2267	contrast loss when encoding from h264 yuvj420p to mpeg4 yuv420p	sperate		"When trying to encode from "".mov"" files from a camera to avi (mpeg4 or libxvid) the output movie colors seemed dull.
I figured out it was a catrast loss.

How to reproduce:
{{{
% ffmpeg -i input.MOV -b:v4000k output.AVI
or
% ffmeg -i input.MOV -b:v4000k -vcodec libxvid output.AVI

}}}

I get rid of the problem by trying to enhance the contrast with
{{{
-vf mp=eq=0:5
}}}
then figured out that just using the mplayer filter without modifing the contrast gave the best result
{{{
-vf mp=eq=0:0
}}}

It seems to be a color space problem fixed with this filter but there must be a better way of getting rid of this contrast loss ???"	defect	closed	normal	swscale	git-master	duplicate					0	0
