EncodedVideoChunk: EncodedVideoChunk() constructor

Syntax

new EncodedVideoChunk(options)

Parameters

options

An object containing the following members:

type

Indicates if the chunk is a key chunk that does not rely on other frames for encoding. One of:

"key"

The data is a key chunk.

"delta"

The data is not a key chunk.

timestamp

An integer representing the timestamp of the video in microseconds.

duration

An integer representing the length of the video in microseconds.

data

An ArrayBuffer, a TypedArray, or a DataView containing the video data.

transfer

An array of ArrayBuffers that EncodedVideoChunk will detach and take ownership of. If the array contains the ArrayBuffer backing data, EncodedVideoChunk will use that buffer directly instead of copying from it.

Examples

In the following example a new EncodedVideoChunk is created.

const init = {
  type: "key",
  data: videoBuffer,
  timestamp: 23000000,
  duration: 2000000,
  transfer: [videoBuffer],
};
chunk = new EncodedVideoChunk(init);
