用RTCVideoframe创建CVPixelBuffer

Question

创建RTCVideoframe需要帮助

这是RTCVideoframe RTCVideoFrame(buffer: RTCVideoFrameBuffer, rotation: RTCVideoRotation, timeStampNs: Int64)的init方法。

我能够获得输入缓冲区作为CVPixelBuffer

如何将CVpixelBuffer转换为RTCVideoFrameBuffer。

非常感谢您的帮助。

使用我们收到的cmSampleBuffer

`

sharedRecorder.startCapture(handler: { (cmSampleBuffer, rpSampleType, error) in
   switch rpSampleType {
  case RPSampleBufferType.video:

{
 let pixelBuffer = CMSampleBufferGetImageBuffer(cmSampleBuffer)!
 let rtcpixelBuffer = RTCCVPixelBuffer(pixelBuffer: pixelBuffer)
 videoFrame = RTCVideoFrame(buffer: rtcpixelBuffer, rotation: RTCVideoRotation._0, timeStampNs: Int64(timestamp))
}
} )}
