How to create RTCVideoFrame?

In Banuba SDK, you can create RTCVideoFrame from a CVPixelBuffer that could be received from startForwardingFrames method

sdkManager.output?.startForwardingFrames(handler: { (pixelBuffer) -> Void in

            let rtcpixelBuffer = RTCCVPixelBuffer(pixelBuffer: pixelBuffer)

            videoFrame = RTCVideoFrame(

                buffer: rtcpixelBuffer,

                rotation: RTCVideoRotation._0,

                timeStampNs: Int64(timestamp)

            )

        })
