EncodedVideoChunk.type

The type read-only property of the EncodedVideoChunk interface returns a value indicating whether the video chunk is a key chunk, which does not rely on other frames for decoding.

A string, one of:

"key"

The data is a key chunk.

"delta"

The data is not a key chunk.

In the following example the type is printed to the console.

const init = {
  type: 'key',
  data: videoBuffer,
  timestamp: 23000000,
  duration: 2000000
};
chunk = EncodedVideoChunk(init);

console.log(chunk.type); //"key"
