1. check_classic_mac_basic.yml — update to latest macOS-latest
2. docker-on-push-tag-or-pr — dependant updates
3. FFTConvolver — fix a compilation warning when the DEBUG flag is turned off
4. Reorganise some source files — e.g. move most of the metadata stuff into a subdirectory
5. Remove unused special-purpose AirPlay 2 RC event handler.
6. Reorganise source files and source code relating to the standard event handler.
7. Check configuration settings a little more carefully to offer more meaningful diagnostics.
8. Add password to AirPlay 2 and reorganise initialisation to set AirPlay 2 flags accordingly. Also, remove redundant airplay_pin.
9. Remove redundant debug facility definitions from common.h
10. Make it possible to omit all the dacp stuff from a build.
11. Make it possible to omit metadata multicast from a build.
12. Add AP2-native metadata by setting bit 50 of features to true.
13. Improve stability when pre-empting an existing play session.
14. Fix a few compiler warnings in the pair_ap library.
15. Ensure that the audio format is known before starting synchronisation.
16. Improve handle_configure to set/clear a new config setting. Doesn’t seem to do anything…
17. Experimentally turn off bit 46 of AirPlay 2 features — seems to stop failing pair-verify attempts.
2. Clean up get_audio_buffer_size_and_occupancy() and replace it with get_audio_buffer_occupancy().
3. Add a new general setting: audio_decoded_buffer_desired_length_in_seconds for managing the size of the player buffer queue when the source is buffered audio. Default is 0.75 seconds so that we can step back up to that time if older buffers appear.
(1) to be multithreaded,
(2) to work on multichannel audio and
(3) to work on 48k and 44.1k audio.
Allow multiple impulse response (IR) files with a new setting: "convolution_ir_files"
When convolution starts, Shairport Sync will look for an IR file with a sample rate
matching the input (44.1k or 48k) and channel count.
If one can't be found, it will look for a single-channel IR file with the same rate.
It will always choose the first match in the file list supplied "convolution_ir_files".
Allow multithreading -- use the "convolution_thread_pool_size" to set the number of threads to use.
Deprecate "convolution" -- use "convolution_enabled" instead.
Deprecate "convolution_max_length" -- use "convolution_max_length_in_seconds" instead.
Deprecate "convolution_ir_file" -- use "convolution_ir_files" instead.
Update corresponding D-Bus methods and properties.
Update the loudness code to work on 48k and well as 44.1k audio and with multichannel audio.
Deprecate "loudness" -- use "loudness_enabled" instead.
Update corresponding D-Bus methods and properties.
Fix a deprecated FFmpeg warning.
Update HiFi-LoFi FFT convolver to latest available.
- 48,000 frames per second operation,
- 48k lossless stereo, 5.1 and 7.1 surround sound
- Multichannel and multi rate operation on ALSA, PipeWire, PulseAudio, FreeBSD, stdout and unix pipe output backends.
Automatic, flexible and controllable output format (rate, sample format and channel count) selection.
Full FFmpeg integration to support transcoding, resampling, and new audio formats.
Better operation on lower powered devices down to e.g. Raspberry Pi B.
Reduced Docker image sizes with a slimmed-down FFmpeg library.
Enhanced timestamp handling for better synchronization.
Improved the sync error calculation.
A new "vernier" resampling and interpolation method for low-power CPUs.
Bug fixes and minor enhancements.
Note -- there are many breaking changes from previous versions of Shairport Sync!
In that situation currenctly, when you play something, it will come out at the last volume set on the device, which will be that very high volume.
This could happen, for example, the morning after a loud party :).
The new code works as follows: If nothing has been played for a period, say a few hours, and the volume is higher than a threshold, new connections that ask
for the current volume setting will be offered the default (low) volume rather than the current (very high) one.
Most players, including the HomePod mini, iOS and iPadOS use this to set their initial volume.
The Mac Music app retains its own setting, and the Mac System Sounds preference sometimes seems to take its setting from the Music app,
but at least you can see the settings they will apply.
Existing connections are unaffected, so this facility should be unobtrusive.
Add three parameters to the backend play() function call -- (1) a flag indicating whether the samples are timed or not. If timed, (2) the timestamp and (3) the local time at which the first frame should be heard.
Update missing pipewire library message.
Makefile.am fix.
Update the SHM version and fix the SHM name so that it works with FreeBSD.
Remove redundant (?) AC_HEADER_STDC check.
Fix compilation and installation under FreeBSD -- changes to allow building in a separate directory broke the FreeBSD build process.
Add AC_CHECK_LIB for gcrypt in case PKG_CHECK_MODULES fails to find it.
Find gcrypt using pkg-config
Add code to detect when the RTSP channel goes idle for a period, and use it to reset clocks and timings, etc. so that SPS resumes correctly where the source has gone to sleep while playing a realtime stream and has subsequently woken up.
Don't exit if a UDP Clock Control packet is empty. Also check minimum packet size.
Remove some very experimental code which may cause memory and port leaks.
Strip file path from the filename used in debug messages, information messages, warnings and fatal error messages.
BB fix to Makefile.am -- overwriting the DBUS stuff with MPRIS definitions, duh.
Fix some problems building on FreeBSD and tidy up the use of the "sed" editor.
Fix some problems building on picore.
Fix an uninitialised variable
start using the "nqptp" SMI
