 720p AVI of the office in VPlayer. The video plays fluidly but the audio is completely out of sync.

I'm afraid 720p and 1080p are out of the question.

What's the point of 720p on a 480p device? Do you just not want to convert your video files?

Vplayer works better than rockplayer. Plays mkv. Ratings are bad because developer said application would always be free than started to charge for it. Paid version is highly rated

Because the nook's screen is 600 pixels so 720 would be the smallest "standard" size that doesn't have to be up-converted.

I play mkv files on my HTC Desire - Rockplayer and others all stuttered and displayed a blocky effect.
Then I installed Vital Player (neon) and they all player wonderfully - even 70p ones! For some reason it struggles with 720p mp4 files but who uses those?

The chip that handles video on the NC wants to play video smaller than 854x480.
Any video larger than that will not go through the hardware accelerator.
I have a thread where I attached a handbrake preset for the NC.
http://forum.xda-developers.com/showthread.php?t=992214
If you use that preset, you have to set the video size yourself (defaults to original size)
Use the original size if it is smaller than 854x480. If it is larger (like 720p would be) then set it to 854 width with "Keep Aspect Ratio" and the video file that handbrake puts out will be nook hardware accelerated.
Also, MoboPlayer is much better than the alternatives as far as the player itself goes.

I read entire thread but I really want to know why archos 70 or 101 (with same GPU!) manages to play 720p hardware accelerated.

HD Video for G Tablet

I wanted to see how an HD movie plays on the G. I tired to play an Apple Quicktime HD Movie trailer and no go. I also tried to play an HD Trailer from Yahoo movies and no go, it said "download failed".
Can the rooted G with TNT 2.4 play HD Quicktime movies? What's the best way for me to test this out?

From what I have read, the g-tablet has some very specific requirements for viewing 1080p files. I know for a fact that it will play MP4 H.264 so I just encode everything to that with Total Video Converter.
I haven't tried to play a .mov yet on it. I have a couple that I downloaded from the web that I should try.
Edit:
Just tried a 1080p .mov that I downloaded from youtube. It plays in Rock Player with software decoding, but really bad.
I suggest downloading hd content to a computer and converting to mp4 h.264 because we know that is supported by the tegra hardware.

I am really disappointed with the quality of video playback on the G Tab. With everyone jiving about the great hardware specs, I don't see great video playback. Unless I don't have it maximized right.
I downloaded a couple of converters and converted movies from mov to mp4, avi, and wmv. I also used Roxio Creator 2009. Nothin greally plays all that great.
What am I missing?

The best converter for the g-tab, in my experience, is Handbrake. I use the built-in Regular-Normal profile and change h.264 to mpeg4 (because tegra 2 has issues with h.264) and it plays completely smoothly at 720p and 1080p.

It plays .mov containers - the Tron Legacy trailers come to mind.
It has some trouble with mkv's and mulitple audio tracks, and HiDef h264 videos that are encoded in "high profile". That's been my experience.

There's no video player (that I know of anyway) at the moment that is designed to take advantage of the tegra2 hardware. Once there is it will fly. The G Tab doesn't seem to support a lot of codecs as well.
I've had success playing 720p x264 MKV's up to 4GB with Rockplayer and ES Video Player.

Excellent. Thanks everyone for the input. I'll check some of these tonight.

Thanks. This converter works great.

Well that didn't take long: http://forum.xda-developers.com/showthread.php?t=881835 - Rockplayer 1.5.x (Tegra 2 optimisations)

Has anyone sucessfully played a 1080p video?
I have tried mpeg4, mkv and h.264 and they play but the sync is off and they are very choppy.
According to Nvidia's website the Tegra 2 is supposed to have an on-chip h.264 decoder and encoder on it. But nothing seem to take advantage of it. Even the new Rockplayer with the Tegra 2 Optimization.
If anyone can let me know how you encoded 1080p to play on your tab I would be greatful.
EDIT:
For anyone else looking, I got 1080p to work on mine with Rockplayer 1.51 and hardware decoding. I donwloaded a youtube/vevo 1080p video and ran it through Handbrake. Normal profile, MP4 container and MPEG encoding. It plays FULL 1080p very smooth that way.

