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.

Android video playback?

So far I'm fine with Android but I still complain I playback video in Android doesn't work well. The problem is that in WinMO could perfectly reproduce videos in format AVI, resolution: 320 * 240 and FPS 18 but in Android can't do reproduce only recognized of all videos and movies that I have one that is in WMV, therefore transform a video that I had to that format while maintaining the same settings as in AVI and does not play well is unstable and closes only while playing and I tried moving some things in the converter of video formats and still did not play well.
My question is: is there any hack or something like that to make the playback of videos go better in Android or one player as CorePlayer it was that used in WinMO and had no problems with that AVI video format.
Greetings and I hope help me.

Convert them to MP4. You also might try yxplayer, which plays a lot of avi videos(not all though) for me although it's not free.

Thanks a lot! Transforming it to. mp4 and playing with yxplayer works well but I will have to transform everything again but the important thing is that it works.
Best regards.

I have had most success with arcmedia in the android market. It uses the FFMPEG codec library rather then the codecs built into android which means it plays more file types successfully then most others i have tried. It even has a stab at playing higher quality videos where you would normally only get sound in the standard player, but they still stutter a little.

Thanks for the recommendation but if you saw the answers the problem was solved transforming the videos to .mp4 and using the player YXPLayer, the player you mention does not work but I accept suggestions of other players who have best interface to YXPlayer.

are you saying rockplayer fails to play your original avis? (at least this is what i was recommending it for)

Video playbacks on nook color?

Hi guys, I have searched about the video playback capability of nook color.
I found information that has been posted since december but i am not sure if there are any changes since then. Can nook color play avi and m4v now? without the conversion?
And is adobe flash available for it right now as its already on 2.2?
I seems like I can't get information about it and all i got was about the flashing of nook color. and videos of nook color.
please enlighten me. i am currently so tempted to buy nook color.

Currently video playback is very limited, and hardly any formats are supported. As for flash, it is supported somewhat on the Froyo 2.2 builds for the Nook Color, however, it is still recommended that you run those from the sdcard as the EMMC builds are still highly unstable. With the current progression on Stock, Froyo, and even Honeycomb, we can only guess that flash and video support is right around the corner, especially once A3.0 becomes AOSP.

I use radtools or mcebuddy for batch conversion to vanilla mp4. Works great
NC via XDA

rockplayer in the market will play avi's and what not

thanks for the replies guys!
was thinking of buying it already but it seems like there are no stock on bestbuy.com .
stock seems to be available at B&N but bestbuy gives a free cover.
but bestbuy gotta wait for around 2 weeks! !

I use handbrake (free) to transcode movies to mp4 which plays beautifully on the nook
Alsos use mVideoPlayer which also supports import of subtitle files

i tried to get a nook color through a online store.
But: its out of stock everywhere: b&n, bestbuy, wallmart, booksamillion. even if they say that its in stock, it wont be until the 15.2.
you can try at ebay.com or amazon.com...,

Yeah, be careful with the online inventory counts from Bestbuy and Walmart. Sometimes they say they have units on hand and they don't. I've even heard about people calling into Barnes & Noble and the "kids" that work there said they had several and it turns out they were sold out for days.

guys, try this : VitalPlayer. It's free and it's the best one I've ever had in the market.
It can play avi, mkv,wmv,mp4 as such, the best thing is: its software decoding is SOOOOOOO good. If you just play some videos not in HD resolution, this tool can give you almost no lag, no sound delay experience.
Try it and you'll like it just like me.

I have tried Rockplayer, VPlayer, XYZ, and VirtualPlayer. With all of them my AVI files have the audio out of sync. I tried to convert the AVI's to MP4 with DVDFab and the audio was still out of sync. What program will definitely convert from AVI to MP4 while keeping the audio and video in sync?

Handbrake, without a doubt the easiest and best quality IMO.
I too have tried other video players and have seen audio sync issues with them. Using the built in gallery app on my stock rooted nook though video playback is perfect. I have bluray rips of a few select faves for my son on my nook, specifically coded at 854 pixels wide with constant quality set to 20 and they look fantastic on the nook's standard video player but skip and drop frames on vplayer or rock player regardless of what kernel I run (stock 800mhz or overclocked). I haven't tried playback using vplayer or rock in Nookie Froyo yet, maybe I'll try that tonight.

