This CL introduced 2 new macros that affect the WebRTC OBJC API symbols: - RTC_OBJC_TYPE_PREFIX: Macro used to prepend a prefix to the API types that are exported with RTC_OBJC_EXPORT. Clients can patch the definition of this macro locally and build WebRTC.framework with their own prefix in case symbol clashing is a problem. This macro must only be defined by changing the value in sdk/objc/base/RTCMacros.h and not on via compiler flag to ensure it has a unique value. - RCT_OBJC_TYPE: Macro used internally to reference API types. Declaring an API type without using this macro will not include the declared type in the set of types that will be affected by the configurable RTC_OBJC_TYPE_PREFIX. Manual changes: https://webrtc-review.googlesource.com/c/src/+/173781/5..10 The auto-generated changes in PS#5 have been done with: https://webrtc-review.googlesource.com/c/src/+/174061.

// Verifies that the AudioDeviceIOS is_interrupted_ flag is reset correctly
|
|
// after an iOS AVAudioSessionInterruptionTypeEnded notification event.
|
|
// AudioDeviceIOS listens to RTC_OBJC_TYPE(RTCAudioSession) interrupted notifications by:
|
|
// - In AudioDeviceIOS.InitPlayOrRecord registers its audio_session_observer_
|
|
// callback with RTC_OBJC_TYPE(RTCAudioSession)'s delegate list.
|
|
// - When RTC_OBJC_TYPE(RTCAudioSession) receives an iOS audio interrupted notification, it
|
|
// passes the notification to callbacks in its delegate list which sets
|
|
// AudioDeviceIOS's is_interrupted_ flag to true.
|
|
// - When AudioDeviceIOS.ShutdownPlayOrRecord is called, its
|
|
// audio_session_observer_ callback is removed from RTCAudioSessions's
|
|
// delegate list.
|
|
// So if RTC_OBJC_TYPE(RTCAudioSession) receives an iOS end audio interruption notification,
|
|
// AudioDeviceIOS is not notified as its callback is not in RTC_OBJC_TYPE(RTCAudioSession)'s
|
|
// delegate list. This causes AudioDeviceIOS's is_interrupted_ flag to be in
|
|
// the wrong (true) state and the audio session will ignore audio changes.
|
|
// As RTC_OBJC_TYPE(RTCAudioSession) keeps its own interrupted state, the fix is to initialize
|
|
// AudioDeviceIOS's is_interrupted_ flag to RTC_OBJC_TYPE(RTCAudioSession)'s isInterrupted
|
|
// flag in AudioDeviceIOS.InitPlayOrRecord.
