Original commit message from CVS: This patch fixes some issues caused by design issues in video4linux, adds some nicety to video4linux2 plugins and does some more evil stuff: * video4linux doesn't tell us which formats are supported by a card, so the only way to know this is by simply trying it out. This patch adds that. * v4lmjpegsink didnt have a bufferpool yet - is integrated now. * all copy() bufferpool functions have been removed since they're not needed. * v4lmjpegsink doesnt have a free() function, because hen playing the frames, all this is already handled. When the frame is not played, nothing has to be done. In total, the function is not needed. * adds a get_caps() function to v4l2src * some minor crap
