Player support of the PAR flag

Error · 7th October 2007, 06:35

Which players support the PAR flag when muxing AVC video into an mp4? I encoded a video as 720:480 specifying the PAR as 10:11 (4:3) with mp4 box. The only player ive noticed that displays everything exactly correct is vlc. Is there a special way to make it so that all of the players that decode with FFDShow display the video correctly?

did you check the options "set pixel aspect ratio in media files" and "allow output format changes during playback" in ffdshow's output field?

and try a different video renderer, because overlay mixer ignores the par flag (at least for avi files)....

The problem is probably with ffdshow, not with the players. Use CoreAVC instead.
