|
* Add a resampler to WASAPI outputChris Robinson2022-11-121-10/+75
| | | | | | | This allows mixing at various samples rates that WASAPI doesn't otherwise support. This is mostly helpful for users that have unnecessarily high device rates (96 or 192khz), and lets the ALC_FREQUENCY attribute or frequency config option set a lower mixing rate for more efficient processing.

|
* Add preliminary support for 7.1.4 output modesChris Robinson2022-11-0310-4/+88
| | | | | | | | I don't know how different sound APIs handle 7.1.4 ("Atmos" or "Auro3D") output, but currently it simply specifies the additional channels with the height channel labels. This isn't likely how it works for a virtualized channel bed, for playing over other with-height configurations (7.1.2, 5.1.4, etc), but this should be an okay start.

* Use an intermediate buffer for writing to the ringbufferChris Robinson2022-08-181-26/+11
| | | | | It doesn't seem as though AudioUnitRender likes being given two buffers to render/capture samples into segmented memory.

* Fix the PipeWire version checkChris Robinson2022-06-241-1/+2
| | | | | | PW_CHECK_VERSION checks if the header version is equal to or newer than the values specified, it can't be used to check if the library version is equal to or newer than the header version.
* Match exactly 5.1 Rear in WASAPIChris Robinson2022-06-161-2/+2
| | | | | So 7.1 and other configurations like it aren't detected as 5.1 Rear despite having side channels.
* Handle a blank channel mask from WASAPIChris Robinson2022-06-141-10/+18
| | | | | | | Without a channel mask, the channels are treated as "raw" or unknown. Auto- detection will only go up to stereo (assuming the first two channels are front- left and front-right), while explicit requests will work as long as there are enough channels (the user is responsible for ensuring a correct setup).

* Fix requeueing logic for OpenSLCapture::captureSamplesChris Robinson2022-05-281-17/+29
| | | | | | | | | | | | | | The write vector represents the chunks queued for OpenSL, and the write pointer only increments when OpenSL fills in more samples. So requeueing from the start of the write vector is requeueing chunks that are already queued, which is obviously wrong. It instead needs to queue chunks that become available as they're read. Because the ring buffer holds more elements than can be written to at a givem time, the read vector does not represent the next writable chunks to queue. Advancing the read pointer increases the number of writable elements, so instead of queueing from the read vector or the start of the write vector, queue from the end of the write vector given the number of chunks read.

* Reject older versions of PipeWire than built againstChris Robinson2022-05-071-0/+24
| | | | | | | | | | | | | | | | | | | Newer versions of PipeWire may add things to public structures. For example, pw_buffer::requested added in 0.3.49. Building against 0.3.49 or newer, but then running with 0.3.48 could result in invalid accesses since the returned pw_buffer objects are shorter than the definition says to expect, creating undefined behavior. Even if explicit access to the additional fields is protected by a runtime check, the language allows the compiler to assume a pointer to a pw_buffer object contains a complete pw_buffer, allowing the optimizer to access the field earlier than the check (with the check only controlling if the value gets used). Another example is pw_time, which had a few fields added in 0.3.50 along with a function, pw_stream_get_time_n, that provides the size of the pw_time struct the application is using (so the library knows what version of the struct it has to fill in). If a later version adds a new field, running it with an older version will either fail (due to the library getting a size larger than it knows about) or silently leave the newer fields as garbage.
* Avoid a deprecated PipeWire functionChris Robinson2022-05-061-4/+17
| | | | | Building against 0.3.50 or newer will require that version or newer at runtime. Building against a version before 0.3.50 will work with newer versions.
* Fix CoreAudio audio unit element values for captureChris Robinson2022-05-021-19/+21
