After the recent system update my webcam: 04fc:0561 Sunplus Technology Co., Ltd Flexcam 100 stopped working properly.

The driver "gspca_spca561" is loaded automatically, but works incorrectly, when trying to use "gspca_sunplus" the camera is not recognized.

Unfortunately I did not pay attention to the driver used before I've updated to 2.6.27...

What do you mean be "works incorrectly"? The new gspca drivers only support v4l2 and don't do conversion in the driver. You need libv4l to do that (either built into your application or as LD_PRELOAD wrapper). I was going to upload that package to extra just now, but the server with the source tarball is unavailable right now.

Hmm, mplayer should support it all on its own. But you have to set some options, tv:// won't be enough. Here is what works for me: mplayer tv:// -tv driver=v4l2:noaudio:width=640:height=480:device=/dev/video0 -fps 30

Ok, I'll try libv4l, thanks!

Should be in extra now. Version 0.5.2 should hit the mirrors soon. I think it even fixes a bug with your camera, not sure.
