The VideoDecoder() constructor creates a new VideoDecoder object with the provided init.output callback assigned as the output callback, the provided init.error callback as the error callback, and the VideoDecoder.state set to "unconfigured".

options

An object containing two callbacks.

output

A callback which takes a VideoFrame object as its only argument.

error

A callback which takes an Error object as its only argument.

In the following example a VideoDecoder is created with the two required callback functions, one to deal with the decoded frame and the other to handle errors.

const videoDecoder = new VideoDecoder({
  output: processVideo,
  error: onEncoderError,
});
