this should be solved ASAP.
i suggested an option like codec_priority about a month ago.
it should override order of codecs in codecs.conf. codecs not listed with
this option remain after this list in their original order.

so, users could override codecs selection a bit more user friendly way than
vfm=5 and such hacks.

the second, and not so easy problem is libao/vo - a/v codecs connection.
as you know, they aren't all compatible. especially the hardware decoders.

we should introduce very basic automatical colorspace conversion stuff,
afaik most of needed converters are implemenetd by Michael.
so, if libvo-codec pairing fails (now user get incompatibility error) we
should choose (at least try) the best converter and use it.

of course this will be much better in libvo2, but as a quick hack, it could
help a lot. at least in delaying release...
