I just picked up my gtablet yesterday and have been spending my time installing tnt lite and installing several apps. I bought it because when I go on trips I wanted something that could browse the net, and play videos. I installed RockPlayer and put a 720p mkv file onto the machine, however playback is very choppy and its almost like the device cannot handle it. I know that several people have gotten 1080p to work good, and I am wondering if there is a setting that needs to be enabled to make 720p work better? I did some digging and saw that someone said to edit a line in the build.prop file (set the media.stagefright.enable from true to false), but I cannot edit my build.prop file. And I am not entirely sure that this will fix the problem. Are 720p videos playable on this machine?
What profile did you render the movies in? Try changing the MKV extension to AVI... Sometimes some renderers treat containers differently even though they are using the same codecs.
just tried to rename the extension from .mkv to .avi and still same choppiness and eventually the videos stops playing all together. I am not sure what rendering is, but the file is encoded AAC 2.0 H264
h264 is not the issue, it's what profile its encoded in
I have this in my FAQ section (in my sig). h264 is supported, but the Tegra 2 cannot handle h264 encoded in high profile. It can handle main profile.
This is confusing to people. So, what I would recommend is to download the excellent "mediainfo" tool (http://mediainfo.sourceforge.net/en) and it will show you how your videos are encoded.
As for container support, I think MP4 plays a little better than MKV, but Rockplayer (in the Market) seems to be able to handle MKV and using hardware acceleration. Again, as long as it's h264 main profile.
This is not just an issue with the GTab - all the Tegra 2 devices will have this issue as its a limitation of the chipset, or so I've read. Vega, Folio, even the mysterious Adam will probably have this same limitation.
Reference on h264 and main / high profile: http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC
Thank you for clarifying. I am wondering can I convert the video to the main profile and then get it to work?

Yeah, that's the tricky part. I haven't been able to figure that out yet, although granted I haven't put much time into it. I think these "profiles" depend on how you encode and which tool you use.
If you try the Tron Legacy trailers, they are 1080p but main profile. A good example of how nice videos can look on it, when encoded the right way.
I have to play around more with something like ffmpeg to see if I can pin this down. Another reason for transcoding is to keep the sizes down, since we have the 4GB FAT32 file size limitation to deal with. Yuk.
I've incoded a 1080p high profile to main. sound was in and out then tryed a few things and lost sound. Video played great anyways.
I guess it depends on the encode. I dl a 720p music video off of youtube, mp4 avc [email protected] (according to mediainfo) and it plays just fine.

Could be a lower screen resolution that full 720p (not all 720p's are alike).
I also read today that Tegra 2 720p should work in high profile, but 1080p definitely does not. But, Android itself might be limiting even 720p, so it's a crap shoot.
Just out of curiosity why do you guys want those big files on here anyway? Is it to output to a TV? I wouldn't think you would need such a high quality file to watch stuff on the G tab.

It's not about storing large files on the gtab...its more about having video portability. I keep my movies and videos on a server that I stream from my living room and bedroom. It would be ideal if I can play files on any device without having to reencode the video.
I did test 1080p files from YouTube and they did not play (high profile).
Ok, makes sense. I do the same thing using upnplay and my server. Thought you were wanting them on the tablet.

A two hour 720p movie runs ~4GB, so it's close to the limit in FAT32. And you could easily go over the limit when encoding, which would require you to break the file up. Annoying.
The problem here is that none of the vendors want to agree on a replacement file system for portable devices (wow, no surprise there). MS wants exFAT, the open source community would prefer EXT3/4, and I assume Apple would prefer HFS+.

Can't speak for everybody else, but for me I'd want to just use the video files I broadcatch from the NNTP groups. Ideally, I wouldn't want to have to reencode video to watch it, just access it directly from my media server. Standard definition avis work okay, but eventually these will not be offered and of course the HD versions look way better. Over the years it's been harder to come by a regular source of SD resolution TV Series feeds. The 720P encoded files quality are noticeable versus SD even on this smaller screen. Ideally we would get high profile 720P MKV at least to work as it seems this is what the guys doing NNTP TV Series seem to be encoding in.
What I would see happening is that a video player on the GTablet will access the files off the media server and stream, not play files directly off the local Internal SD. Regardless of where the file resides, it looks like it needs to be refined to play these files more fluidly.
I'm not saying this will be the only nor primary method of viewing video files, but having the flexibility and option is always nice. Especially when all the tvs are watching something else. ;P

