Overview
An object supporting video data in two formats; pixel buffer and raw data.
When the video source is initialized, the media engine passes this object to you and you need to reserve it, and then pass the video frame to the media engine through this object once the video source is initialized. Call bufferType to specify a buffer type. The video data can only be transmitted in the corresponding type.
– consumePixelBuffer:withTimestamp:rotation:
required method
Uses the video information in the pixel buffer.
- (void)consumePixelBuffer:(CVPixelBufferRef _Nonnull)pixelBuffer withTimestamp:(CMTime)timestamp rotation:(AgoraVideoRotation)rotationParameters
pixelBuffer |
Buffer type |
|---|---|
timestamp |
Timestamp (ms) of the video frame. For each video frame, you need to set a timestamp. |
rotation |

– consumeRawData:withTimestamp:format:size:rotation:
required method
Uses the video information in the raw data.
- (void)consumeRawData:(void *_Nonnull)rawData withTimestamp:(CMTime)timestamp format:(AgoraVideoPixelFormat)format size:(CGSize)size rotation:(AgoraVideoRotation)rotationParameters
rawData |
Raw data of the video frame. |
|---|---|
timestamp |
Timestamp (ms) of the video frame. |
format |
|
size |
Size of the raw video data. |
