Hi, I have a Labtec Webcam 2200 and I have problems with the image quality with Linux 2.6.31 + libv4l 0.6.1. I made some experiments and stored each captured image as raw data and when libv4l was able to convert then I also stored the result as bmp. You can find my results at http://v4l-test.sourceforge.net/results/test-20090911/index.html There are three types of problems: a) Sometimes the picture contains a 8x8 pixel error, like in image #9 http://v4l-test.sourceforge.net/results/test-20090911/index.html#img00009 b) Sometimes the brightness of the half picture is changed, like in images #7, #36 and #37 http://v4l-test.sourceforge.net/results/test-20090911/index.html#img00007 http://v4l-test.sourceforge.net/results/test-20090911/index.html#img00036 http://v4l-test.sourceforge.net/results/test-20090911/index.html#img00037 c) Sometimes the libv4l cannot convert the raw image and the errno is set to EAGAIN (11), for example image #1, #2 and #3 Do you know how can I fix these problems?