Can you please share how you are thinking about doing that using movies/pictures/videos on Windows Media Center share or NFS mount.
I tried very same thing as some of my movies still in vob format or mpeg2 (home recordings of kids), tv recordings using microsoft format or streaming pics, and nothing seems to work. I was able to use upnpplay (android program in the market place) to browse my stuff on the shared drive, but can't play mpeg2, vob or other format.
does anyone know what's the best way to do this?
G Tab supports H.264 1080p main and high profiles
Detailed specs on what Audio and Video formats G Tablet supports are listed in the manual downloadable from the Viewsonic web site.
But in a few words - it does support up to 1080p, both baseline, high, and main profiles for H.264 with certain limitations for each, and MPEG4 simple profile.

My entire system is redundant. I have my windows 7 share as well as my htpc/nas running tversity, orb and audiogalaxy (music only). Everything is shared in every way. First I try just streaming the file through Windows 7 dlna, which generally works fine. I too use Upnplay. If something doesn't work (very rare) I move to looking for it through Tversity which attempts to detect the dlna device and scale it so it works. I've never needed to use Orb on the GTab since I really got everything up and running, Orb is for when I actually am on the road and want to watch sth. from my home network. PlayOn may actually work as well - it has a free mode which allows you to use it to share files on the local network using VLC codecs.
Video Playback
I'd like to add to this conversation with, I hope, clarification of how to get higher definition video playback working on the GTab.
I've tried four video files that are 720P or 1080P. None of them works well in Movies, DoubleTwist, Rockplayer, or VitalPlayer.
G Tablet, TnT 4.21, OE kernel. Market fix. Various apps.
Videos all playing from /SDCARD
Here is some more information about those videos, using Mediainfo:
Touring Car race:
720P MPEG-4 50FPS AVC ([email protected]) (CABAC / 3 ref frames)
AAC Stereo
Big Buck Bunny:
http://www.bigbuckbunny.org/index.php/download/
1080P OpenDML AVI 12Mbps 24FPS MPEG-4 Visual ([email protected])
AC-3 audio
Audi R8:
720P AVC Matroska 800Kbps 29.970FPS AVC ([email protected]) (CABAC / 2 ref frames)
AC-3 audio
Donington LG demo:
1080P BDAV M2TS 35.5Mbps 29.970fps AVC ([email protected]) (CABAC /3 ref frames)
AC-3 audio
Are all of these simply too much for me to get away with playing on the GTab? I've played most, if not all of these, using a Broadcom 70012 Crystal HD decoder card on a Dell Mini 9 (Atom N270) with few problems.
Thanks for the help.

The built in video app works fine for me, but I prefer RockPlayer.
The built in player also works fine for me. But it really only supports MP4 video files, if I understand correctly. I use Handbrake and the iPod Touch preset to encode for my Nook.
That said, I actually use Act 1 Video Player because it has the nicest 'library' view that groups by folder.
I use yxplayer, no need to encode... plays avi files like a charm.
The built-in player outperforms RockPlayer, which has some audio sync issues.
I use the iPod Touch preset in Handbrake, but I bump the resolution up to 720 x ???, turn off Anamorphic, and set a constant video bitrate of 800kbps and an audio bitrate of 80kbps.
Works well for me. Speed Racer looks gorgeous on this screen.
from my very very few experiments, i concluded that once videos are converted to mp4 (h.264 / AAC) any player is the same (uses the hardware decoding).
with videos in different formats its likely that there will be problems
i agree with nooter on using handbrake's iphone preset modifying the bitrate setting it around 800kbps (for animated movies it can be lower 600kbps should be ok). About altering the size of the movie, only for reducing it (remember the max lines in landscape is 600)
rock player works if u have the latest universal player but you need to install add block because even if you pay for it you cannot activate it
I've found that all the players avail still play back xvid/divx avi's really choppy, going to have to give handbrake a try to take advantage of the hardware decoder...
I was just able to install vplayer from the market (a few days ago it wouldn't install)... some audio sync issues but there are some cache parameters to tweak... anybody had any luck?

