Properties

alpha

alpha?: Uint8Array<ArrayBufferLike>;

An encoded alpha frame, encoded with the same codec as the packet. Typically used for transparent videos, where the alpha information is stored separately from the color information.

alphaByteLength

alphaByteLength?: number;

The actual byte length of the alpha data. This field is useful for metadata-only packets where the alpha field contains no bytes.
