[GEM-dev] Gem says quicktime ok, then disagrees with itself

Hey again,

Well after a LOT more digging I found some things out. First off I
realised that mplayer was decoding my DV MOV with ffmpeg. Good news, so
I messed with ffplay some more and finally got it to load my MOV the
same as totem & mplayer (using ffmpeg).

So the issue seems to be that ffmpeg does not know what kind of file it
is, but knows how to decode it.

ffplay dv.mov

gives:

unkown format

ffplay -f dv dv.mov

Works!!!

So we need to force ffmpeg to try a certain codec in this case... Is
this possible from inside Gem? Clearly ffmpeg is much better at decoding
than recognizing formats, could there be a manual mode to specify the
codec manually to pix_film ? Or is there some other library (code from
mplayer?) that actually IS good at recognizing formats? mplayer actually
tries to load the DV file with qdv.dll but since it is not on my system
it gives up and tries ffmpeg, and clearly tells it what format to expect.

So I feel much closer to loading this file in Gem, what do I need to do
to get it to actually work? (now that it is clear that ffmpeg will play
it).

Thanks.