Same experience with playing divx/xvid files, choppy sound and 21-24fps video playback. Take that same video and run it through handbrake to convert to .mp4 and it runs great.
Where is the built in video player located? I cannot seem to find it anywhere..
I agreed with vplayer beta from the market place. It's free. It'll play most video formats. I've tested 480p and 720p mkv and both play with high speed setting. 720p mkv video is slow but 480p play fine. It's great with cifsmanager and mounted shared videos.

So, what filetype does that create? What is the Extension? MP4 or M4V? Also, are there any other settings, other than the ones listed above that you use?
I am asking these questions because I am having issues with movies encoded this way playing in the default player. It doesn't recognize the video, so it will not play.
Also, VPlayer plays them, but there is a definite audio lag once you forward to about mid-movie.
Also, as an aside, I am converting ISO files (Direct DVD rips) using HandBrake. That is how I am generating these files. I do change the extension to mp4 from handbrakes default (m4v i think).
Thanks for any help.

There is no shortcut in the App drawer (or Gallery) for the stock video player....I just click the video file (in whatever file manager you use or the Nook Library My Files tab).
Personally I use Act 1 Video player as it will present a list of videos on the SD card and Nook. Although for some reason it list videos on the Nook twice.
Sent from my Nooxus One using Tapatalk
The Act 1 app seems to be the only one that can properly sort videos. I tried the trial version, and it seems to work great, but as intuitive as the in-video touch areas may seem, I just can't get my brain dialed in to use them in practice. I think the built-in NC player works just fine, it's the video file/folder sorting that's nearly impossible to navigate once you have 20 or 30 vids on there along with a few thousand photos.
The media sorting options on Android are surprising lacking, or I just can't seem to find methods to deal with 32 gigabytes of media on this device.
I just did a bunch of conversions from some 720p MKV's. I converted them using Xilisoft video converter.
The settings I used were:
720x420
800k bitrate
44.1khz 128kbps audio
H.264 codec MP4 extension
Plays flawlessly with Rockplayer. No desync on fastforward.
The Built in player IS the best
After many attempts and reboots, I have determined that the Built-in Media player is the best player for videos encoded as specified earlier in this thread...
I tried Rock, and VPlayer beta, but both had very bad audio sync issues.
The Built-in player played all my encoded videos flawlessly. The wife LOVED watching Salt on the Nook during our road-trip. The only downside is the audio on the nook--hardly any volume. Easily solved by a good set of earphones. We are very pleased with the nook.

Check out mVideoPlayer. I haven't tried it on the Nook, but its perfect on my Galaxy S phone.
As for encoding, go with handbrake. Choose the Apple TV preset. Set resolution to custom and width to 800 (handbrake should automatically choose the correct height based on asperity ratio of source material). Set the video quality to constant at 60% (70% is the max you want for HDTV). Under audio, select the appropriate track and select aac with Prologic II or stereo as the encoding. Use the MP4 extension as to avoid issues with different t players.
You can get way more detailed on settings beyond that. It just depends on the material and the playback device. Those settings should get you outstanding video on the Nook. May have to scale back a little if the video is choppy.

After much trial and error, I have to agree with previous poster who said the best player is the built-in player with mp4 files created with the settings mentioned. The other players all had issues with controls and added nothing if the file was formatted as described.
I also had a lot of trouble getting any player to play any file at first. I think installing some of the other players added some necessary codecs. Then after a reboot, everything started to work. Hope that helps someone else avoid some frustration.
Despite a few trials like this, I love this tablet! Thank you xda devs!
Sent from my rooted Nook Color using XDA App
I'm running the free version of Rock Player. It's not exactly the cheapest app out there on the Android market, but if it works well, not a big deal.
Whenever I choose an mp4 video that I've encoded at 848x360, for example, Rock Player seems to default the widescreen video to this resolution, assuming the Nook Color scaled resolution is 1024x600, which means that a high quality widescreen rip at the smaller resolution will default launch with black bars around all 4 edges.
I noticed that the video display resizing has 3 modes,
(1) the default mode as mentioned above
(2) zoomed mode which fills the whole screen, stretching as required
(3) scaled mode which allows the widescreen video to stretch to the left and right edges properly, while maintaining a proper aspect ratio.
So the simple question is, how do I configure Rock Player to default launch video files in the mode (3) mentioned above?
Hello All,
I am running CWM and TNTlite 4.40. I am having issues playing video on it.. I tried playing the videos that it came with and some on them it would play no problem with the standard video player that it came with.. Then i tried loading my videos thru USB or microsd and it has a LAG.. I converted the video from 2GB mkv to Mp4. i used Rockplayer and it does the same thing.. The audio is fine but the video has a delay. Not sure what is going on or if it is the firmware it self. Can someone shed some light.
thanks in advance

