29 Hi Neil,

31 I got motion "working"....
32 As it seems, it does not support h264 compressed streams. It switches
33 back the camera to YUVY, which increases the bandwidth on USB2. In
34 turn the frame rate of the recorded video dropps: The video looks
35 like awkward old-school "stop-motion" movies.
36 And audio is also missing.

38 Sorry for the bad news...

40 Best regards,
