Hello,
after the introduction of vd_black (r35249), some live streams from
rai.tv stopped working. Here is a sample to reproduce the problem:

vd_black gets selected by default, resulting in only the audio, and
not the video, being played. Of course with:

the video works. Would it be possible to change the priority/select
the old behaviour where these kind of streams worked without
additional options in the command line? (this is also important
because it broke raismth, a firefox plugin to watch rai live
streams/archives using MPlayer)
Thanks.
