OptionalmetricsCallback: (The output MediaStream as a result of processor executions.
It is possible, but unlikely, that this accessor will throw.
The desired output frame rate.
The desired output frame rate.
Lists of processors to execute to produce output media stream.
Lists of processors to execute to produce output media stream.
Adds VideoFrameProcessorPipelineObserver observer to receive lifecycle and performance callback.
Destroys the pipeline, processors, intermediate buffers and input stream.
Returns an active output stream.
Returns the current input MediaStream.
Removes VideoFrameProcessorPipelineObserver observer.
inputMediaStream is by default used to construct one CanvasVideoFrameBuffer
The buffer will be fed into the first VideoFrameProcessor.
Stops the pipeline.
[[DefaultVideoFrameProcessorPipeline]] implements VideoFrameProcessorPipeline. It constructs a buffer CanvasVideoFrameBuffer as source by default and invokes processor based on
framerate. The default output type isMediaStream.When every processor implements VideoFrameProcessor.transformTrack, it chains them instead, until one fails to start or ends its output track; it then replaces the video track of
outputMediaStreamwith the canvas output until it is stopped, and the next input tries the processors again. The metrics callback andprocessingLatencyTooHighare only invoked for the canvas.
