Hi again, I looked at the driver again, and thanks to Hans, I found you could easily lower the JPEG compression quality and stop buffer overflow. At line 2093 of build/sn9c20x.c (gspca test), there is: sd->quality = 95; Changing '95' to '80' should be enough. I will add this parameter as a video control as soon as it will be standard. Then you could adjust it with an external program as v4l2ucp. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
