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.
Will the evo 3D save the 3D pictures as Jpeg, or is there some kind of 3D filetype out there already? Also, what about 3D video? Mp4? (I know people might not know this yet, since it's not released)
On video, I dont know what it uses, but I supplied what it can play. If I had to guess I'd go with MP4 so that it can be watched on other devices as well being that it is very popular.
Photo Format: JPG
Video Formats: MP4/Xvid/H.263/H.264/WMV player

I had the optimus 3d for a week and the pictures were saved as .jps (jpeg stereoscopic, i think) and the videos were saved as .mp4
so even though it's stereoscopic, these are regular old Jpegs that can be displayed in 2D, on any display with any software that handles typical Jpegs? And does the same go for video?
If its anything like my 3DS it makes 2 copies when you take one pic, one is a .jpg and the other is .mpo. The .mpo is only viewable on 3D screens and you use the normal .jpg for MMS, Facebook, and stuff like that. But nobody knows.
I've been informed by HTC the video is mp4 with a 3D header (side by side)
Photos are JPS (industry standard, Stereo JPEG) which is basically a renamed JPEG file with both images side by side, right eye on the left, left on the right (cross eye)
you can rename them to view on a PC but you will see both photos at the same time.
Anyone know of a fairly automated or easy way to convert wmv or other 3d video to play in 3d on the evo? Ive been playing with handbrake and a few others without success. Vids play, but show 2 screens side-by-side. Somehow, something is missing that tells the Evo movie player to play as 3d. Ideas?
Ok nevermind! Solved my own issue. Handbrake seems to work fine. Use guide found here: http://www.knowyourcell.com/htc/htc...fer_them_to_the_htc_evo_3d.html#comments_form
Start playing with vid player. While movie is playing, hit menu button. Option to play in 3D\2D appears. Select 3d and continue playing vid! ImDumbSometimes...
I'm curious about this myself.
So the movies you are converting, what format are they in? MKV or some other file type?
Handbrake keeps their formatting (2 videos side-by-side)?
Thanks for any help.

Yes, Handbrake will keep the files in side-by-side. Following the instructions in the knowyourcell linke, you'll typically be converting a MKV into an MP4. But your Gallery app is smart enough that when you watch the video and hit settings-->3D, it'll merge the screens.
HOWEVER, I was never able to get the Handbrake solution to give me good audio. So I tried Freemake and it was very successful and a little faster I think. Here's my writeup:
****TWO PRELIMINARY NOTE: (1) Please note that this is only to be used for 3D video files that you OWN THE RIGHT TO USE. (2) This guide will be most useful to those trying to convert a .MKV file, which is a type of 3D video file that is always (in my experience) "side-by-side" (technically called HALF side-by-side or half-sbs) meaning if you were to play the file on a non-3D device it would simply show two identical videos running side by side. It's THIS kind of 3D file that I've had success with so far; I've had a harder time finding solutions with "top/bottom" (also called "over under" 3D files where one image is ABOVE the other.******
Ok, now that that's out of the way, let's get started
For Starters, You'll Need:
A) The 3D file you want to view on your HTC Evo 3D
B) A connection to the internet
C) Your HTC Evo 3D (of course )
D) Your USB cable to connect your EVO 3D to your computer (this came with the phone)
Next, Your computer will need some Video Conversion Software:
DOWNLOAD: I've heard of several different programs working, but my favorite by far has been Freemake Video Converter, which you can download on your computer by going here by clicking the green "DOWNLOAD" button in the top-right corner of the page. (Once you click the DOWNLOAD button, you'll be sent to CNET.com, a very trusted tech news and download site, so you know it's a safe place to download a file!).
Launch: Launch your freshly-downloaded Freemake Video Converter.
We're halfway done!
Find Files to Convert: Now that the program is open, click either the "+ Video" or "+DVD" button in order to browse your hard drive for the 3D movies you want to make viewable on your EVO 3D. Double click on them to add them to your queue. (Remember, these should be side-by-side 3D videos--probably with file extension .MKV)
Notice how each file you double click on simple gets added to the list (queue) in the big white middle of the program. So Freemake automatically builds a queue and will let you convert ALL your files with one click later on! However, if you just want to convert one file, find it, double click it to put it in your queue, and move on
Once you've lined up your files, go to the bottom of Freemake and click "To Android."
Click the drop-down menu under "Preset", go all the way to the bottom and click "Add Your Preset" (or just click the green plus sign)
Name your new preset "Evo 3D" or something you'll remember, then apply these settings:
- Frame size: size up to
- Width: 960
- Height: 540
-Adjustment: Original
-Video Codec: H.264
-Frame Rate: Original
-Bitrate Type: Custom
-Bitrate (Kbps): 1500
Then for audio, click the "Custom Audio" button and use these settings:
-Audio Codec: AAC
-Channels: Stereo
-Sample Rate: 48000 Hz
-Bitrate: 256
Click OK and it should save your new preset. Now choose the file path that you want to save your new files to (note: you can't change the file names of your converted files at this point). Note that this conversion will leave your original file INTACT and in their ORIGINAL place and simply make converted COPIES.
Click CONVERT and THAT'S IT! You're Done! Check the status bar, but after about 20-50 minutes a regular movie should be done.
Now that conversion is complete:
-Plug in your Evo 3D, access the SD card from your PC, and copy/paste the newly converted file onto your SD card (What most of us do is create a new folder on the SD card called "Video" and then place all our converted files here).
-Use GALLERY to watch your movies--it should find the files automatically. When watching, it will usually start by playing the file as two images side by side. Just make the video fullscreen, THEN hit the options button and choose "3D", confirm, and there you go!
**NOTE: Not all of the above steps/settings may be necessary, and there are probably some great ways to improve it...but this way should get you a pretty good, very cool 3D video on your phone! Although don't forget the end result can never be better than what you start with!**
Thanks again. After I initially replied, I found both your tutorial threads on SU & XDA.
You rock dude. I noticed Handbrake literally made my computer slow to a crawl (100% CPU on multiple cores). I read that the other software you mention actually uses the GPU, which is better IMO.
I used the settings you provided in freemake. They work but I would recommend using a higher bitrate. The Evo 3d records at 1280x720 at 5200kbps at 29fps. At 1500 they are choppy and in some areas show artifacts. You might want to up the bitrate. The difference between the resolution wasn't noticed. Also lowering the frame rate helps save some space.
what is the term for a video file with side by side video? I'm not having much luck finding any sample videos except on youtube and I wanna play with 3D more than I do lol

