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).
