  • * The callback when recording is stopped.

    Declaration

    Objective-C

    - (void)recorderDidStopRecording;

  • * The callback when the maximum recording duration will reach. API_AVAILABLE(3.26.0)

    Declaration

    Objective-C

    - (void)recorderWillStopWithMaxDuration;

  • * The callback when the maximum recording duration is reached.

    Declaration

    Objective-C

    - (void)recorderOutputVideoRawSampleBuffer:(CMSampleBufferRef)sampleBuffer;

    Parameters

    sampleBuffer

    Video data.

  • * The callback that outputs the original audio data.

    Declaration

    Objective-C

    - (void)recorderOutputAudioRawSampleBuffer:(CMSampleBufferRef)sampleBuffer;

    Parameters

    sampleBuffer

    Audio data.

custom render

  • * The callback for custom rendering. CVPixelBufferRef -> CVPixelBufferRef

    Declaration

    Objective-C

    - (CVPixelBufferRef)customRenderedPixelBufferWithRawSampleBuffer:
    (CMSampleBufferRef)sampleBuffer;

    Parameters

    sampleBuffer

    The original video data.

    Return Value

    The PixelBuffer after custom rendering is applied.

  • * The callback for custom rendering. CVPixelBufferRef -> Texture

    Declaration

    Objective-C

    - (int)customRenderedTextureWithRawSampleBuffer:(CMSampleBufferRef)sampleBuffer;

    Parameters

    sampleBuffer

    The original video data.

    Return Value

    The texture after custom rendering is applied.

  • * The callback for custom rendering. Original Texture -> Texture

    Declaration

    Objective-C

    - (int)customRender:(int)srcTexture size:(CGSize)size;

    Parameters

    srcTexture

    The texture id of the original video.
    size

    The texture size of the original video.

    Return Value

    The texture id after custom rendering is applied.

  • Undocumented

    Declaration

    Objective-C

    - (void)destroyRender;

deprecated

  • Deprecated

    deprecated,use customRenderedTextureWithRawSampleBuffer: instead

    * The callback for custom rendering.

    Original video data and texture id are provided for custom rendering. Video data must be in BGRA format.

    Declaration

    Objective-C

    - (NSInteger)recorderOutputVideoPixelBuffer:(CVPixelBufferRef)pixelBuffer
                                textureName:(NSInteger)textureName;

    Parameters

    pixelBuffer

    The data captured by the camera.
    textureName

    The original texture id.

    Return Value

    The texture id after custom rendering is applied.

  • Deprecated

    deprecated, use customRender:size: instead

    * The callback that outputs the video texture returned by the camera.

    This callback must be implemented when the video data is in BGRA or YUV format.

    Declaration

    Objective-C

    - (NSInteger)recorderOutputVideoTextureName:(NSInteger)textureName
                                textureSize:(CGSize)textureSize;

    Parameters

    textureName

    The original texture id.

    Return Value

    The texture id after rendering.

  • Deprecated

    deprecated

    * The callback that outputs the video texture returned by the camera.

    This callback must be implemented when the video data is in YUV format.

    Declaration

    Objective-C