Hey guys.... Thought I'd pick your brains for a moment. I'll try to be as concise as I can but it'll seem a little long-winded lol. Here goes:
I was messing around with some features on my hubby's Samsung Smart TV - I noticed that when I mess around with the bluetooth stuff on my Rezound, the TV will show up as a discoverable device, so I paired the two.
I remembered that I have a few videos on my phone so I tried to send them via bluetooth to the TV - I go to my 'gallery' and select the video I want and in the top-right of the phone's screen is the "output" option. I select it and there's the TV available... I chose the TV to send the video to... The TV itself then goes black and a "loading" screen appears on it but then it displays an error message saying it cannot play the selected file format. More specifically, it states something like "Codec not supported." (I'm assuming it means mp4s.)
Now, this only happens with the videos I have recorded from my phone but it WILL work with the videos that were preloaded by Verizon when I got the phone. Those are mp4s as well.
Has anyone ever tried it or does anyone know how to get this to work? It certainly seems like it should work since the preloaded Verizon videos work. I did notice that on my phone, the TV is listed as a "wifi player" but I'm not sure what that has to do with it.
Any thoughts? Thanks!

I pulled two videos off the phone and looked at their specs in gspot. While they are both apparently using mp4 containers, they are encoded differently, you can see it on my screenshot showing the specs. I'm not really familiar with the details/specs of the codecs but you would probably need to convert it for your TV to be able to play it. The one I shot using the phone is a .3gp where as the Verizon supplied one is not. According to Wikipedia 3GP was created for phones and they are using the .mp4 file extension for them.
Technical details
Relations between ISO Base Media File Format, MP4 File Format, 3GPP file format and 3GPP2 file format. Based on the 3GPP2 technical specification published on 18 May 2007.[7]
The 3GP and 3G2 file formats are both structurally based on the ISO base media file format defined in ISO/IEC 14496-12 - MPEG-4 Part 12,[8][9][10] but older versions of the 3GP file format did not use some of its features.[7] 3GP and 3G2 are container formats similar to MPEG-4 Part 14 (MP4), which is also based on MPEG-4 Part 12. The 3GP and 3G2 file format were designed to decrease storage and bandwidth requirements in order to accommodate mobile phones.
3GP and 3G2 are similar standards, but with some differences:
3GPP file format was designed for GSM-based Phones and may have the filename extension .3gp
3GPP2 file format was designed for CDMA-based Phones and may have the filename extension .3g2
Some cell phones use the .mp4 extension for 3GP video.

The frame rate is also different. The LMFAO video from Verizon is 23.98 while the one created on the phone is 30.
The output feature you used relies on the DLNA spec and WiFi. DLNA allows you to play media from one device to another as long as the receiving device supports the media. You television probably supports .mp4 but not .3g2

I have a HUAWEI g300, and while the quality of still images taken with the camera are great, video quality is awful. Or, to be more specific, the audio that goes with the video is very poor.
I believe that this may be due to the file format of the video.
For this reason, I would be interested to know whether there are any ways to change the file format which videos are recorded in. Are there any alternative camera apps that are any good, which ideally allow the user to select their own file format? My device is rooted btw.
