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.

Nook color's GPU limitation. Max it can play back is 854×480.

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.

[Q] Best Video Player is?

Been trying to find a good video player...all seem to lag quite a bit or are quite choppy...anyone have any luck with any working really good? If so, please share!

I like rockplayer. Used it for a bit on the plane yesterday.

Is there a certain resolution you encoding videos too or will rock player handle anything?

i have an android phone and I use both rockplayer and mvideoplayer. rockplayer handles avi files well but not mkv files. mvideoplayer handles both.
i don't have a nook color but I would assume if you have a rooted nook(and have access to market) you could get these players and they should work since the processing seems the same.
i'm interested in a rooted nook color but can't seem to find if anyone has actually tried these apps.

rockplayer on the nook can handle 480p non hd videos fine in the mkv or avi containers. anything higher than that and you start to get audio and video seperation because the proc cant keep the video going at the propper pace

im using mplayer on mine right now and watching some mp4 videos, not an hd file ... but the proper ratio and it looks killer ... totally worth 250 bucks

vplayer
I use Vplayer beta and i strongly recomend it. it plays most videos well and only lags a bit when you get to real high quality videos

i bought a nook color and tried it out...so far video playback is not that great.
mvideo player seems to have a very slight audio lag when i played a standard avi file(not converted or optimized for nook color) and no mkv files work on any of the players.
i think this has something to do with the internal videoplayer itself and not really the actually processing power of the nookcolor.
looks like i will have to just convert files to mp4...an extra step but I read more than watch videos.

If you are using anything other than an mp4 file extension then you're using software decoding. Software decoding will only go as smoothly as the CPU allows. I've found when using software decoding I can handle AVIs up to standard def in Rockplayer. (480) I get a tiny bit of stutter at the start, but it smooths out within 60 seconds.
However, if you use hardware decoding, (only works with mp4 files) you can probably push the resolution up a bit. I have a 720x400 file at a video bitrate of 800 that plays instantly and smoothly in the native player and in Rockplayer. I plan to go home and push the resolution a bit further and see where it starts to desync, so once I do I'll report back.
tl;dr: Anything other than mp4 has to be standard def or lower and played in a 3rd party player that can do software decoding, like Rockplayer. Anything in mp4 can be played in anything that does hardware decoding, and can probably go quite a bit higher than SD.

I encountered an error while installing vplayer beta. didn't you get any?

Playing MP4 videos on rooted NC?

I transferred several MP4 videos I shot with my G2 onto the rooted NC but they can't be played.
I'm guessing that because the NC doesn't have a camera, it's GPU may not have the hardware codec necessary to play the MP4 files.
Has anyone else had any success playing various video formats?

I had some success using rock player. I was able to load a 1024x576 mp4 video on the nc and play it in rock player. It wasn't silky smooth, but perfectly acceptable for watching. I used handbrake to rip it. I can post more details and maybe upload a sample if you'd like.

Yes, please.
Looking at bn.com it looks as though playing mp4 videos should be working out of the box...
I would appreciate a sample video and your HB settings so I can transcode some content of my own to carry around.
Thanks!

I wans't able to get the video to play with the B&N player as advertised, but that may have been because of my handbrake settings, which as promised are as follows:
Container: MP4 File
Picture: Anamorphic Loose, Width 1024 (to fit the nook)
Video Filters: All Off (shouldn't matter for playback, only for how good of quality the transfer is)
Video Codec: MPEG-4 (FFMpeg)
Framerate: 29.97
Average Bitrate: 997kbps
Audio: AAC (faac), Bitrate: 160
I have a 3MB sample here.

NC default player doesn't support video width above I think 854. You can find the exact specs in the FAQ on BN support.
Audio needs to be aac rather than mp3. To make a long story short, mp4 and m4v aren't video formats. They're containers for a video stream plus an audio stream, and there are a wide variety of video and audio stream types that can go in this container. NC default player doesn't support all of them, but the ones it does handle I've found it handles better than RockPlayer.

[SOLVED] How to play HD video (720p) on N1?

Is there a way to play HD video (720p) on the Nexus One? I have tried some apps off the Market to play these videos but it comes up laggy. The file I was trying to play was an .mp4 file. The default Video app can't play mp4 files and the Market apps lag when playing it. Anyone successfully have HD video playing without lag??? Also, is there a recommended format/codec for the Nexus One?

It's not the resolution of the video per se, but rather the bit-rate that would be causing playback to lag. Bear in mind that 720 is unnecessary anyway as the phone is effectively 480 in landscape.
Use the free software Handbrake to re-encode to a more appropriate bit-rate and resolution.

Thanks. I will use FormatFactory to lower the nitrate.
I'm also a fan of Half Life 2 too.

Yes, It is possible to play 720p videos on nexus on. Actually its chipset supports. you can use mxplayer, it's my favorite player; also, you should convert your video to .mp4 and use H/W decoder. H/W decoder is not supported for other formats like flv.

Large video files won't play

I'm running CM7 stable with the 4/13 kernel and ALSA update, although I don't think any of that is causing my issue. Just figured I'd put out what I'm running ahead of time.
Anyways, my problem: large video files won't play.
I can get "smaller" files to play perfectly, such as the episode of The Office that I've been using for testing. I encoded it in HandBrake to MP4 using 854x480, 1500 kbps, 44.1 and DRC of 3 and it plays beautifully in every video player (stock, Mobo & Rock Lite) with a total size of 260MB.
I encoded four other movies (originally MKV) using the exact same settings with a final size of ~1GB and none of them will play. It simply says "this video cannot be played".
Is there something I don't know about the Nook and larger videos? Do they have to be split? Its not like they're over 4GB, so the FAT32 transfer limit shouldn't be in play here.
Thanks!
