cl.multimedia.1 Changed the Declaration of the Focus Event Callback of Audio Renderer C APIs

For the audio renderer C APIs of API version 10, the focus event callback is changed from OH_AudioRenderer_OnInterrptEvent to OH_AudioRenderer_OnInterruptEvent.

Change Impact

Applications that use the involved APIs may have compatibility issues.

Key API/Component Changes

Before change:

int32_t (*OH_AudioRenderer_OnInterrptEvent)(
       OH_AudioRenderer* renderer,
       void* userData,
       OH_AudioInterrupt_ForceType type,
       OH_AudioInterrupt_Hint hint);

After change:

int32_t (*OH_AudioRenderer_OnInterruptEvent)(
       OH_AudioRenderer* renderer,
       void* userData,
       OH_AudioInterrupt_ForceType type,
       OH_AudioInterrupt_Hint hint);

Adaptation Guide

To define the focus event for an audio renderer, use the function pointer OH_AudioRenderer_OnInterruptEvent. Example:

Before change:

OH_AudioRenderer_Callbacks callbacks;
callbacks.OH_AudioRenderer_OnInterrptEvent = AudioRendererOnInterrptEvent;

After change:

OH_AudioRenderer_Callbacks callbacks;
callbacks.OH_AudioRenderer_OnInterruptEvent = AudioRendererOnInterrptEvent;

cl.multimedia.2 Changed the Declaration of the Focus Event Callback of Audio Capturer C APIs

For the audio capturer C APIs of API version 10, the focus event callback is changed from OH_AudioCapturer_OnInterrptEvent to OH_AudioCapturer_OnInterruptEvent.

Change Impact

Applications that use the involved APIs may have compatibility issues.

Key API/Component Changes

Before change:

int32_t (*OH_AudioCapturer_OnInterrptEvent)(
       OH_AudioCapturer* renderer,
       void* userData,
       OH_AudioInterrupt_ForceType type,
       OH_AudioInterrupt_Hint hint);

After change:

int32_t (*OH_AudioCapturer_OnInterruptEvent)(
       OH_AudioCapturer* capturer,
       void* userData,
       OH_AudioInterrupt_ForceType type,
       OH_AudioInterrupt_Hint hint);

Adaptation Guide

To define the focus event for an audio capturer, use the function pointer OH_AudioCapturer_OnInterruptEvent. Example:

Before change:

OH_AudioCapturer_Callbacks callbacks;
callbacks.OH_AudioCapturer_OnInterrptEvent = AudioCaptureOnInterruptEvent;

After change:

OH_AudioCapturer_Callbacks callbacks;
callbacks.OH_AudioCapturer_OnInterruptEvent = AudioCaptureOnInterruptEvent;
