I'm trying to copy the first minute of an mp4 file, but getting a strange result in which I try to play the file output from ffmpeg and the first 5 secs are missing!
I have tried using the following command:
ffmpeg -i The\ Big\ Fight\ \(1972\).mp4 -ss 0 -t 30 -c copy fight.mp4

as well as this command:
ffmpeg -i The\ Big\ Fight\ \(1972\).mp4 -acodec copy -vcodec copy -ss 0 -t 00:0:30 fight.mp4

both result in the video starting to play at 05s, and nothing exisiting prior to that 05s
