Green Output from USB Capture on Raspberry Pi

Question

See also support question 2010x 05x 10x 101207. I also have a green screen with time stamp on the Raspberry Pi. I am seeing the same output in vlc on that machine. I have two ex28xx devices, an Easycap DC-60 and a kworld USB2800, both check out ok on a debian laptop.

I'm using the latest em28xx driver from linuxtv.org

Answer

Michael , not sure but looks that maybe you need to setup input config option to a different value.

Maybe mplayer can help you to get that value :

mplayer tv:// -tv device=/dev/video1:input=1:normid=0
