Hi All,

I use ffmpeg command to generate audio and video stream.
ffmpeg -loglevel debug -f video4linux2 -r 30 -s 640x480 -input_format h264
-i /dev/video1 -f alsa -ar 44100 -ac 2 -i hw:0 -vcodec copy -acodec copy
http://localhost:8090/feed1.ffm

I got the stream layout :
 Stream #0:0, 0, 1/1000000: Audio: pcm_s16be, 44100 Hz, stereo, 1411 kb/s
    Stream #0:1, 0, 1/1000000: Video: h264, yuv420p, 640x480, 1/30, q=2-31,
-5 kb/s, 30 fps, 1000k tbn, 30 tbc

Can I modify the layout to
Stream 0 is video , and stream 1 is audio?
