Merge Video and Audio Streams to SWF File

This section provides a tutorial example on how to merge a video stream SWF file and an audio stream SWF file into a single SWF file. '-map' option used twice to specify video and audio streams into the output file.

I am sure now you want to know how to merge a video stream and an audio stream into a single SWF file. Here is the "ffmpeg" command to do this:

C:\herong>\local\ffmpeg\bin\ffmpeg 
   -i video_input.swf -i audio_input.swf 
   -map 0:0 -map 1:0 output.swf

The above command uses "-map 0:0" to specify the first stream (video stream) of the first input file to be mapped to the output file. And it uses "-map 1:0" to specify the first stream (audio stream) of the second input file to be mapped to the output file at the same time.

Let's try it on our sample SWF file, Anchor_and_Spider_Man.swf:

C:\herong>\local\ffmpeg\bin\ffmpeg 
   -i Video_with_No_Audio.swf -i Audio_with_No_Video.swf 
   -map 0:0 -map 1:0 Video_and_Audio.swf

Input #0, swf, from 'Video_with_No_Audio.swf':
 Duration: N/A, start: 0.000000, bitrate: N/A
  Stream #0:0: Video: flv1, yuv420p, 416x240, 25 fps, 25 tbr, 25 tbn

Input #1, swf, from 'Audio_with_No_Video.swf':
 Duration: 00:00:40.61, bitrate: 128 kb/s
  Stream #1:0: Audio: mp3, 44100 Hz, stereo, s16p, 128 kb/s

Output #0, swf, to 'Video_and_Audio.swf':
 Metadata:
  encoder         : Lavf55.40.100
 Stream #0:0: Video: flv1 (flv), yuv420p, 416x240, q=2-31, 200 kb/s, 
              25 fps, 90k tbn, 25 tbc
  Metadata:
   encoder         : Lavc55.63.100 flv
 Stream #0:1: Audio: mp3 (libmp3lame), 44100 Hz, stereo, s16p
  Metadata:
   encoder         : Lavc55.63.100 libmp3lame

Stream mapping:
  Stream #0:0 -> #0:0 (flv -> flv)
  Stream #1:0 -> #0:1 (mp3 -> libmp3lame)