MKV Player

Searching for player which playes mkv videos including its subtitles without converting it into some crap. Tried Rockplayer and mvideoplayer but without luck.
Any suggestions or advice ppl?

am using vitalplayer and it's quite good with my mkv files....though i haven't really tried on a movie with subtitles.

Rockpalyer works great!!
But i'm interested in subtitle too

Rockplayer works for me.

I'm not sure how QQPlayer handles it, but it's another free (great) video player worth downloading and trying.

Only phones with native mkv video format support can play .mkv videos efficiently. So, forget about mkv, it doesn't matter which player you use. But anyway, the best video player for me is RockPlayer.

Try Vital player. It supports SMI and SRT subtitle files.
But i don't try mkv files. It should work coz rmvb works.

..
QQ Player works great on My HD2.

Vitalplayer works fine.

Mediacoder
I think the best method would to just burn the subtitles into the encoded video...
Furthermore, MKV container can support a lot of different video (most commonly h.264)...
either way, it would be beneficial to convert to h.264 video and aac audio in mp4 container... Then virtually all target devices can play the file. You'll run 720p that way a lot better too (480p ideally to save space)
So, if you have a nvidia card with PureVideo2 I definitely recommend this method...(or a decent cpu)
mediacoder has cuda encoder bundled with it to make quick work of video->mp4
Here are some of my settings that I use in Winmo, plays back flawlessly on android too.
Video:
Avg bitrate - 1200 (you can set it higher if you want... you'll just get a bigger file size with marginally better quality imo)
Format - h.264
Encoder - Cuda (NVidia cards) , ffmpeg (cpu encoding)
Audio:
Format - LC-AAC
Encoder - FAAC
Avg Bitrate - 128 MPEG4
Container - MP4 (select it in both audio and container tab)
Picture:
Resize - 800x480
Aspect Ratio - Set pixel AR, 1:1
Crop - Disabled
Subtitle
Renderer - Default
Scale, position, outline, blur) - adjust for subtitle appearance
ID - 0 to # (set according which subtitle you want to use from the source video
These are just some loose settings to get you into ballpark range...
make sure you preview before you encode a bunch of files and make sure it works on the device.
I also think there is a "portable device" edition of mediacoder
Sorry for the long post.

mobo player plays mkv with subs but it isnt the best. good enough for the meantime till i find something better.

MKV app

Anyone know of a good app for Honeycomb that will play various video file types including .mkv? I have tried QQplayer and Vplayer but the its real buggy on the xoom. Thoughts?

There are threads all over the general section on this issue. No application will play a high profile MKV on the Xoom. The native video player can play MKV files but it has to be baseline encoded. You will need to use an application like Handbrake to convert the HD video using the universal preset available on the application.
http://handbrake.fr

I haven't used it yet for Mkv but rockplayer is a great app I use to play avi files.

I've been using the full version of xvid4psp to recode x264 mkvs. Technically you can just copy the video and convert the audio to aac and push into a mp4 container, but my Xoom wasn't able to handle 1280x538 or whatever a 2.4AR movie is. I converted it to 1024x430 and was still laggy when playing with Act 1. It only takes my notebook about 2.5 hours to re-encode a movie that way so I'll probably stick with 848x352 or 848x480. Though I fear that might make it lag at full 16:9 480p so I might have to look at different profiles to make it less complex of an encode.

[Q] Divx playback (neverending story...)