Same here - I have had no luck with any of the other media players.

Did you try your AVI in your PC? A lot of times, the video file itself may be out-of-sync. In that case, no matter how you convert it, it won't work.

The AVI files play fine on my Archos 70 using RockPlayer.

Played around a little more last night and confirmed that for me playback of my mp4 h.264 videos encoded to meet nook specs play flawlessly in the standard player in eclair and the nookie froyo 0.68 image. Playback in vplayer or rockplayer suffers audio sync issues due to dropped frames though I noted that playback of video in vplayer in froyo was much better than in eclair.
I'm really wondering how it is people are getting flawless playback in vplayer. I expected to see it in froyo seeing as I was using a clean SD card boot image (latest distro) .
Its not a huge deal for me since the stock video player plays well but it does mean having to re-encode my fave TV shows from xvid avi to h.264 mp4 before loading them onto the nook.

The Nook Gallery seems to be the only thing that will playback videos without a video/audio sync problem. I use VideoReo to re-encode my videos into a h.264 format for Android phones. They look great on the Nook. VideoRedo is pretty expensive (I use it for converting .tivo videos) but it is a Cadillac. Handbrake is supposed to be a good free alternative.
Is there any way to get the stock Google Gallery app from Eclair onto a V1.1 rooted Nook?

I'm running brianf21's 0.6.7 Nookie 2.2 image off of the SD card. Flash wasn't working in browser so I uninstalled Flash 10.1 in the market, rebooted, and re-installed.
Embedded youtube videos now working in the browser.
From his thread (http://forum.xda-developers.com/showthread.php?t=922324) the only thing I could see was reported success with 0.5.9 so hope this is helpful.

Handbreak.

What is the current status of video capabilities with rooted CN, esp 720p?

With all the new roms forcolor nook out what is the status of its ability of playing videos, especially 720 mp4 and mkvs downloaded from the internet without having to reencode the files?
Which rom/player combination is best for this?

I'd like to know also. Currently using Rockplayer on HC from the EMMC, and videos from my camera shot at 640x 480 and esp 848x480 are quite slow and jerky. Definitely not something to show someone else.
Anyone have recommendations?

DSP/HW accel is not working in all non-stock roms and is being worked on, but even in the stock rooted, I doubt it plays 720p well enough, unless it's been encoded into an mp4 or something that's natively supported.

That is not true. Hardware decoding works in Froyo, just not in CM7 or HC.
It is true that files need be rencoding in compliant MP4 files for them to work. You need a dual core tablet for downloaded mkv support.

My bad - I only tried nookie froyo on the SD and used it for less than 10 minutes.

I can't get hardware to work in Froyo on either Vital player or Rock Player. Anyone getting hardware decoding to work on Froyo?
How are you doing it?

no hardware accceleration on nookie froyo either for me. Able to play 720p AVI smoothly by using vital player neon on software decoding.

If working hardware decoding means that mp4 can be played with standart Movies application, than yes, it works for me in Nookie Froyo on eMMC.

Sounds like Nookie Froyo is the one to get (for now) if you want h/w acceleration for video.

I've been trying to get high quality video to run on my 2.1 NC for a few days and can't seem to get the audio to match up with the video. mp4 video, 800x480, 1200 bitrate, 25 gps looks great but the sound is off. Pissed.

That bitrate is slightly too high.

