[MPlayer-users] v4l2 output driver: outputting to a v4lvd device

[Brian Jedsen]

Does anyone know if it's possible to use mplayer's v4l2 output driver to 
feed video into a v4l2 loopback driver? I compiled and installed the 
v4l2vd driver (http://v4l2vd.sourceforge.net/), but so far have not been 
able to get mplayer's v4l2 output driver to write to the appropriate 
v4l2vd output device. I'm using this command to capture video from my 
web camera:
mplayer tv:// -tv 
driver=v4l2:device=/dev/video0:width=320:height=240:fps=15 -vf 
scale=128:96 -vo driver=v4l2:device=/dev/video6
and mplayer fails with the error "Error opening/initializing the 
selected video_out (-vo) device." I've also tried the subversion 
snapshot of mplayer to no avail. Anyone have any insight into this 
problem? Thanks.
