Hello everyone,
I try to get my Terratec Grabby USB work to capture old VHS.
I compiled webcamd from port, my integrated webcam work fine when I run pwcview, but the grabby show me a green screen like no input.
I have the node in /dev :
I don't know why I have 3 video device. One of them is the webcam, the other should be the Grabby, and the last I don't know.
Anyways, The Grabby seem to be reconized :
I tried both mplayer and VLC, can't get any video.
that loop on select timeout, when I hit Ctrl-C
Any idea?
