The audio backend of Firefox on Mac OS X.

cubeb-coreaudio-rs

Rust implementation of Cubeb on the MacOS platform.

Current Goals

• Keep refactoring the implementation until it looks rusty! (it's translated from C at first.)
  • Check the todo list

Status

This is now the Firefox's default audio backend on Mac OS.

Install

Install cubeb-coreaudio within cubeb

Run the following command:

curl https://raw.githubusercontent.com/mozilla/cubeb-coreaudio-rs/trailblazer/build-audiounit-rust-in-cubeb.sh | sh

Other

Just clone this repo

Test

Please run sh run_tests.sh.

Some tests cannot be run in parallel. They may operate the same device at the same time, or indirectly fire some system events that are listened by some tests.

The tests that may affect others are marked #[ignore]. They will be run by cargo test ... -- --ignored ... after finishing normal tests. Most of the tests are executed in run_tests.sh. Only those tests commented with FIXME are left.

Git Hooks

You can install git hooks by running install_git_hook.sh. Then pre-push script will be run and do the cargo fmt and cargo clippy check before the commits are pushed to remote.

Run Sanitizers

Run AddressSanitizer (ASan), LeakSanitizer (LSan), MemorySanitizer (MSan), ThreadSanitizer (TSan) by sh run_sanitizers.sh.

The above command will run all the test suits in run_tests.sh by all the available sanitizers. However, it takes a long time for finshing the tests.

Device Tests

Run run_device_tests.sh.

If you'd like to run all the device tests with sanitizers, use RUSTFLAGS="-Z sanitizer=<SAN>" sh run_device_tests.sh with valid <SAN> such as address or thread.

Device Switching

The system default device will be changed during our tests. All the available devices will take turns being the system default device. However, after finishing the tests, the default device will be set to the original one. The sounds in the tests should be able to continue whatever the system default device is.

Device Plugging/Unplugging

We implement APIs simulating plugging or unplugging a device by adding or removing an aggregate device programmatically. It's used to verify our callbacks for minitoring the system devices work.

Manual Test

• Output devices switching
  • $ cargo test test_switch_output_device -- --ignored --nocapture
  • Enter s to switch output devices
  • Enter q to finish test
• Device collection change
  • cargo test test_device_collection_change -- --ignored --nocapture
  • Plug/Unplug devices to see events log.
• Manual Stream Tester
  • cargo test test_stream_tester -- --ignored --nocapture
    • c to create a stream
    • d to destroy a stream
    • s to start the created stream
    • t to stop the created stream
    • r to register a device changed callback to the created stream
    • v to set volume to the created stream
    • q to quit the test
  • It's useful to simulate the stream bahavior to reproduce the bug we found, with some modified code.

TODO

See todo list

Issues

• Atomic:
  • We need atomic type around f32 but there is no this type in the stardard Rust
  • Using atomic-rs to do this.
• kAudioDevicePropertyBufferFrameSize cannot be set when another stream using the same device with smaller buffer size is active. See here for details.

Test issues

• Fail to run tests that depend on AggregateDevice::create_blank_device with the tests that work with the device event listeners
  • The AggregateDevice::create_blank_device will add an aggregate device to the system and fire the device-change events indirectly.
• TestDeviceSwitcher cannot work when there is an alive full-duplex stream
  • An aggregate device will be created for a duplex stream when its input and output devices are different.
  • TestDeviceSwitcher will cached the available devices, upon it's created, as the candidates for default device
  • Hence the created aggregate device may be cached in TestDeviceSwitcher
  • If the aggregate device is destroyed (when the destroying the duplex stream created it) but the TestDeviceSwitcher is still working, it will set a destroyed device as the default device
  • See details in device_change.rs

Branches

• trailblazer: Main branch
• plain-translation-from-c: The code is rewritten from C code on a line-by-line basis
• ocs-disposal: The first version that replace our custom mutex by Rust Mutex

cubeb-coreaudio-rs's Issues

Integrate the test in the cubeb project

We should run the tests in the main cubeb project automatically in the travis server.

`position` keeps growing even when stream is stopped

The failing test in BMO 1654699 indicates the position keeps growing when stream is already stopped.

I guess the reason is that interpolated_frames is increased unlimitedly.

One approach is to add outframes to OutputCallbackTimingData and use it to create a bound for interpolated_frames (e.g., interpolated_frames = min(interpolated_frames, outframes)). Or we can apply the same manner on WASAPI backend for this case.

