I actually have a Dazzle DVC100 which I'd forgotten about so had to go hunting for it. I actually meant lsusb, but I see the analogue component of em28xx is causing you problems.

If so: what is the bottleneck? If not: I'd be interested in solving this problem with you.Ĭode: Select all MEncoder SVN-r35920-4.7.2 (C) 2000-2013 MPlayer TeamĬapabilities: video capture VBI capture device audio read/write streaming Here's the problem: The captured video is basically a green image with working sound (you can only hear the wind and transmission noise (I'm working on that) since no birds have settled yet). For those who are not able to have a look at the problem live, I provided an example image. Keep in mind, that the system's availability depends on sunrise, sunset (CEST), insolation, and whether our wireless is enabled or not. You can have a look at the results so far here: All devices are powered by a photo-voltaic panel which charges a 6.6 Ah akku. Using a Terratec Grabby USB adapter, my Pi tries to capture the signals (available through the v4l2 driver) for a certain amount of time (using mencoder) and provide the recording over HTTP. The receiver provides the analog video and audio signal over cinch. The system consists of an infrared camera which transmits video and audio data from the birdhouse over 2.4 GHz to a receiver. For the coming bird breeding seasion, I'v set up an "autonomous bird watching system" with which one can have a look into our birdhouse.
