Split Video Stream Out of SWF File
This section provides a tutorial example on how to split the video stream out of a stream SMF file. '-map 0:1' option is used to select the second stream (video stream) of the first input file into the output file.
After splitting the audio stream out of the SWF file, you may want to split the video stream out too. This can also be done easily with the "ffmpeg" command:
C:\herong>\local\ffmpeg\bin\ffmpeg -i input.swf -map 0:1 output.swf
The above command uses "-map 0:1" to specify the second stream (video stream) of the first input file to be mapped to the output file.
Let's try it on our sample SWF file, Anchor_and_Spider_Man.swf:
C:\herong>\local\ffmpeg\bin\ffmpeg -i Anchor_and_Spider_Man.swf
-map 0:1 Video_with_No_Audio.swf
Input #0, swf, from 'Anchor_and_Spider_Man.swf':

Stream #0:0: Audio: mp3, 44100 Hz, stereo, s16p, 128 kb/s
Stream #0:1: Video: flv1, yuv420p, 416x240, 25 fps, 25 tbr, 25 tbn
Output #0, swf, to 'Video_with_No_Audio.swf':

Check the output file with "swfdump" command from SWFTools first:

The "swfdump" result looks good. Now enjoy the video without any music:
