Multiple Audio Streams

Denny Ferrassoli
Is there a way to convert multiple audio streams into one audio stream? (I'm
converting from MOV to FLV) Below are the streams in my video:

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':
  Duration: 00:00:36.5, start: 0.000000, bitrate: 30514 kb/s
    Stream #0.0(eng): Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s
    Stream #0.1(eng): Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s
    Stream #0.2(eng): Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s
    Stream #0.3(eng): Video: dvvideo, yuv411p, 720x480 [PAR 0:1 DAR 0:1],
29.97tb(r)
    Stream #0.4(eng): Data: tmcd / 0x64636D74

And here is the output, it seems like it's only mapping one audio stream to
the output file:

Output #0, flv, to '_video.flv':
    Stream #0.0(eng): Video: flv, yuv420p, 480x360 [PAR 0:1 DAR 0:1],
q=2-31, 600 kb/s, 27.00 tb(c)
    Stream #0.1(eng): Audio: adpcm_swf, 11025 Hz, stereo, 32 kb/s
Stream mapping:
  Stream #0.3 -> #0.0
  Stream #0.0 -> #0.1


Thanks

Not possible, you have to demux the streams, use an external app (like
sox) to mix them them remux audio and video. Note the difference between
'mux'and 'mix'!

BTW *don't* selectively edit the output messages, post them complete.
