VideoDecoder.decode()

The decode() method of the VideoDecoder interface enqueues a control message to decode a given chunk of video.

chunk

An EncodedVideoChunk object representing a chunk of encoded video.

Undefined.

InvalidStateError DOMException

Thrown if the state is not configured.

DataError DOMException

Thrown if the chunk is unable to be decoded due to relying on other frames for decoding.

The following example demonstrates how to use the decode() method to decode EncodedVideoChunk objects created from encoded video data.

let responses = await downloadVideoChunksFromServer(timestamp);
for (let i = 0; i < responses.length; i++) {
  let chunk = new EncodedVideoChunk({
    timestamp: responses[i].timestamp,
    data: new Uint8Array ( responses[i].body )
  });
  decoder.decode(chunk);
}
