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 3cbf773995 Add a new command line option "--displayConfig" to give version string, command line and active configuration file name and settings. 
Clean up and reorganise the help messages and fix a few mistakes.

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

Mike Brady 14bfba2724 Add code to check divisions and mods for a potrntial divide by zero problem. MAy cause SPS to terminate but leave a log message. 2021-11-21 21:47:32 +00:00
Mike Brady cd9da86fc3 Add a 'stats' function to the audio back ends to replace the 'rate_info' function. Zero all except the alsa back end. 2021-11-20 13:59:16 +00:00
Mike Brady 54d761ff7d Clean up some of the wording and layout of the configuration file 
Clean up and improve the way lead-in sillence is used to give a more accurate sync time to the first packet of audio.
Allow very good sync to occur with 0.3 seconds of lead-in silence.
Improve the use of the buffer offset.
Format some other files.

Mike Brady 4c6b0e83c5 Remove some unwanted and unused variable declarations from audio_dummy.c and audio_soundio.c 2020-02-18 16:25:28 +00:00

Mike Brady 83c0405d03 Add automatic bit depth and speed selection for alsa devices. Set rate and format to "auto" by default. Always look for the greatest bit depth, but the lowest multiple of 44,100. 
Improve support for big-endian CPUs by adding support for explicit -endian formats, i.e. S16_LE, S16_BE, S24_LE, S24_BE, S32_LE, S32_BE.

For the "disable_standby_mode" setting, change "while_active" to "auto".

Mike Brady aa5698fce2 Remove the preflight call - don't seem to need it. 2019-01-27 15:53:36 +00:00
Mike Brady 2e4428538d Add an "active" mode that can time out after a period -- 10 seconds by default -- after play ends. 2019-01-21 21:43:55 +00:00
Mike Brady caf06c5aba Add the idea of a preflight message to tell the backend that frames will be coming... 2019-01-07 17:34:50 +00:00
Mike Brady 8cabb16f25 Initial very rough attempt at a jackaudio backend. 2018-08-31 12:39:18 +01:00
Mike Brady 76c5dd9285 Stop using SIGUSR1 for cancelling threads, use pthread_cancel and friends instead, fix some memory leaks, add accurate ouput rate calculation to statistics, add "quit" verb to MPRIS and native d-bus interfaces. Probably still buggy. 2018-07-30 10:07:11 +01:00
Mike Brady ea20840d6c Make the play function return a status (ignored for the present). Clean up audio_alsa by removing all the die calls and placing the alsa_mutex calls in pthread cleanup routines. 2018-07-29 13:45:42 +01:00
Mike Brady f1d4503431 Try to add proper cancellation code to all threads -- not complete, buggy. 2018-07-20 13:50:38 +01:00
Mike Brady 3fbd47ad05 Fix minor warnings from some of the backend modules and make the configure messages a little more helpful. 2018-05-18 15:22:20 +01:00

Mike Brady b7864b4ecf Move common audio backend settings like buffer size and offsets to the "general" settings stanza. Improve the resync code a little. 2017-07-21 12:29:03 +02:00
