Also you should use a more recent version of ffmpeg, and this kind of ff* tool question belongs more properly to ffmpeg-user rather than to libav-user. BTW why so many newlines in your message? They make its readability worst... [...] Hope that helps, regards. _______________________________________________ Thanks very much. Yes that was my first post and Outlook added the extra lines. I've already been asked to move it to ffmpeg-user so I will do that. I still don't understand "where" to run that command, and what *exact* command to run, but thanks all the same - I'll ask it in the other group. _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
