What steps will reproduce the problem?
1. Build and/or install v4lsink (deb package or mercurial) (I have modified the
source by overwriting video1 to video0 in gst-v4lsink-loopback.vala)
2. Build and install v4l2loopback (modprobe v4l2loopback)
3. v4lsink 'filesrc location=1.yuv ! videoparse width=160 height=120 !
V4l2SinkLoopback'
4. mplayer tv:// -tv device=/dev/video0
What is the expected output? What do you see instead?
I expect the yuv video to show up in mplayer's screen but I get:
"v4l2: ioctl get format failed: Invalid argument
v4l2: ioctl set mute failed: Invalid argument
v4l2: 0 frames successfully processed, 0 frames dropped."
v4lsink shows no error:

Please provide any additional information below.
./v4lsink 'filesrc location=1.yuv ! videoparse width=160 height=120 !
xvimagesink'
works perfectly. I see the movie in an X11 window.
./v4lsink 'filesrc location=1.yuv ! videoparse width=160 height=120 ! filesink
location=2.yuv'
works as well. Movie saved to 2.yuv.