Best strategy for pre-allocating buffers used in I/O callback

Hi there,

I'm using cubeb-rs to build an audio application (for macOS only at the moment) capable of some level of audio processing. As a result, I'm writing my own audio processing graph which involves chaining a set of audio processing nodes together and run the audio input/output through them on each I/O callback. Some of the nodes require pre-allocating buffers in order to perform their tasks.

At the moment, I'm using a naive approach of pre-allocating the same amount of space as specified when creating the I/O stream (i.e. the StreamBuilder::latency() I specified when creating the Stream).

I realize there are a few possible issues with this approach:

1. It's possible that the requested buffer size can not be fulfilled by the audio device (e.g. due to the size being too small or too large)
2. It's also possible that the buffer size may work initially, but if the underlying device of the stream changes (e.g. due to the initial device being disconnected), then the new device could have a different sample rate, causing resampling happening internally in cubeb, then causes the I/O callback to use a different buffer size (for example, if the initially connected device has a sample rate of 48000 and a buffer size of 256, when it disconnects and the stream falling back to another device with sample rate of 44100, then the audio I/O will start to tick with input/output buffer size of 279, at which point the pre-allocated buffers in the audio processing nodes are no longer sufficient)

For 1), I tried to find an API for figuring out the actual buffer size (or latency) of the audio stream after it has been created. However neither Stream::latency() or Stream::input_latency() seem to return the actual buffer size.

For 2), the only way I can think of now is to write some code to stop the audio stream once a device change is detected (e.g. via the device changed callback of Stream), then re-allocate buffers if needed and try to restart the stream using the new device.

Would be keen to hear your thoughts.

Thanks.

Test failure with Blackhole installed

With this, which is very useful:

thread 'backend::tests::api::test_get_same_group_id_for_builtin_device_pairs' panicked at 'assertion failed: group_ids.insert(source, id.into_string().unwrap()).is_none()', src/backend/tests/api.rs:1268:1

Looks like it's BlackHole_ModelUID multiple times.

Have an easy way to turn on the `cubeb_log!`

The cubeb_log! won't print anything now. We should have a way to turn on those logs so it can help debugging.

Firefox crash when running cubeb-coreaudio-rs `./run_tests.sh`

STR on an M1 Max (not sure if relevant):

• Play audio in Firefox, using the Web Audio API (I was playing something on soundcloud)
• Run the tests via the wrapper script: ./run_tests.sh

Expected:

• It messes up the audio, because it changes the default audio output device a few times, etc.

Actual:

• It messes up the audio, and then Firefox crashes, here's a report: https://crash-stats.mozilla.org/report/index/ec88b375-440d-4d32-9c74-93f7b0220412. It's probably crashing on https://hg.mozilla.org/mozilla-central/file/872b574394a6e1f97ed229b6d2d9a3fa5bbac298/third_party/rust/cubeb-coreaudio/src/backend/mod.rs#l1258, more or less the same as https://bugzilla.mozilla.org/show_bug.cgi?id=1762563#c1.

I think we need to stop putting in asserts like this, it's really annoying to crash on something like that. It's a lot better to simply rely on the system erroring out and this crate or Firefox dealing with the error.

Disable automatic device switching if user doesn't follow the system default device

To unblock BMO 1735201 and BMO 1238038, CUBEB_STREAM_PREF_DISABLE_DEVICE_SWITCHING needs to be implemented in this crate.

Hit MOZ_CRASH(attempt to subtract with overflow) at mod.rs:599

When I tried enabling the rust backend by default in Firefox, I hit a crash at line 599:

let output_latency_ns = (audio_output_time - now) as u64;

I guess that might be caused by audio_output_time - now. @padenot, could you take a look?

frames_queued and total_output_latency_frames may not update in a synchronized fashion

frames_queued is in the TripleBuffer, but total_output_latency_frames is not (it's a separate atomic), so position() might be using two values from different invocations to the audio output callback. This is probably not a big problem in practice, because total_output_latency_frames probably does not vary very much if the audio callback is called at consistent times. But it's probably still worth fixing, by moving total_output_latency_frames into the TripleBuffer.

I temporarily allow this for now since I cannot find serious bugs related to this. But it's better to take care of the threading issue more carefully.

