- Pending track should only be triggered by stream_changed if there is one.
- Tracklist changed was incorrectly calling stop breaking tests and gapless
- Tests have been updated to capture and replay audio events. This should avoid
test deadlocks while still using the audio fakes.
- Adds stream changed handler to core
- Moves playback started trigger to stream changed
- Made about to finish store next track in _pending_tl_track
- Set the pending track as current in stream changed
- Adds tests for all of this and fixes existing tests
There is still quite a bit to be done is this area:
- We need to start tracking pending tracks as there is time window when we are
decoding a new track but still playing the old one
- Currently this breaks seek, next, prev during this time window
- The old on_end_of_track code needs to die.
- Stream changes need to trigger playing events and switch the pending track to
current.
Only handles the playing case, unlike the previous and next changes. It should
also be noted that this is just a temporary state on the road to making this
method handle gapless.
While trying to remove traces of stop calls in core to get gapless working I
found we had no way to switch to switch tracks without triggering a play. This
change fixes this by changing the backends playback provider API.
- play() now _only_ starts playback and does not take any arguments.
- prepare_change() has been added, this could have been avoided with a kwarg to
change_track(track), but that would break more backends.
- core has been updated to call prepare_change+change_track+play as needed.
- tests have been updated to handle this change.
Longer term I hope to completely rework the playback API in backends, as 99% of
our backends only use change_track(track) to translate URIs. So we should make
simple case simple, and handle mopidy-spotify / appsrc in some other way.
Run with show source so we can see the context in travis errors. Add stats for
number of errors. And limit ourselves to mopidy and tests as I happen to have
a tmp folder with non-conforming proof of concept code that I don't want this
to check.
