Re: libv4l2: error dequeuing buf: Input/output error

There have been some improvements to gspca_main and gspca_pac207 recently, as well as pac207 specific improvements in libv4l2. Are you using the latest v4l-dvb and libv4l2? I get some slowdown halfway when using capture-example.c and it seems to improve when I use the latest v4l-dvb and libv4l2 from mercurial. http://linuxtv.org/hg/v4l-dvb

Hi all,

Can anyone give any clue as to why I might get this error when capturing from a PAC207 webcam? It happens after a 6-7 second delay when capturing.

I've seen this with 2.6.30.1, 2.6.30.5 and 2.6.32-rc7, however I can run the same camera on another (much faster) system using the same kernel(s) and same gspca driver and it works fine, making me think this is a timing issue.

I'm testing with the v4lgrab.c program, compiled statically against libv4l2. A quick google indicates I'm not the only one encountering the problem.
thanks,
Biff.
