libv4l2: error dequeuing buf: Input/output error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
