On a machine here, they cause the following error:
raise MPVCommandError("%r: %s" % (message["command"], e))
aqt.mpv.MPVCommandError: ['keybind', 'q', 'stop']: invalid parameter
The problem was caused by stop() doing a spin loop on the main
thread waiting for the completion signal. This prevented Qt's run
loop from executing, and so the completion signal was never delivered,
meaning longer files would time out.
Fixed by reworking the code so that stop() does not block at all -
instead it just sets the termination flag, and AVPlayer does not
unset current_player. Then when the completion callback fires, it
can advance to the next file.
TTS code still needs updating, and the lock should be safe to remove
as the start/stop logic is all on the main thread.

the lock should at least ensure _process doesn't disappear in the
middle of our logic, and the longer wait should reduce the chances
of .stop() timing out and allowing multiple audio files to play
Not very happy with the current approach, as in the timeout case
you have multiple threads competing to access the same data
We can now show replay buttons for the audio contained in {{FrontSide}}
without having to play it again when the answer is shown.
The template code now always defers FrontSide rendering, as it wasn't
a big saving, and meant the logic had to be implemented twice.
- use provided language and voices when playing on Mac
- fix hang in waiting for termination
- allow players to return a rank for a given tag,
which will allow for the best matching player to be chosen
depending on the context (eg, prioritize one player for videos,
one tts player for certain voices, etc)
This solves a few problems:
- We no longer need to write temporary files to disk, as files
passed on the command line with non-Latin text can be read by mplayer.
- We no longer need to deal with mplayer processes left around in
the background that have failed to terminate.
- We don't need to deal with the added complexity that comes with
polling mplayer's status output to determine when the file has finished
playing.
Also add seek_relative(), toggle_pause() and shutdown() as optional
methods on AVPlayer.
