Well I remmeber one thing - I've tried about Sun long time ago -
this system was quite old - and it has some serious problems with
C++ usage - it was not calling constructors for default objects.
I've tried later to removed them and replace them with some
basic types and delayed initilization - most probably I've not
replaced them all (and I'm not even sure if it actually possible
because this would most probably brake compatibility of the API
(which is now >2 years old and still the same ;) - sure there
are some enhancements but it should be still compliable even with
older code)

Hmm if you could give me an access to decently fast and fresh Solaris
system I may try to play with this a bit once again - otherwice
I affraid I couldn't help you much here...

ffmpeg is a part of avifile (though it's compilation for Solaris
isn't tested at all in avifile build process)

There could be a problem that codecs do not get initializaed because
of some problems with dllopening them - hard to say...

Hmm looks like some constructor has been still left somewhere
and I would have to check which one...
(try to past startup message)

you want to use uncompressed video - which is 0 (15 or 24) bit
and the bit specification is given via BITMAPINFOHEADER
(there are methods to set BitmapInfo to 15bit or 24bit surface)
You might as well use YV12 I420 UYVY - as fcc and BitmapInfo)
