[FFmpeg-devel] [PATCH] swscale: add generic yuv2yuv wrapper function

[Ramiro Polla]

This is a patch series that cleans the yuv2yuv functions inside
rgb2rgb.c a bit (and removes their global function pointers).

Now I'm stuck in a bikeshed issue. There is one rgb2yuv function in
there (rgb24toyv12). So "yuv2yuv_func" and "Yuv2YuvFunc" don't sound
too great anymore. How should it be named?

I also plan on having another function pointer in the context to
simplify rgb2rgb (they'll take another set of parameters though). I'm
thinking of adding a "void *priv_data" to the context so that at some
point later on it will be possible to split the fields in the context
and only allocate/initialize them depending on the scaler chosen.
Would this be a good place to put the function pointers?
