Instance Methods
(void)	- onMobileRTCRender:framePixelBuffer:extraInfo:
	This method is used to receive video's NV12 data (CVPixelBufferRef) together with rich per-frame metadata.
(void)	- onMobileRTCRender:framePixelBuffer:rotation:
	This method is used to receive video's NV12 data(CVPixelBufferRef).
(void)	- onMobileRTCRender:frameRawData:
	This method is used to receive video's YUV420 data.
(void)	- onMobileRTCRender:rawDataSending:
	Callback event when the sender stop/start to sending raw data.

Detailed Description

This class is used to receive video raw data.

Note

The MobileRTCVideoRawDataDelegate protocol is required in the custom meeting UI view.

Method Documentation

onMobileRTCRender:framePixelBuffer:extraInfo:

- (void) onMobileRTCRender: (MobileRTCRenderer *_Nonnull) renderer framePixelBuffer: (CVPixelBufferRef _Nullable) pixelBuffer extraInfo: (MobileRTCVideoPixelBufferExtraInfo *_Nonnull) extraInfo

optional

This method is used to receive video's NV12 data (CVPixelBufferRef) together with rich per-frame metadata.

Prefer this selector over the legacy -onMobileRTCRender:framePixelBuffer:rotation: when you need access to sender-side face ROI metadata or any future per-frame fields. The MobileRTCVideoPixelBufferExtraInfo container is designed to absorb future additions without further selector churn.

Note

If your delegate implements both this selector and the legacy -onMobileRTCRender:framePixelBuffer:rotation: selector, both will be called for every frame. New code should implement only this extraInfo: variant.

Parameters

renderer	The MobileRTCRenderer instance.
pixelBuffer	NV12 CVPixelBufferRef for the frame. The buffer is released by the SDK after this callback returns; call CVPixelBufferRetain to retain it for asynchronous use.
extraInfo	Per-frame metadata container; non-null. See MobileRTCVideoPixelBufferExtraInfo for current fields (rotation, faceROIInfo).

onMobileRTCRender:framePixelBuffer:rotation:

- (void) onMobileRTCRender: (MobileRTCRenderer *_Nonnull) renderer framePixelBuffer: (CVPixelBufferRef _Nullable) pixelBuffer rotation: (MobileRTCVideoRawDataRotation) rotation

optionalrequired

This method is used to receive video's NV12 data(CVPixelBufferRef).

Deprecated

Use -onMobileRTCRender:framePixelBuffer:extraInfo: instead. The new selector delivers the same CVPixelBufferRef along with a MobileRTCVideoPixelBufferExtraInfo container that exposes face ROI metadata and is designed to absorb future per-frame fields without further selector churn. While this legacy selector continues to function, it should not be implemented together with the extraInfo: variant on the same delegate - both would be called for every frame.

Parameters

pixelBuffer	Video's CVPixelBufferRef data.
renderer	The MobileRTCRenderer’s object.

onMobileRTCRender:frameRawData:

- (void) onMobileRTCRender: (MobileRTCRenderer *_Nonnull) renderer frameRawData: (MobileRTCVideoRawData *_Nonnull) rawData

optionalrequired

This method is used to receive video's YUV420 data.

Parameters

rawData	Video's YUV420 data.
renderer	The MobileRTCRenderer’s object.

onMobileRTCRender:rawDataSending:

- (void) onMobileRTCRender: (MobileRTCRenderer *_Nonnull) renderer rawDataSending: (BOOL) on

optionalrequired

Callback event when the sender stop/start to sending raw data.

Parameters

renderer	The MobileRTCRenderer’s object.
on	Raw data is sending or not.