Investigate why `activate_clock_drift_compensation` has less than 2 sub devices

In BMO 1677766, we've seen AggregateDevice::activate_clock_drift_compensation could have less than 2 subdevices:
https://github.com/ChunMinChang/cubeb-coreaudio-rs/blob/87667052a5ffaf47fbeac4ae67f1ecdefa8d7b09/src/backend/aggregate_device.rs#L485-L488
after AggregateDevice::set_sub_devices_sync is set successfully.
https://github.com/ChunMinChang/cubeb-coreaudio-rs/blob/87667052a5ffaf47fbeac4ae67f1ecdefa8d7b09/src/backend/aggregate_device.rs#L45-L47

One possible reason I could think now is that kAudioAggregateDevicePropertyFullSubDeviceList, which is used in AggregateDevice::set_sub_devices_sync,
https://github.com/ChunMinChang/cubeb-coreaudio-rs/blob/87667052a5ffaf47fbeac4ae67f1ecdefa8d7b09/src/backend/aggregate_device.rs#L273-L277
is not synchronous or symmetric to kAudioObjectPropertyOwnedObjects,
which is used in AggregateDevice::activate_clock_drift_compensation
https://github.com/ChunMinChang/cubeb-coreaudio-rs/blob/87667052a5ffaf47fbeac4ae67f1ecdefa8d7b09/src/backend/aggregate_device.rs#L462-L466

To get rid of the crashes caused by this assertion in Firefox, #118 change the code and return an error instead. However, it's better to investigate how to set the aggregate properly to avoid getting logical conflicts in our code. Ideally, once we confirm that we've set at least one input and at least one output device into the sub-device list, "number of sub-devices > 2" should be the invariant in the following calls.

Replace `assert!` by `debug_assert!` for release build

Replacing assert! by debug_assert! for release build can prevent panic! from being called and cause a crash. We should figure out what assert! should be replaced.

Do not reinitialize audio stream if its device isn't changed

Step to reproduce

0. Make sure the computer has at least two input/output devices, and device S is the system default input/output device
1. Initialize an input/output stream with device X, where X is not the system default input device.
2. Change the system default input/output device to another device

Expect

The audio stream keeps playing without being initialized.

Actual

The audio stream is re-initialized even though nothing change for its device

Fix the clippy warnings

We have lots of clippy warnings that need to be fixed. We should add the clippy check in the .travis.yml as what we do in audio-mixer.

Force builtin devices to have same group_id

To better support BMO 1624322, we need to make sure the builtin devices (or AirPods) returns the same group_id.

`audiounit_get_{current,preferred}_channel_layout` behaves differently on recent MacBook Pro

On a mid-2018 MacBook Pro (MacBookPro15,1 running 10.14) using the default speakers, test_get_current_channel_layout_output and test_get_preferred_channel_layout_output fail with:

thread 'backend::tests::api::test_get_current_channel_layout_output' panicked at 'assertion failed: `(left == right)`
  left: `[Silence, Silence]`,
 right: `[FrontLeft, FrontRight]`', src/backend/tests/api.rs:782:9

For whatever reason, the AudioChannelLayout queried via AudioUnitGetProperty(kAudioUnitProperty_AudioChannelLayout) appears to be valid/correctly initialized (52 bytes) but is mostly filled with zero values:

AudioChannelLayout.mChannelLayoutTag == kAudioChannelLayoutTag_UseChannelDescriptions (0),
AudioChannelLayout.mChannelBitmap == 0,
AudioChannelLayout.mNumberChannelDescriptions == 2,
{
  AudioChannelDescription.mChannelLabel == 0,
  AudioChannelDescription.mChannelFlags == 0,
  AudioChannelDescription.mCoordinates == [0.0, 0.0, 0.0],
},
{
  AudioChannelDescription.mChannelLabel == 0,
  AudioChannelDescription.mChannelFlags == 0,
  AudioChannelDescription.mCoordinates == [0.0, 0.0, 0.0],
}

...which results in audiounit_convert_channel_layout returning a Vec of [mixer::Channel::Silence, mixer::Channel::Silence], causing the tests expecting [mixer::Channel::FrontLeft, mixer::Channel::FrontRight] to fail.

It's not clear to me the correct way to handle this situation. Whether it's correct or not, I noticed that other code querying kAudioUnitProperty_AudioChannelLayout often treats AudioChannelLayout.mNumberChannelDescriptions <= 2 as special and forces mono/stereo examining the AudioChannelDescriptions only for the > 2 case.

