S-frame (Switching Frame) was added to the AV1 video encoder to allow shorter segments in ABR, enabling low latency live streaming without the burden of using bit-consuming IDR frames. Segments will be allowed to start with S-frame and video player could switch, decode and play at any segment boundary. This talk will cover specifics of S-frame and show how up to 20% bitrate savings could be achieved on top of AV1 encoder.
