Convert File Format with "ffmpeg" Command
This section provides a tutorial example on how to use the FFmpeg 'ffmpeg' command to convert multimedia file from MPEG4 format to SWF format and other formats.
The main command of the "FFmpeg" package is the "ffmpeg" command, which can be used to convert a movie file from MPEG4 format to SWF format. Again let's use the MPEG4 file, Tony_reel_2009_512kb.mp4, downloaded in the previous tutorial as an example.
C:\herong>\local\ffmpeg\bin\ffmpeg -f mp4 -i Tony_reelshow_2009_512kb.mp4 -f swf Tony_reelshow_2009_512kb.swf ... Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Tony_reelshow_2009_512kb.mp4' ...
