It turns out that “seeking to a first sample in a not–first block” is actually very common, because Tangara only seeks to exact seconds and the reference encoder tends to size blocks in a way that makes the first sample in a block likely be the sample that the firmware wants to seek to.
|
|
This allows you to use the touch wheel for quick playback control:
- bottom quadrant for play/pause
- left and right quadrant for track skip back / forward
- top quadrant to seek back 25 seconds (handy when listening
to a podcast)

This increases CPU usage by ~2% for the audio_conv task, which I
think is an acceptable tradeoff. The Speex resampler still
makes its own allocations in internal RAM.

The decoder does use `memset` on the buffer, but according to Espressif that should be fine.

This is from an upstream development branch at [1] and adds quite a lot
of glyps for the 12px font, and a few to the 10px font.
This addition should be temporary until that feature branch is merged
upstream, a new release rolled, and then a new release of the fuxion
pixel font is rolled. For now this leads to no more missing extended
latin A/B characters in the 12px font on my collection.

The SetTrack event is sent when *decoding* finishes, not when
*playback* finishes so the decoder can start buffering the next
track in advance of its playback to ensure gapless playback.
Clearing StreamCues causes
Playback::react(const internal::StreamHeartbeat& ev)
to transit the Playback FSM to Standby, which sets the
IAudioOutput to stop reading from the output buffer. Thus,
clearing StreamCues in response to the SetTrack event paused
playback with the end of the track stuck waiting in the output
buffer. When a new queue was loaded and started playing, the
end of the previous track would be played before the new track
was played.

This drops CPU usage for the audio_dec task by about 15%.
|
|
This is the maximum amount that malloc can currently allocate in a
single allocation.
|
|
This adds support for Latin Extended-A, Latin Extended-B, and Greek
and Coptic scripts. The used fusion font in the current version
support for these is clearly incomplete for the first two, there is
however an upstream branch of the ark pixel font that is a base for it
to add more support for those.
In the current state this reduces the amount of missing characters for
a whole set of Eastern and South-Eastern European languages.

Splits the control scheme into separate schemes for the side buttons and touchwheel, allowing them to be configured independently of each other. At least one input must be used for navigation, and there are guards to prevent locking oneself out of any input. If the input scheme is invalid, a pop up will show alerting the user.
Different behaviours can be bound to the side buttons for when the device is locked or unlocked. This PR also adds a mode for these buttons that controls media playback (prev/next on up/down, pressing both buttons toggles play/pause).
There are some changes to the way inputs handle locking. Rather than the input devices tracking the current locked mode, different input devices are created on lock depending on the mode that is configured.

Prior to this change, the UI thread was consuming approx. 10-14% CPU
in the idle state, and appeared to be running in an endless loop.
After this change, the UI thread is measured at about 0.1% CPU. I'm
not sure what the current consumption impact is, but it's gotta be
a power saving, even if slim?
Following manual testing with the device after flashing this change,
the UI responsiveness and music playback does not appear to be
negatively affected. The UI actions that were tested were:
- Scrolling through items on the root menu
- Scrolling through settings
- Scrolling through All Tracks with long-press on the bottom of
the scroll wheel (Page Down) on a device with ~20k songs
- Repeatedly hitting 'next track'
- Forcing a DB update, and scrolling through All Tracks while
updating the database.
The device was configured with the following settings when tested:
- TTS enabled
- Wired headphones
- Bluetooth enabled but not connected
- No DB auto-update
- Playing music
Prior to this change, the UI thread was consuming approx. 10-14% CPU
in the idle state, and appeared to be running in an endless loop.
