Guest Theopulus Posted April 14, 2011 Report Posted April 14, 2011 I've been messing aroud with Arista Transcoder (Ubuntu) to get a 720p video file playing correctly on my Vega, but I can't I've tried to reduce fps to 23.97, reduce height to 576 Can anyone tell me which settings work best with the stock player? I suppose that a Tegra 2 machine should be able to playback decently such files

I suppose that a Tegra 2 machine should be able to playback decently such files You mean the playback is slow? or there is some other problem? For my tests I used the the video files from here: http://www.bigbuckbunny.org/index.php/download/ as you can see the MP4 videos on there have AC3 surround sound, the default media player couldn't play the sound (just silent video), I tried the VLC player and it worked fine, i.e., the sound and picture were synced. I tried the 1280x720 resolution and running 'top' using ADB shows just about 30% of the CPU time is taken by the player (decoder): When playing the OGG file the sound was out of sync even with 420p videos. Why don't you use ffmpeg? This is the first time I heard of Arista Transcoder.

I've tried the vplayer seems good, but using Bluetooth headphone there seems to be an audio lag (variable) I'm using me.abitno.vplayer.t.v0.8.2.zip The point about FFmpeg is valid if there are working sets of parameters for FFmpeg that work well for the Vega with specific players perhaps this could be added to Vtools I'm happy to document. Arista is open source :) http://www.transcoder.org/ linux binaries and GUI and has a range of presets http://www.transcoder.org/presets/ here is a good comparison http://maketecheasier.com/encode-webm-vide...inux/2011/01/26 I've been using a range of video sources and the playback seems to be generally good (though not perfect) but it is improving. Which version of VLC are people using there many in Market some free some paid. I loaded one VLC Stream and Convert but once installed it does not seem to do much: Clicking a video file in file explorer just shows Movies and Vplayer. I'm happy to run with a range of video players (depending on content) Edited April 15, 2011 by FrownBreaker

I'm happy to run with a range of video players (depending on content) . . I havee been have problem with slow frame rates, lag and pixelization.. a friend said i should try vplayer but to be honest no matter what settings i used the issues with playback were far worse then the standard media player that comes on the vega. I should say that 720p mkv files play fine so long as the file size is less then 500mb, anymore then this and the vega struggle to decode the data..
