Public bug reported:
Binary package hint: linux-image-2.6.27-4-generic
The module loads and seems to detect my camera, but the indicator light
on the camera no longer flashes when it is detected. /dev/video0 is
created for the camera, but does not return frames correctly.
>From various programs:
========================
cheese 2.24.0:
"Stream contains no data"
========================
VLC 0.8.6h Janus:
[00000300] v4l demuxer error: failed syncing new frame
[00000300] v4l demuxer error: failed capturing new frame
[... repeat last, ad infinitum ...]
========================
If I cat /dev/video0, the camera indicator light comes on, and binary
data comes out.
========================
mplayer tv:// -tv driver=v4l:device=/dev/video0:width=640:height=480
Indicator light goes on, scrambled video is returned (but it's
definitely video and not just arbitrary noise, but i appear more than
once in the frame, and there is a grid of green blobs, as well as
smaller black dots)

TV file format detected.
Selected driver: v4l

As the V4L1 compatibility layer is broken, this may not work.
If you encounter any problems, use driver=v4l2 instead.
