FontConfig::_available_fonts to use the font ID as a key, but that's
totally wrong because the same Font object with the same ID can have
its font filename/data changed, and in that case we don't want to
use the cached font.
Here we use the actual TTF/OTF font data as the key. We could have
just hashed the data (whether it comes from a disk file or is held
in memory) but this is slower in the case where we have the filename,
as then the file must be loaded from disk for each comparison.
This fixes #2518.
Fix subtitle font handling with in-memory fonts from SMPTE (#2509).2023-04-09T15:23:20ZCarl Hetheringtoncth@carlh.net2023-04-07T23:04:37Zurn:sha1:1c73379ed8483dcf71c5ccfc459c2c22516a9aef
Previously we would fail to make a font available if it came from
a SMPTE MXF. In that case we have a memory buffer containing the
TTF/OTF file but no file; here we add a hack/workaround so that
in-memory font files can be used by FontConfig.
Ask fontconfig to scan the system for fonts requested by text subtitle files (#2264).2022-06-07T15:01:06ZCarl Hetheringtoncth@carlh.net2022-06-02T10:20:41Zurn:sha1:280a456ae1da8fa648be1e9f68140f045b306e32Move fontconfig-related code out to a class.2022-06-07T15:01:06ZCarl Hetheringtoncth@carlh.net2022-06-02T10:52:59Zurn:sha1:9a7b67aee32a40539f29bc2d7017edd4a4f65f11
