I am trying to record videos with vlc from USB webcam from A20 humming board
The command i used to rercord with vlc
Enter code here...vlc v4l2:///dev/video0 :v4l2-standard=
:input-slave=alsa://hw:0,0 :v4l-caching=300
--sout="#transcode{vcodec=h264,vb=0,,scale=0,width=640,height=480,acodec=mpga,ab=128,channels=1,samplerate=44100}:standard{access=file,mux=mp4,dst=output00.mp4}"
Then it shows the following log
VLC media player 2.0.5 Twoflower (revision 11d59d1)
[0x19e88f0] main libvlc: Running vlc with the default interface. Use 'cvlc'
to use vlc without interface.
