  Playback: Fix text subtitles with FFmpeg 5.1

FFmpeg 5.1 enforces a new way of handling ass subtitles. This has been
in the FFmpage code since 2016, but now the old method is deprecated and
removed from the FFmpeg code. See https://github.com/FFmpeg/FFmpeg/commit/2941282

This commit Changes MythTV to use the libass API that handles the new format.

Fixes #676
