[FFmpeg-user] 3gp file without moov atom

[David Overcash]

Depending on the way the media is encoded, you may have success if you first
do a strict copy to essentially re-mux the file:

ffmpeg -i infile.3gp -vcodec copy -acodec copy outfile.3gp

Then take outfile.3gp and encode it as you were trying to originally.

Cheers,
David