What is your video encoded at? If it's high profile H.264 you may have issues depending on resolution (and at 2GB, I'm guessing it's not a 480p video!)
A program called MediaInfo (free) will tell you how your video is encoded - if you see anything like "[email protected]", it's too much for the Tegra 2 chip to handle. It will do [email protected] with some tweaks to settings (like no p frames). One of my other posts (shold be able to search under my profile if you're really interested) has Handbrake settings for a good 720p video encode that runs like butter and isn't a space hog either.
To be safe, at the moment I'm starting this one at Q&A; but if enough useful info is gathered, or, if the mods see it fitting, I would like to move this thread to "General".
if i'm using some farmer terms, plz feel free to correct me so that the final summary is understandable for eveybody.
So the questions are:
1. Which video/multimedia player is the best for android?
- For example which one plays the most audio/video formats,
- Which one gives you the most flexibility as for screen size, zoom, aspect ratio.
2. Which (preferably free) converter to use?
2.1 What is the maximum capability of SGSII?
- How many bitrates etc. can it handle with its mighty processor? How many bitrates and other hd settings are necessary for sgsii.
Please comment
Try dice player..not free though but u can try it for a few days before purchase.

Only an answer to #2, no experience with other than the stock player (yet).
For conversions I use AviDemux.
It's multiplatform and some people I have referred to it reacted favourable as well.
Tried to get a full movie to the SII, no succes yet. (4GiB+).
Kind of curious myself if there is a filesystem which will allow that on a memorycard and leave it usable in the SII and Windows.
No best player for sgs2 ?????? i tried so many nth seems to work fully functional !
Im media playback fan my self, but just to lazy to make guides or explain alot.
1. My favorite players from market
mVideoplayer for daily use and
Diceplayer and or Moboplayer (for rare videos that don't work with hardware decoding and need software decoder)
2.0 I use MeGUI for video conversion encoding to MKV high profile x264.
2.1 SGS2 can playback "MKV high profile x264" 720p @ 60fps and 1080p @ 30fps
I use Handbrake (freeware) to convert my HD videos to 800x448 (or whatever aspect ratio the original video is) and 1000kbps (I don't use TVout, so I don't really need the extra resolution).
Since CM7's video player doesn't support subtitles which I need, I use MoboPlayer and mVideoPlayer to play my videos.
For reference, after I watched a 20min video encoded at the above settings (brightness was at ~50%), my battery lost 3-4% of its charge, which in my opinion is pretty good.
Players that are able to show subtitle on TV screen

I've already tested both players that you mentioned above and I can't get get any subtitle on TV , just on the phone's screen. Any suggestions of players that can do what I need?
What resolution must i change 1080p video to to run it fullscreen HD on the Atrix, I tried 540x960 but that doesnt run full screen, and importing full 1080p, unsuprisingly, runs very slowly.
Thanks
What app are you using to play the videos? Also, in order to play HD videos smoothly, Tegra 2 requires Baseline profile H.264 whereas most HD videos use High profile H.264. These videos have to be re-encoded as baseline in order for playback to be smooth.
EDIT: Do you mean you get black bars on the top and bottom? What about the left and right?
im using MoboPlayer, and am getting black lines all around, so i guess its not the wrong ratio. what would re-encoding videos require on windows? i use handbreak on my mac, but i dont currently have that on me. also what would the highest resolution be that the atrix could handle well, it seems a shame to watch films like Transformers with a low quality image
thanks

Handbrake is on Windows and Mac so you're good to go there.
Using moboplayer to play.. mkv's? If you re-encode the video like above, you can use the stock video player which I guess is just called "Gallery" or "Video Player"... Otherwise, MX Video Player is capable. Both of these are able to use Tegra's hardware acceleration. I still get some stuttering on MX Video Player though so I recommend just using Gallery.
