Mike Brady 16b6534ad3 further changes to remove compilation warnings on 32-bit builds 2025-12-31 19:02:16 +00:00
Mike Brady 3aa34cd712 fix lots of errors calling debug() with incorrect argument patterns. 2025-12-30 14:59:27 +00:00
Mike Brady e12a3ed7b2 Do a long-overdue rebuild of the buffered audio processor and, with everything we have figured out, implement a cleaner method to handle both immediate and deferred flush requests. Remove lots of old flags and redundant code. Leave in a few debug messages. 2025-11-16 16:58:34 +00:00
Mike Brady e05448aecc Check for configuration strings that are given but turn out to be empty, issue a warning and ignore them. 2025-04-14 10:40:26 +01:00
Mike Brady 60143518c2 This squashed commit comprises a long series of improvements, bug fixes, optimizations, and new feature additions: 
- 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!

Mike Brady 2bc62c7dd9 Close the DAC when the keep_dac_busy flag is changed (by the activity monitor) from true to false. Wait a little longer for the DAC to drop all frames. 2022-09-30 10:18:51 +01:00
Mike Brady fd880056fb Squashed commit of the following: 
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
