Class Buffer​Capturer 

public class BufferCapturer: VideoCapturer

A VideoCapturer that can capture CMSampleBuffers.

Repeatedly call capture(_:) to capture a stream of CMSampleBuffers. The pixel format must be one of VideoCapturer/supportedPixelFormats. If an unsupported pixel format is used, the SDK will skip the capture. BufferCapturer can be used to provide video buffers from ReplayKit.

Note: At least one frame must be captured before publishing the track or the publish will timeout, since dimensions must be resolved at the time of publishing (to compute video parameters).