I tried all the video players I could grab from the market with my rooted NC.
Rockplayer actually doesn't seem to be very good. It lagged at times. I'm not sure it's using full hardware acceleration, or maybe it's not able to fully use or is not recognizing the NC's hardware acceleration.
The best player for getting finicky files to work was vPlayer. It has a "high quality" mode which I'm guessing supplements the hardware acceleration with software decoding to make up for features which the hardware doesn't support. It was able to play video files that the stock video player and others refused to play. I think it was playing them slower than full speed though - was hard to tell with the video samples I used.
It is a pay app with a free trial. When not in "high quality" mode, it would still play the finicky video files, but with visible errors in the decoding. A couple of the other players also did this. I guess instead of refusing to play, they just throw the file at the hardware and display whatever comes out. But vPlayer was the only one with an option to "fix" the errors. If you're not encoding your own videos, definitely give this one a shot.
I'm using mVideoPlayer for now. It's limited to the same file formats the stock player can play, but I really like the interface (swipe to seek forward/back, long-press in corners to adjust volume/brightness). And it automatically generates lists of videos from a customizable directory list. No more having to search through a file browser - my videos on both the emmc and microsd now show up in one big list.
The main problem is you need a back button to use it. If you don't hit back to stop playing a file, the next time you try to play any video file, it resumes playing the old file where you left off. But if you use softkeys to give you a back button, it puts an ugly circle on top of your video...

Not really true. My Samsung galaxy plays 720p mkv's without issues. That's a single core phone.
I think in reaility we just have to wait for hardware decoding to be ported over.

really hope dev can get h/w acceleration going for custom rom, especially cm7. On related issue, my NC with cm7 can play flash video and frame rate is low though (looks like slide show with 360P video).

Not NC related (haven't rooted yet), but having just played with (thanks to this thread) vPlayer, I can say it is definitely the superior program. My EVO handled a 720p .mkv file that rockplayer gave 6-10fps on, it was watchable and had no sync issues besides the occasional slow-down.
+1 for the tip.

I believe hardware decode works on Android 2.1 Auto Nooter 3.0. I have that installed and it works in rock player and vital player.
One thing to note is the hardware decoder can only decode a max width of 854. So your 720p files will not work with hardware encoding. You will have to re-encode the files.
I used this guide http://www.androidtablets.net/forum...using-handbrake-convert-video-nook-color.html and it seemed to work fine.

best video viewing app?

anyone have any suggestions for the best video viewing app for the gtab?
thanks!

Rockplayer.

Video Player
I'd have to go with MoboPlayer. Much better UI than Rockplayer, and doesn't seem near as choppy. Plus you can have a library type setup too. Check it out, it's free on the market. Also, when I downloaded the one from the market, it had me download an older version when I loaded it up for the first time. The older version actually worked better for me.

I like mVideo player. It runs very smooth on the G tab and it does have a library system with the ability for you to download cover art.

vital
my preference goes to vital player..

It depends on the file and how it's encoded. I've got a bunch of recorded TV that I've compressed to 720P mp4 files for my HTPC. They run about 1 Gig/hour. The only combination I've found that plays them on the GTab is the Calkulin+Clemsyn combo with Mobo Player. Even then I sometimes have audio sync issues. I'm sure I could transcode them on a different setting and get better playback, but that's where I am right now.

So is there a ROM that runs 720 and 1080 videos with hw acceleration ?

Guys, use the hardware encoder and make sure your video file is MP4 H.264 - I said this because I spent 1 weeks just for trying to get better player and turns out ---> It's all about hardware encoding/acceleration.
I'm currently using QQPlayer & VitalPlayer (both free version) and all my videos are 720x480 MP4 H.264 (this give me a good size of file 1.2GB each movie)..AND MAKE SURE YOUR PLAYER USING HARDWARE ENCODING rather using software encoding!
Video converter software that I've been using (IMO) - very low CPU usage, 12hr for 10 DVD movie conversion in MP4 H.264 720x480 with subtitles is WonderShare Video Converter Ultimate - pretty good converter and average CPU usage (all 4 core 3.3ghz) is 15% - repeat 15% all cores' CPU usage....
Tried another such Cyberlink Media Espresso, Movavi converter - LOL they are all running 100% CPU utilization
Good luck guys!

ughhh dude....You WANT IT TO BE 100% CPU utilization................
Unless its using Cuda or Open CL...
lol....

I found a new player I am trying out. arcMediaPro can be found on the Market. It has some great configurations but it too struggles with some HD movies. I use my GTab as a video player to hand my drivers to review their practice session as they get out of the race car. Just grab the microSD from the camera and put it in the GTab and launch the video and hand them the GTab. I do notice the audio has some syncing issues on some recordings but I am still going through the settings which are more complex than any of the other video players I have found. Here are a couple of links to these in-car videos..
