All,<br><br>I am trying to capture/stream video from a Video4Linux compatible<br>capture card, and audio from an on-board microphone input using a x86<br>based Intel motherboard, linux OS (kernel 2.6.23-rc), and VLC version
0.8.6c<br><br>Here is the command line I use for capturing video:<br><br>vlc -vvv v4l:// :v4l-vdev="/dev/video0" :v4l-norm=1 :v4l-width=320<br>:v4l-height=240 :v4l-fps=15 :v4l-audio=2 --sout<br>'#duplicate{dst="transcode{vcodec=mp4v, vb=1024, sfilter=time,
<br>soverlay}:std{access=udp, mux=ts, dst=<a href="http://192.168.200.10:1235">192.168.200.10:1235</a>}"}'<br><br>This works perfectly, and video is received at the destination.<br><br>For audio,<br><br>vlc -vvv v4l:// :v4l-adev="/dev/audio" :v4l-audio=2 --sout
<br>'#duplicate{dst="transcode{acodec=mp4a, ab=192}:std{access=udp, mux=ts,<br>dst=<a href="http://192.168.200.10:1235">192.168.200.10:1235</a>}"}'<br><br>This works just fine, too. Audio is received at the destination.
<br><br>However, when I try to do both simultaneously, I only receive audio, but<br>no video, i.e.<br><br>vlc -vvv v4l:// :v4l-adev="/dev/audio" :v4l-vdev="/dev/video0"<br>:v4l-norm=1 :v4l-width=320 :v4l-height=240 :v4l-fps=15 :v4l-audio=2
<br>--sout '#duplicate{dst="transcode{vcodec=mp4v, vb=1024, acodec=mpga,<br>ab=192, sfilter=time, soverlay, channels=2, audio-sync}:std{access=udp,<br>mux=ts, dst=<a href="http://192.168.200.10:1235">192.168.200.10:1235
</a>}"}'<br><br>Could somebody help me with this? I must be missing something,<br><br>Thanks in advance !<br><br>GA<br><br>Here is the debug output for the audio/video combo case:<br><br>*****<br>[00000001] main private debug: checking builtin modules
