Hello all,
I followed with great interest the discussion "Convert failure with RGB565".
It end on nov 10th, by a modification of the raw.c source file.
Unfortunatelly it seems I still encounter the same problem.
I checked out the latest version from svn and ran an conversion from
Camstudio compressed AVI to FLV, and from AVI to MPG, same problem : video
has ugly colors.

Heres is the ffmpeg output :

The AVI I used is :

Input is RGB565 and output is yuv420p
I tried changing the raw.c back to it's pre-nov 10th state, no change.
Ffplay outputs the avi file with bad colors too. I checked it on Windows
with a build made with a nov 24th extract.

Thanks for your help
