I have played other avi files on OpenELEC with success, but when I try playing certain ones, the video doesn't play - all I can hear is the sound playing in the background of the folder explorer.
I got some basic information about the video file using ffmpeg:
Input #0, avi, from 'myvideo.avi':
Duration: 00:58:32.84, start: 0.000000, bitrate: 708 kb/s
Stream #0:0: Video: msmpeg4v3 (DIV3 / 0x33564944), yuv420p, 720x576, 25 fps, 25 tbr, 25 tbn, 25 tbc
Metadata:
title : Videostream
Stream #0:1: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 128 kb/s
Metadata:
title : Audiostream 1
But I don't know much about video encoding, so perhaps someone could point me in the right direction as to how to troubleshoot this issue.
