[FFmpeg-devel] [SWScale]Creating my own filter

[Jean-Michel Hautbois]

Hi all !

I would like to create my own upscaling filter, inspired by the fast
bilinear filter, inside the libswscale.
But I have to say it is quite complex... I can't find any docs (and
some messages on this mainling list say there is not :)), and there
are a lot of macros defining functions.
So, I don't really know where to start. The main objective is to make
an ARM optimized scaler, but in order to do that, I would like, as a
start, to re-create a bilinear one.

Thanks for any help you can give me !

Regards,
JM
