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.
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.
A lot of claims have been made that the new Chromecast cannot do 60fps for YouTube videos and whilst from experience that was the case with the original Chromecast and will continue to be with the YouTube app, it is possible (kind of) to get videos to display at 60fps on the new Chromecast via screen mirroring. I say "kind of" because I have noticed frame drops and some sound sync issues every so often because the video output is not optimised. If Google wanted to, I would theorise that it would not be an issue for the YouTube app on Chromecast to run at [email protected] or even [email protected]
If you wish to verify (or rubbish) my claims, the method on how to do it is below:
You will need
- 1x Chromecast 2015;
- 1x Laptop or PC with a resolution at 1920x1080 with Google Chrome and the Google Cast (Beta) extension installed. As a junior member, I can't post a link but it's easily found on your favourite search engine using the phrase "Google Cast (Beta);
- 1x video which works at [email protected] (Sonic ones are good to give the video encoders a good test);
- (optional) video capture device which records at 60fps if you wish to show the world that it works.
Ensure your Chromecast is working, on YouTube, select a video which has a quality option of [email protected] Select the Google Cast extension (the button in the top right of the Chrome window which looks like a Chromecast button) and select options in the menu. Ensure that it is outputting at 1920x1080. Also feel free to test with the bitrate options (I set it to 10000Kbps although from experience [email protected] work between 2000-6000Kbps), ensure the "Maximum capture frame rate" is set at 60 and also ensure the "Enable frame size/rate auto-throttling" option is turned on or you'll get sound sync issues.
Now using the Google Cast extension, select the drop down arrow (don't get it to cast youtube.com otherwise you'll be stuck at [email protected]) and select the "cast this tab" option before selecting your preferred Chromecast. Now play that video and put it in full screen mode (right click and select the "Stats for Nerds" option to verify that the YouTube video is running at [email protected]).
All being well, with the aforementioned issues, it should be outputting at 60fps as opposed to the standard 30fps. Something very welcome for video game footage. Seems to work better if the tab your video is playing in on Chrome doesn't lose focus. If it does, I did find frame skipping occurred more often.
I uploaded a video to YouTube to verify the claim I made.
Hopefully Google will take note and at some point in the not too distant future, 60fps will be available on Chromecast - at least for the new ones.
So, what about the new Chromecast Ultra? Does the new Chromecast Ultra play YouTube videos at 60fps?
@tkdsl :
Saw your video review of the Chromecast Ultra:
https://youtu.be/IeuNO3K97mQ
But unfortunately you did not mention if the Chromecast Ultra plays YouTube videos at 60fps.
Can you please tell us if the Chromecast Ultra plays YouTube videos at 60fps?
And @MikeChannon :
Can you please create a proper forum for Chromecast (i.e. separate from Android TV) and create a proper sub forum for the Chromecast Ultra?

Thanks, but "looking great" = actually playing back at 60 fps?
Can you confirm that?
And would you also be able to confirm if the Chromecast Ultra plays 2160p60 YouTube videos at 60fps?
I saw in your video that your monitor apparently only supports [email protected] via HDMI. Do you happen to also possess a UHDTV that can do [email protected] so that you could test if 2160p60 YouTube videos are being played back at 60 fps?
There are lots of users on the Internet who would like to know that.

And we need this year's Chromecast at the price of last year's Chromecast .
Charging twice as much is quite a lot...
I can't find anyone else with this problem, so I decided to come here where the professionals live.
My problem is that i'm 100% sure that this is an hd phone, as I've downloaded and played HD videos before, and the default background is HD. Whenever I run the youtube application, the maximum quality that i'm allowed to choose is 480p. Any help would be appreciated.
The resolution is qHD, youtube detects itself, so we cant have 720p on youtube.

Moto E 2015 has a 960x540 resolution screen. While the phone can handle playing higher-resolution video (I'm been able to play 1080p and 720p 10bit video in MX Player with no issues), the Youtube app limits to the resolution of your screen. Wish it at least gave the option for 720p, for the greater bitrate, but alas it's limited to 480p. Unofficial Youtube apps might give you all the resolution options, but I haven't tested out any to confirm.
I know this is a 2k screen but YouTube will not allow the resolution 1080p is the highest anyone know why or a work around.?
It is some server sided crap. Try reinstalling the app or if that doesnt work use "youtube vanced" from xda. You could even set 4k there if you wanted without ads.
I can watch 1080p just fine with the normal youtube app, not sure about 1440p though
1080p max. Doesn't bother me, but not sure where the limitation comes from.
Just checked, it's the same on my Mate 10 Pro.
With youtube van Ed if you set it over 1080p you get problems at more than 30fps which is very stupid with this being a "mediapad" but in reality you can't tell too much difference on a 10 inch screen so it's not a deal breaker for me

videos on YouTube are encoded up to 1080p in H264 AVC format and higher resolutions are VP9 only. The M5 doesn't have a VP9 decoder, it can only decode H264 and H265 (odd cos these cost money to implement, but VP9 doesn't). So youtube falls back to H264 and plays that.
I think there is something wrong with the app itself.. Because if u play the same video in youtube on browser, it will show that u can play 2k with no problems.
I am facing the same problem and i cant find a way to fix it!!
