Hey
I'm no expert with these things but I'm trying to get a mkv 720p file I downloaded to work on my Sony ericsson Arc. Rather than re-encode (takes ages!) I use a program called gotsent, that repackages the MKV into an MP4 that the phone can then play. Sometimes this works, and phones plays the file flawlessly, other times it fails to play. I use VLC media properties to get the information about the files. Two files the phone plays flawlessly. One already converted as it's a HD mp4 trailer from the web and the other a SD MKV that I
converted.
Fast Furious Trailer works

Does anybody know what is going wrong and why the third file refuses to play?
Thanks for any help.

Try MoboPlayer, it's i thought free on the market. ;0
+1 for Mobo player
Thanks for the advise. However, I have tried Moboplayer, QQplayer, rock player. I find that these will all play HD files that the preinstalled player does well. However, MKV, convter MKV to MP4, the player will render using cpu only, and thus stutter.
I really belittled by how two files, looking identical in their properties, one if playing fine and the other is failing.
It is really an important feature for me, as the HDMI port and HD files will make an ideal media player/network streamer.
Cheers
As far as 720p/1080p mkv's are concerned only Samsung galaxy s1(720p) n s2 n their top end wave models can do it!

Hi. I do know this and willing to sell my Arc to get a Galaxy s2 but the Arc is capable of hardware accelarated mp4 video.
Please read my original post. I'm not trying to play Mkv's on the device, but MP4, which has been converted from MKV H264. Some files play others will not, but their properties look identical.
i think I may have more luck asking in an encoding video sort of forum? Any of you know another forum where I may find someone who could answer my question?

u gotta be kidding lol
*Edit- Try muxing the mp4 where Stream 0 is video and Stream 1 is audio. It may be as simple as that...
if not,
Can you post the full media info for the offending file?
Look especially for Format Profile and Format settings, ReFrames. If either of these are too high that may be your problem. Format Profile should be [email protected] or lower and ReFrames should be 8 or less (I think). Even PS3 and some other devices will not play videos outside those parameters. The professionally encoded stuff will work 'cause they know this and make it work on all devices. "Other" encoders usually try to do the same but some ignore it. You can change the Profile Level without reencoding but not the ReFrames.
The only thing I can think of other than that is if the bitrate is much higher than the one that works.
I've been trying to find the best encoding settings for HD/720p H.264 video for G Tablet with Handbrake and I'm not having much luck. I've followed this article for Notion's tablet (since its also a Tegra 2 tablet) and while the picture is great the playback is jittery. I tried lowing the RF (under Constant Quality) to 25 but it produces the same jitters.
Changing the video codec from H.264 to MPEG-4 (FFmpeg) actually produces little to no playback issues but the picture quality isn't as great (its still good though), but I prefer to use H.264.
Any one have any luck encoding HD H.264 video for their G Tablet? If so, can you share your settings?
Thanks in advance
P.S. - I'm running VEGAn-Tab 5.1.1 and using VPlayer, RockPlayer and QQPlayer to play back the videos (they're all suffering from jittery playback).

Hi,
I bought one of these tablets just yesterday - 16GB version - and so far I'm extremely pleased with it! Typing is a breeze, image quality is superb, gaming is pretty decent even for 3D, I bought Riptide GP after upgrading Honeycomb to 3.2, but I'm having issues with HD mkv playback.
Basically, watching 720p or 480p even (anime mkv files) I get jerky video playback when the movie player is set to HW mode. The jerks are subtle and steady, but mostly noticeable especially on panning scenes. If I change the player settings to SW or Fast SW, playback is smooth but slightly less quality there (but totally fine though). I've tried several players other than the built-in video player and results are the same.
HD flash plays OK, so I don't think this is a hardware performance issue, probably some HW / codec compatibility issue....
Can anyone else confirm this? Horriblesubs releases (Naruto Shippuuden / Fairy Tail).
SD xvid releases play just fine, both HW and SW settings on the player.
Better .h264 codec support perhaps?
(apparently, not .h264!)
Oh, and quite pleased with the fact that video files can in fact be played directly from the SD card, without having to copy them to the internal memory storage!
I tried posting from the XDA free app in the Market, but somehow, it crashes everytime I try to post from it, so I'm using the android browser - already submitted a report.

