[gst-devel] v4lsrc and bttv with three inputs

I got it to display something by commenting out the second input check:

//  if (input) {
//    output = pipeline = input;
//  } else 
    if (fallback_v4l == FALSE) {
      input = gst_element_factory_make ("v4lsrc", "video-in");
    } else {
      input = gst_element_factory_make ("videotestsrc", "video-in");
    gst ...

It no longer core dumps and now it displays the tuner output, but when
i try to change it to the composite in, it stops displaying.

This is using two different bttv based capture boards.  Both work fine
with xawtv, so i'm pretty sure its not hardware.

Thank you for your generous help!
