Recently laid hands on an mkv file encoded in H264/avc.. would not play.. a look at the source's forums indicated there WERE NO UNIX TOOLS to play these files yet, so i'm requesting a prompt bug fix.
thank you, a proud X.4 tiger user

That's much better, but still needs optimization/debugging for the H.264 decode (thus the non-official build).
I see a lot of progress, but i'd also like to sumbit feedback:
The symptoms I'm getting on my system:
LOTS of choppy pans (frame drops or simply decoding error?)
use of any other system resource causes the video feed to freeze (and occasionally crash)
attempts to rescale while playing cause the vid to freeze.

I've been hearing reports that FFmpeg's version of H.264 is severely lacking in optimizations which means even modern cpu's can't keep up.
-If the dev's are not alreay doing so might I suggest they attempt to pipe any H.264 streams to the quicktime 7 framework first before reverting to ffmpeg while the bugs/optimizations to the ffmpeg h264 decoder are ironed out? [or perhaps offer users a check box which will specify this action in OsX & windows versions?]