I am having the same problem you described? Is this typical on all android tablets?
Looks like i'll need to convert unfortunately... I wonder if there is an app for that.
Unless it is a codec issue and there is an alternative codec or fix..
I'm curious, do you feel the quality between HW mode and either SW mode available to be that worse? I'm using SW for now on these particular files, I was thinking about converting the files original formats but SW still seems pretty good I think! I will try to snapshot the differences and post them here!
Hadn't noticed before, the tablet comes with 3 HD sample videos inside all play just fine, no jerks - seems more and more like a specific codec compatibility issue with tegra possibly, to me...
A software issue. I can play videos fine on my Jetstream and Ipad2 which play badly on the tablet S.
So it isn't an android issue.
For MKV playback try DicePlayer and install the Diceplayer plugin for tegra.
Try the trial version to see it meets your requirements (before buying).
----- snip -----
Diceplayer uses HW video decoder.
It use HW video decoder at various containers and audio codecs combination. ( H.264/AC-3/MKV, H.264/DTS/MKV , H.264/AAC/MOV )

Tried it, perfect playback with the plugin - bought it already, many thanks!
yeah DicePlayer indeed the best HW accelerated player in the market... support MKV, AC3 audio codec, subs... wooot

+1 I tried out MX player too but found that DicePlayer had smoother playback.
Working container / video / audio combo and easy conversion
I've tested several combinations of container / video / audio formats with several players. First of all, I didn't notice any significant differences in playback quality between the players I tried, but I might not have tried Dice player for all of the combos.
I did try MX Video Player, mVideoPlayer, MoboPlayer and BS Player Lite, with a 720p h264 encoded video track at about 3000 kbps. For all players, I found the SW decoding modes to insufferably slow and jerky - I assume a lower bitrate in the video track might fix that. Per hardware acceleration, the video always played fine (when it played at all, see format details below).
These combos did NOT work:
mkv/mp4 container, h264 encoded video, mp3 audio
mkv container, h264 encoded video, ac3 audio (plays the video hw accelerated, but doesn't play the sound at all)
mkv container, h264 encoded video, aac audio
The only combo that did work flawlessly was this:
mp4 container, h264 encoded video, aac audio
I now had the problem that my standard video encoding tool, handbrake, cannot transcode files without also recoding the video file - and why would I want to recode the video when usually it's a h264 encoded video that will play with the right container & audio? The easiest way to transcode such a file is to use ffmpeg - I did this under linux, but it should work the same for Windows:
Code:
ffmpeg -i INPUTFILE.mkv -vcodec copy -acodec libfaac -ab 160k -ar 48000 -async 48000 OUTPUTFILE.mp4
I couldn't figure out a way to easily transcode mkv files where the video track has a variable bitrate (VFR) - I had to recode those with handbrake. If anyone has a simpler method that doesn't involve avisynth / is available for linux, I'd be happy to hear it.
DicePlayer rocks. I tried various apps but only did DicePlayer works. Tested with a 1080 h.264 movie and the quality was STUNNING! Definitely worth the money
By the way, Honey does not support H.264 natively so most of the players out there won't work

Thanks for the heads up and for the good news! Downloading now!
I use Xilisoft to convert movies to MP4. I have done a few for this device. They look smooth most of the time but if the movie has alot of action in a scene the picture gets somewhat pixelated.
I have converted to the correct screen size and aspect ratio. Bit rate at 1200 and FPS at 29.97.
Any idea what the optimum settings would be for this device?
im not convert videos...
I use MX Video and i watch all formats (avi, mpeg, rmvb).
Last movie (yesteday), i see Farenheint 9-11, bitrate was 720 and very good image.
So im wanting to know if anyone can point me in the right direction here. I want to develop a codec for android devices that supports all of the following:
Video codec
H263
H264
H265
Vp8
Vp9
Mpeg 4
Audio codecs (including all available audio channels in said formats)
Aac
Ac3
Dts
Dts-hd
True hd
Frame rates
All frame rates up to 60 including 23.976 which is default to all bluray films.
So i know android does support most of the video codecs by default but not the audio codecs. And as for the frame rate i know 30 is supported but not sure about anything else. I see this typically used on more devices such as rokus or nvidia shields and downloaded via the android app store.
Nobody?
