Selecting via colorspace wouldn't help with the particular problem Carl
was talking about (VDP decoder creation failing because another process
on the machine is using it). The colorspace would have already been
negotiated by the time MPlayer notices that it can't actually create a
decoder for that colorspace. So you'd still have the same situation
where decoder creation fails and things have to be retried starting from
an earlier point. To avoid that you'd need something like reserving
resources at query_format stage.
