Abstract
Systems and methods are described herein for processing video. An encoder may generate, for a sequence of video frames, a plurality of first segments and a plurality of second segments. The plurality of first segments may comprise stream access points (SAPs) of a first type that do not reset a picture reference buffer. The plurality of second segments may comprise SAPs of a second type that do reset the picture reference buffer. The encoder may send segments of the plurality of first segments to a computing device streaming video when network conditions are steady. The encoder may send a segment of the plurality of second segments following a switch, by the computing device, to a different bitrate based on a change to the network conditions. Once the computing device has decoded the segment the plurality of second segments, the encoder may send subsequent first segments at the different bitrate.
