[Mohamed Hnezli]

 I am trying to stream both video&audio from usbcam&mic throw ffmpeg over
ffserver I got 2 errors:

- ffmpeg seems functionning but showing "Data doesn't look like RTP
packets, make sure the RTP muxer is used" - i can connect to ffserver only
for static files

here is server.conf file:

my ffmpeg cmd is

ffmpeg -s 720x720 -f video4linux2 -i /dev/video0 -r 25 -f alsa -i hw:0
-c:v libx264 -c:a aac -strict -2 rtp://192.168.1.149:1234/test.ffm


it seems working but showing this error:

"Data doesn't look like RTP packets, make sure the RTP muxer is used"

when i stream the static files it works but when i try to play usbcam
stream throw ffplay and vlc nothing works
