[MPlayer-dev-eng] [PATCH] Fontconfig -font support for font_face selection / libass -font Fontconfig patterns

[Adrian Stutz]

ping.

Any news on this patch? It's been a month now.

Also, this doesn't work together with libass. ASS treats -font as font name
by passing it as FC_FAMILY to Fontconfig, making font selection with
Fontconfig patterns unreliable. The above patch only fixes style selection
for the OSD font and subtitles not rendered by libass.

I've taken a look at libass to see if there could be an easy way around and
came up with the attached patch. It first tries to parse the family string
as a pattern before creating an empty one, as it does currently. I don't
know if that's a good idea since that means libass will try to parse any
font name as a Fontconfig pattern, even the font names from ass subtitles. I
tested both selecting a subtitle font style with -font and playing movies
with ass subtitles and both worked as expected, though.

Greetings
Adrian