Hi!
I have been struggling with this topic for a few days now. Read most of the threads written here on this too. I know about the limitation of hardware accelleration, and understand it. I have created presets for Mediacoder (+CUDA) perfectly working so that I can quickly convert what I want to a video format being very well played by on nook with hw accelleration.
I am aware of the fact that videos encoded with xvid/divx can only be played with software decoders. It's been reported here such videos are pretty well handled by players like Rock-,Mobo-,YXplayer and so on; I assume nook's CPU has enough power not to have issues with ~620x350 XVid encoded video. Well, mine seems to have one.
I tried out a couple of different .avi's I have. Just one specific example:
an episode of some TV show:
Video: 310 MB, 1037 Kbps, 25.0 fps, 624*352 (16:9), XVID = XVID Mpeg-4
Audio: 38 MB, 130 Kbps, 48000 Hz, 2 channels, 0x55 = MPEG Layer-3
This one is being played fine even on my old PPC Axim 30 (Intel XScale PXA270 at 624MHzwith TCPMP), but with no means on the nook. Test results:
- RockPlayer -> slide show
- YXPlayer -> slide show
- YXPlayer Neon -> slide show
- MoboPlayer - almost the one. The only one which plays completely flawless video, but the sound is out of sync, about 1 sec behind the video
What am I missing/doing wrong? Such a file should be a walk in the park for a Cortex A8 at 800MHz, shoudlnt' it? Is it about me using a rooted stock nook? Would froyo did the trick?
Regards,
Maciej

So you're on stock? Have you overclocked your setup? If so do you have governor set to Interactive and the Min. Cpu set to atleast 800mhz?

Found your problem. I find that the nook can only do 24fps or 29.999999fps. You must be trying to play a European program. Re-encode in Handbrake and change the "Framerate" drop down box to the NTSC Video setting.
While you are at it, in Handbrake and all, you might as well re-encode using x264 to take advantage of the Nook's hardware decoding...

Generally? Or in terms of software divx/xvid playback? I re-encoded the file to H.264 WITHOUT changing the framerate and it works smoothly. For the hardware accel the framerate is not an issue.
I wonder what the problem could be: the sound isn't stuttering, the video is smooth, they are simply not synchronized. It cant be due to lack of power,can it?

The NC supports hardware decoding of MPEG4 (i.e. Divx/Xvid) Simple Profile but it has to be in a MP4 rather than AVI container. Unfortunately MP3 audio is incompatible with MP4 containers so the typical AVI needs to have at least the audio re-encoded for hardware playback on the NC.
It's not unusual to have poorly muxed AVI files where the audio and video end up out of sync when re-encoded. I'm not sure about Mediacoder but Handbrake does not easily allow adjusting the audio offset to compensate for that. You might try aviDemux (open source) as it does allow adjustment of audio offset. Unfortunately, it's trial and error to figure out the proper offset. If your Divx file is MPEG4 SP then you could just set up aviDemux to copy the video, re-encode the audio to AAC and mux in an MP4 container with the appropriate audio offset.

For me just software divx playback. My 25 fps files just never play well.
For x264 you can do any framerate up to 39 fps I think, as long as the bitrate is low enough. For me in Handbrake the magic number is a Constant quality of 22

@razmajazz
Sorry for the confusion. I have no issues with any x264 re-encoded file, as mentioned in my first post - my Mediacoder preset does its job perfectly.
I mean MoboPlayer plays the original Xvid video and audio very smoothly, they are simply out of sync, which doesn't look like a CPU power issue to me. As poofyhairguy said, it must be about the framerate and some incompability.
Re-encoding doesn't bother me, I only wanted to avoid it if possible for lower quality divx/xvid films. And the MoboPlayer seemed to be only an inch far away from the right solution.
I will do some testing in the afternoon.
Thanks,
Maciej

Are You playing videos on stock, rooted Nooks?
Or Froyo/CM7?

DSP drivers/Hardware video decoding is critical for smooth playback.
I dont know why the CPU cannot do it fast enough. (software decoding)
Thats why I'm on nookie froyo
No sync issues or anything with normal res videos from the interweb, no recoding needed, any decent MPEG4 player plays smooth.

Indeed I was confused. I thought both the original and re-encoded files had audio sync issues. As long as the video stream is MPEG4 SP, you may still just want to copy the video, re-encode the audio to AAC and mux in a MP4 container. It's pretty fast since you only have to convert the audio, you don't lose quality from re-encoding video and it plays back with hardware decoding on the NC.

Success!
Yesterday I ran nookie froyo from SD. MoboPlayer plays all files perfectly, no out of sync! It was that simple...
Thank you all for your suggestions!
Cheers,
Maciej
