The EncodedVideoChunk() constructor creates a new EncodedVideoChunk object representing a chunk of encoded video.
new EncodedVideoChunk(options)
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.
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);
