[FFmpeg-devel] [PATCH] lavc/videotoolboxenc: Add support for HEVC with Alpha.

[FFmpeg-devel] [PATCH 1/4] avcodec/xpm: Minor speed increase to function hex_char_to_number()

Search for 0 to 9 first as this is 10/16th of possible choices we want, then search for lowercase 6/16th, or uppercase 6/16th possible choices. This gives us a minor speed increase similar to xbmdec.c nibble search. Some modern compilers complain if using "unsigned" without using "int".