FWIW, kAudioUnitProperty_SupportedChannelLayoutTags in the same context returns kAudioUnitErr_InvalidProperty.

Chun-Min mentioned that @padenot has seen the same issue on a 2019 MBP.

Correct the stream identifier in `stream_init`

Travis CI free usage ends Dec 3; mozilla repos should switch to other CI platforms

Same issue as mozilla/cubeb-pulse-rs#64

We should probably move from Travis CI to CircleCI

Update `coreaudio-sys` to work with beta

Fix comment in #57

Initialize a duplex stream properly when using aggregate device

A problem is found when investigating BMO 1631814.

The properties of a duplex stream are initialized with different devices when we use an internal aggregate device. The AudioUnit with out_dev_info but current_latency_frames and output_source_listener will be set via output_device. The output_device and out_dev_info are different values when we use an internal aggregate device for the duplex stream.

Run sanitizer tests on circle-ci

#124 will initialize the settings for circle-ci but it only runs the regular tests. We should turn on the sanitizer tests as well, which requires to be run with Rust nightly

The reason is smiliar to servo/servo#19756

Boost the speed when opening multiple streams simultaneously

In the current C implementation, each time when the stream starts, we will first try locking the mutex within cubeb context to avoid racing with reinit/destroy/stop, then call stream-start.

In the current Rust implementation, each time when the stream starts, we will dispatch this operation to the same task queue where reinit/destroy/stop is on to avoid racing issues.

Starting a cubeb stream in both implementations above requires sharing a resource in its cubeb context to avoid racing issues. For this reason, when opening multiple streams (in same cubeb context) at the same time, the stream-start will be executed sequentially, while they could actually be run in parallel since they are not sharing data.

To boost the speed when opening multiple streams at the same time, we could

1. either move the task queue for stream operations, serial_queue, from cubeb context to cubeb stream
   • This might relate to the refactoring plan: separate the audio stream into inner and outer
2. or use a dummy mutex, Mutex<()>, as the token to operate core_stream_data to avoid racing issues
   • Ideally we should just change core_stream_data to Mutex<CoreStreamData>, but it's likely to cause deadlocks
   • workaround for above deadlock: Using Mutex<()> for CoreStreamData
     • except callback thread, core_stream_data should only be changed within the thread that locks the a dummy mutex: Mutex<()>
     • to avoid racing with callback thread, just stop the AudioUnit in the right place. Stopping AudioUnit will acquire the same mutex inside AudioUnit that is used when it's data callback is run.

Both approaches can be implemented easily in the current Rust code. From my test, they give similar speeds. They are both around 6x faster than the current Rust implementation, when opening and starting 10 streams at the same time. For opening one stream at a time, the above approaches doesn't bring much benefit.

This problem is not urgent since (I believe) users don't often open multiple streams at the same time. We could fix this when this becomes a real issue. This is more like a note for now.

Make sure the input rate and the output rates are same if the stream is duplex

The cubeb.c disallows to create a duplex stream with different input rates and output rates. However, it's ok to do so in this crate:

https://github.com/ChunMinChang/cubeb-coreaudio-rs/blob/dce7ddc846fb4784b4452f6eda282b67d286e27d/src/backend/tests/interfaces.rs#L487-L499

Aligning the policy here and the policy used in the main cubeb repo makes more sense and causes less confusion. Otherwise, the reader may have different assumptions when reading the code.

A good first step is to add an assertion when initializing the stream.

Fire error callback when non-default output device is unplugged

Now we disable the automatic input device switching when the input device is unplugged. We will fire an error callback and enter an error state if this happens. However, we never monitor the alive status for output device. If the output device doesn't follow the default, then the stream will probably stop working without firing an error callback. Now the cubeb users rely on device-collection changes to know the device is gone.

To align with the policy we have for microphone switching, we should do the same for the output device.

Make mixer become an independent crate

The mixer crate is introduced in #23 to solve the BMO 1468381. The new mixer is able to mix audio from any input layout to any output layout.

The BMO 1368938: mixer only support pre-defined layout on Windows, is probably the same problem of BMO 1468381 so it is likely to be solved by adopting the new mixer on Windows.

Therefore, it's better to make the new mixer crate as an independent crate that can be used to other platforms and make it as a successor of cubeb_mixer.
