[FFmpeg-devel] av_parse_color() improvement

[Aurelien Jacobs]

Hi,

Attached patch makes the av_parse_color() a bit more versatile.
It allows parsing of html formated hex color (ie. starting with a #
instead of 0x), including its loose form where the # is missing.
This makes quite some sens as the function is already able to parse
html named colors.
This is required to be able easily use this function to parse colors
out of SubRip files.
