Media Subsystem ChangeLog

cl.media.1 API Change of the Playback Function

Added the AVPlayer9+ API for audio and video playback, with the updated state machine and error codes, which is recommended. The following APIs for audio playback and video playback are no longer maintained: AudioPlayer6+ and VideoPlayer8+.

Change Impacts

The original APIs can still be used but are no longer maintained. You are advised to use the new API instead.

cl.media.2 API Change of the Recording Function

Added the AVRecorder9+ API for audio and video recording, with the updated state machine and error codes, which is recommended. The following APIs for audio recording and video recording are no longer maintained: AudioRecorder6+ and VideoRecorder9+.

The AudioSourceType and VideoSourceType APIs shared by the old and new recording APIs are changed to non-system APIs.

Change Impacts

The AudioRecorder6+ and VideoRecorder9+ APIs can still be used but are no longer maintained. You are advised to use the AVRecorder9+ API instead.
