# Media Subsystem ChangeLog

## cl.media.1 API Change of the Playback Function

Added the [AVPlayer](../../../application-dev/reference/apis/js-apis-media.md#avplayer9)<sup>9+</sup> 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 The following APIs for audio playback and video playback are no longer maintained: [AudioPlayer](../../../application-dev/reference/apis/js-apis-media.md#audioplayer)<sup>6+</sup> and [VideoPlayer](../../../application-dev/reference/apis/js-apis-media.md#videoplayer)<sup>8+</sup>.

**Change Impacts**

The original APIs can still be used but are no longer maintained.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

**Adaptation Guide**

For details, see the [reference](../../../application-dev/reference/apis/js-apis-media.md) for each API.

## cl.media.2 API Change of the Recording Function

Added the [AVRecorder](../../../application-dev/reference/apis/js-apis-media.md#avrecorder9)<sup>9+</sup> 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 The following APIs for audio recording and video recording are no longer maintained: [AudioRecorder](../../../application-dev/reference/apis/js-apis-media.md#audiorecorder)<sup>6+</sup> and [VideoRecorder](../../../application-dev/reference/apis/js-apis-media.md#videorecorder9)<sup>9+</sup>.

The [AudioSourceType](../../../application-dev/reference/apis/js-apis-media.md#audiosourcetype9) and [VideoSourceType](../../../application-dev/reference/apis/js-apis-media.md#videosourcetype9) APIs shared by the old and new recording APIs are changed to non-system APIs.

**Change Impacts**

The [AudioRecorder](../../../application-dev/reference/apis/js-apis-media.md#audiorecorder)<sup>6+</sup> and [VideoRecorder](../../../application-dev/reference/apis/js-apis-media.md#videorecorder9)<sup>9+</sup> APIs can still be used but are no longer maintained. You are advised to use the [AVRecorder](../../../application-dev/reference/apis/js-apis-media.md#avrecorder9)<sup>9+</sup> API instead.

**Adaptation Guide**

For details, see the [reference](../../../application-dev/reference/apis/js-apis-media.md) for each API.

## cl.media.3 Error Code Change

Added the standard error code enumeration type [AVErrorCode9](../../../application-dev/reference/apis/js-apis-media.md#averrorcode)<sup>9+</sup> that replaces the original error code enumeration type [MediaErrorCode](../../../application-dev/reference/apis/js-apis-media.md#mediaerrorcode)<sup>8+</sup>.

**Change Impacts**

The error code enumeration type [MediaErrorCode](../../../application-dev/reference/apis/js-apis-media.md#mediaerrorcode)<sup>8+</sup> is still used for original APIs. [AVErrorCode9](../../../application-dev/reference/apis/js-apis-media.md#averrorcode)<sup>9+</sup> is used for newly added APIs.
