yuv<->rgb conversion in video filters

[koyaya]

Hello
I am writing a filter and i need to work in RGB domain for this so i need a yuv <-> rgb conversion
can I use filters in modules/video_chroma/ and how (references to any existing code should be enough)
or are there other ways to do it?

You cannot change the input format. Refer to the posterize filter for reference on dealing with this case.

Remi, thanks for the answer
i see references to modules/video_filter/posterize.c
but its not there in the tree any more..
i saw function in modules\video_chroma? are they relevant?

It is in the tree. You must be looking at the wrong tree.
