I was trying to convert ogv video to avi using ffmpeg. It does convert without any error but the output video seems to be corrupt. Does not matter which format I convert it to, out put is same as shown in screenshot.
ffmpeg command :
ffmpeg -i original.ogv -sameq converted.avi
ffmpeg version : 0.7
ubuntu : 11.10 - 64 bit
