[vlc-devel] Output level clamping filter

My vlc output is mixed with another video source by an
external chroma-key device. If the file played back
by vlc has [near] black in it then it gets mixed when
I don't want it to be!
What I want to do is something like "if (y < 10) y = 10".
I don't want to change the brightness / contrast on the
whole picture (so "Image Properties" doesn't work for me).
I can write a vout filter to do this, but just wondered
if anyone knows of an existing way to do this? I can't
find anything in the documentation or -H.
