Hi All, I am using ffmpeg for chopping media file with following commands. ffmpeg -ss 00:00:10 -t 00:00:20 -i miami.mpg -target svcd test1.mpg It chops the media correctly but it changes the resolution of output file. and if i try to check statics of out put media file in windows media player it doesnt show statics. Does anybody has faced this problem? Thanks in advance. ffmpeg tired progrmmer
