    em28xx-based usb capture device displaying green

    Hello, I have a em28xx-based USB video capture device, of a source I'm not sure of. The casing says "V-Stream", and has the part code VS-USB2800D. It seems to work, as the em28xx module is automatically probed, and a device mapping is made at /dev/video0. However, when I use mplayer tv:// it displays only a green screen with some corrupted colors at the top, and simply hardlocks VLC (in one case not even kill -9 was killing it)...

    I compiled and installed the v4l-dvb modules from source and nothing was solved.

    Any ideas? :\

    Isn't tv:// for analog TV? I think dvb:// is for digital. In my area there is no longer over-the-air analog TV.

    This device has no tuner, and has two inputs: a composite and S-Video. I set input=1 to get the Composite video but nothing different happens. I'll try dvb:// and edit this with the results.

    EDIT: dvb reports it is not configured.

    Re: em28xx-based usb capture device displaying green

    i've been able to make it working removing the em28xx module and giving the card=8 option:


    rmmod em28xx
    modprobe em28xx card=8

    If a post is older than a year or so and hasn't had a new reply in that time, instead of replying to it, create a new thread. In the software world, a lot can change in a very short time, and doing things this way makes it more likely that you will find the best information. You may link to the original discussion in the new thread if you think it may be helpful.
