Package: libass5
Version: 0.13.6-1
Severity: important

Dear Maintainer,

While using libass5 in combination with various media players I encountered a
bug which rendered mpv and totem completely useless and disabled most subtitles
in vlc:
"ffmpeg: symbol lookup error: /usr/lib/x86_64-linux-gnu/libass.so.5: undefined
symbol: FT_Outline_EmboldenXY"
&
"Codec not supported:
VLC could not decode the format "ssa " (SubStation Alpha subtitles)"

However, I could fix it by simply updating the package manually with a
checkinstall package from the git https://github.com/libass/libass/ and linking
the libraries manually to the newer versions so ffmpeg could find them:
"sudo ln -s /usr/local/lib/libass.so.9 /usr/lib/x86_64-linux-gnu/libass.so.5
sudo ln -s /usr/local/lib/libass.so.9.0.0 /usr/lib/x86_64-linux-
gnu/libass.so.5.3.2"

So please consider updating the package to the latest version, because
according to this thread http://forums.debian.net/viewtopic.php?f=10&t=131764
I'm not the only one with the package. I describe my solution there at the end
too.

Cheers!

Given that you have freetype-infinality installed, I don't need that
information since I already know what the problem is. To use libass from
Stretch you need freetype 2.4.10 and I'm guessing you don't have that
version. I don't know much about infinality but you may have to find
some newer patches and upgrade freetype yourself.

Since this isn't a bug in any Debian packages - I'm closing the bug.

Thanks,
James
