AVStreamGroupLayeredVideo is meant to define the relation between a base layer video stream and a separate enhancement layer stream that together form a single layered video presentation (for example a video stream and a data stream containing LCEVC enhancement layer NALUs, Dolby Vision Profile 7 dual-layer encoding, or a base rendition accompanied by an ISO 21496-1 gain map).

Detailed Description

AVStreamGroupLayeredVideo is meant to define the relation between a base layer video stream and a separate enhancement layer stream that together form a single layered video presentation (for example a video stream and a data stream containing LCEVC enhancement layer NALUs, Dolby Vision Profile 7 dual-layer encoding, or a base rendition accompanied by an ISO 21496-1 gain map).

The enhancement layer stream is identified by el_index.
