[MPlayer-users] libass/fontconfig not using fonts

[Daniel Frey]

I have a strange problem with mplayer currently. It's been doing this
for a while, but I have not found any pattern or solution for the
behaviour. Some mkvs play fine yet others do not use the right fonts.
I've checked with mkvinfo and the file attachments are there. I've even
installed the fonts to /usr/share/fonts and rebuilt the global font
cache and it still doesn't work.

I've turned on verbose logging and it simply is not using any font
available to it. They're in multiple places. No matter what I do, it
refuses to use the same font. Yet on some files with the same style
definitions it works.

Is it possible that there's some sort of filename check going on that's
failing? There's no indication of this in logs and no sort of other
commandline switches to show that type of output.

Using media-libs/fontconfig-2.6.0-r2. I've tried fontconfig 2.8.0 with
no difference.
