The scanning works fine, but when playing the video, it seems like that the data fed to players are problematic. I tried mplayer/vlc/mythtv and all of them show similar problems: the video is mangled (with correct blocks here and there) and the audio is intermittent. mplayer says a52 decoding error and mpeg2 decoding error. It's not a signal problem, because it works flawlessly with older versions of webcamd. I tried various versions of webcamd and here is the result: 322747 (3.11.0.2) does not work 322982 (3.10.0.7) does not work 312661 (3.9.0.5) works 310291 (3.9.0.1) works 300026 (3.6.0.1) works 277800 (3.0.0.1) works So it seems like that there is a regression between 3.9.0.5 and 3.10.0.7. I'm willing to help with debugging this problem. My system is a recent current under amd64. -- Cheers, Henry
