Yes. It is not included ebcause it doesn't work. Once I tried to
upgrade the DLL loader from avifile, but it broke Indeo codecs...
Btw aviplay had problems with Morgan's mjpg codec as well.

It's true for the fsdga driver, but the basic 'dga' must work with AVI.

Btw it works well only in 24/32 bpp. 15/16 bpp has prblems...
Maybe you tried a 15bpp AVI in 16bpp... (the dga driver can't convert
15<->16 bpp yet)

oh... it's that. try 32bpp...

It works only with 24/32bpp, as mentioned in teh docs, and mpeg-only.
it's too slow yet, because it's pure C. MMX experts are still wanted!!!

You should email these to Eugene (avifile author, divx at euro.ru), he
is the only man who understand that linux DLL loader :)
[I'm just using that part of avifile.]

try to set           avi_header.flipped=1;
in codecs.c, it disables flipping by codec.

it means that codec calls an unimplemented win32 API function 'GetWindowDC'
(btw I don't know why the codec requires access to WindowDC...)
