MediaParent.cpp 16123
MediaParent.h Dummy class to avoid a templated class being passed to the refcounting macro (see Bug 1334421 for what happens then) 2775
MediaSystemResourceClient.cpp 1685
MediaSystemResourceClient.h This is a base class for listener callbacks. This callback is invoked when the media system resource reservation state is changed. 2800

MediaTaskUtils.h media::NewTaskFrom() - Create a Task from a lambda. Similar to media::NewRunnableFrom() - Create an nsRunnable from a lambda, but ignore the return value from the lambda. Prefer NS_NewRunnableFunction(), which provides a specific name, unless the lambda really must have a non-void return value that is to be ignored. 1512
MediaUtils.cpp 4613
MediaUtils.h media::NewRunnableFrom() - Create a Runnable from a lambda. Passing variables (closures) to an async function is clunky with Runnable: void Foo() { class FooRunnable : public Runnable { public: FooRunnable(const Bar &aBar) : mBar(aBar) {} NS_IMETHOD Run() override { // Use mBar } private: RefPtr<Bar> mBar; }; RefPtr<Bar> bar = new Bar(); NS_DispatchToMainThread(new FooRunnable(bar); } It's worse with more variables. Lambdas have a leg up with variable capture: void Foo() { RefPtr<Bar> bar = new Bar(); NS_DispatchToMainThread(media::NewRunnableFrom([bar]() mutable { // use bar })); } Capture is by-copy by default, so the nsRefPtr 'bar' is safely copied for access on the other thread (threadsafe refcounting in bar is assumed). The 'mutable' keyword is only needed for non-const access to bar. 10526 3338
OSXRunLoopSingleton.cpp This is needed so that AudioUnit listeners get called on this thread, and not the main thread. If we don't do that, they are not called, or a crash occur, depending on the OSX version. 1442
OSXRunLoopSingleton.h This function tells CoreAudio to use its own thread for device change notifications, and can be called from any thread without external synchronization. 729
PCameras.ipdl 2782
PMedia.ipdl Requests a potentially persistent unique secret key for each principal. Has no expiry, but is cleared by age along with cookies. This is needed by mediaDevices.enumerateDevices() to produce persistent deviceIds that wont work cross-origin. If this OriginAttributes dictionary has the privateBrowsing flag set to false, a key for this origin is returned from a primary pool of temporal in-memory keys and persistent keys read from disk. If no key exists, a temporal one is created. If aPersist is true and key is temporal, the key is promoted to persistent. Once persistent, a key cannot become temporal again. If the OriginAttributes dictionary has the privateBrowsing flag set to true, a different key for this origin is returned from a secondary pool that is never persisted to disk, and aPersist is ignored. 1937
PMediaSystemResourceManager.ipdl The PMediaSystemResourceManager is a sub-protocol in PImageBridge 1047

VideoEngine.cpp 7905
VideoEngine.h Returns a non-negative capture identifier or -1 on failure. @value aOptions can be used to specify options for the new VideoCapture. This option is currently used only with PipeWire implementation and provides access to PipeWire remote for which we were granted permissions. 4549
