Hello Hans,

Yes, I have qt4. I got your tree and the qv4l2 generation is OK.

I could change the controls of my webcam (but, indeed, the JPEG
parameters).

Little problem: if I directly do 'start capture', the program loops
displaying the single word: 'dqbuf'.

Otherwise, streaming works fine, but the CPU load is heavy: 85%
(vm: 40Mb) versus 60% with gtk+ (vm: 15Mb) and 8% with vlc (vm: 137Mb).

Regards.
