* sdlaudio: add -audiodev sdl,out.buffer-count optionVolker Rümelin2021-01-151-1/+1
| | | | | | | | | | | | | | | | | | | Currently there is a crackling noise with SDL2 audio playback. Commit bcf19777df: "audio/sdlaudio: Allow audio playback with SDL2" already mentioned the crackling noise. Add an out.buffer-count option to give users a chance to select sane settings for glitch free audio playback. The idea was taken from the coreaudio backend. The in.buffer-count option will be used with one of the next patches.

* audio: proper support for float samples in mixengKővágó, Zoltán2020-02-061-16/+25
| | | | | | | | | | | | | | | This adds proper support for float samples in mixeng by adding a new audio format for it. Limitations: only native endianness is supported. None of the virtual sound cards support float samples (it looks like most of them only support 8 and 16 bit, only hda supports 32 bit), it is only used for the audio backends (i.e. host side).

* coreaudio: fix coreaudio playbackVolker Rümelin2020-02-061-0/+7
| | | | | | | | | | | | | | | | | | | | There are reports that since commit 2ceb8240fa "coreaudio: port to the new audio backend api" audio playback with CoreAudio is broken. This patch reverts some parts the commit. Because of changes in the audio subsystem the audio clip function in v4.1.0 of coreaudio.c had to be moved to mixeng.c and the generic buffer management code needed a hint about the size of the float type. This patch is based on a patch from Zoltán Kővágó found at https://lists.nongnu.org/archive/html/qemu-devel/2020-01/msg02142.html.

* audio: api for mixeng code free backendsKővágó, Zoltán2019-09-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | This will make it possible to skip mixeng with audio playback and recording, allowing us to free ourselves from the limitations of the current mixeng (stereo, int64 samples only). In this case, HW and SW voices will be essentially the same, for every SW voice we will create a HW voice, since we can no longer mix multiple voices together. Some backends expect us to call a function when we have data ready write()/read() style, while others provide a buffer and expects us to directly write/read it, so for optimal performance audio_pcm_ops provide methods for both cases. Previously backends asked mixeng for more data in run_out/run_it, now instead mixeng or the frontends will call the backends, so that's why two sets of functions required. audio.c contains glue code between the two styles, so backends only ever have to implement one style and frontends are free to call whichever is more convenient for them.

* audio: reduce glob_audio_state usageKővágó, Zoltán2019-08-211-24/+22Star
| | | | | | | | | | | | | | | | | Remove glob_audio_state from functions, where possible without breaking the API. This means that most static functions in audio.c now take an AudioState pointer instead of implicitly using glob_audio_state. Also included a pointer in SWVoice*, HWVoice* structs, so that functions dealing them can know the audio state without having to pass it around separately. This is required in order to support multiple simultaneous audio backends (added in a later commit).

* audio: -audiodev command line option basic implementationKővágó, Zoltán2019-03-111-4/+38
| | | | | | | | | | | | | | | | | | | | Audio drivers now get an Audiodev * as config paramters, instead of the global audio_option structs. There is some code in audio/audio_legacy.c that converts the old environment variables to audiodev options (this way backends do not have to worry about legacy options). It also contains a replacement of -audio-help, which prints out the equivalent -audiodev based config of the currently specified environment variables. Note that backends are not updated and still rely on environment variables. Also note that (due to moving try-poll from global to backend specific option) currently ALSA and OSS will always try poll mode, regardless of environment variables or -audiodev options.

* audio: Replace AUDIO_FUNC with __func__Alistair Francis2018-02-061-13/+13
| | | | | | | | | | | | | | | | | | Apparently we don't use __MSC_VER as a compiler anymore and we always require a C99 compiler (which means we always have __func__) so we don't need a special AUDIO_FUNC macro. We can just replace AUDIO_FUNC with __func__ instead. Checkpatch failures were manually fixed.

* audio: expose drv_opaque to init_out and init_inKővágó, Zoltán2015-06-151-1/+1
| | | | | | | | | | | Currently the opaque pointer returned by audio_driver's init is only exposed to the driver's fini, but not to audio_pcm_ops. This way if someone wants to share a variable with the driver and the pcm, he must use global variables. This patch fixes it by adding a third parameter to audio_pcm_op's init_out and init_in.

* audio: Don't free hw resources until after hw backend is stoppedPeter Maydell2014-12-231-1/+1
| | | | | | | | | | | | | | When stopping an audio voice, call the audio backend's fini method before calling audio_pcm_hw_free_resources_ rather than afterwards. This allows backends which use helper threads (like pulseaudio) to terminate those threads before the conv_buf or mix_buf are freed and avoids race conditions where the helper may access a NULL pointer or freed memory.

| | | | | | | | | | | | | | | Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
