1. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the device to:
receive, at a first bitrate, at least one segment of a first variant, wherein the at least one segment of the first variant comprises stream access points (SAPs) of a first type that do not reset a picture reference buffer;
send a request for segments encoded at a second bitrate; and
receive, at the second bitrate, a segment, of a second variant, that comprises a SAP of a second type that does reset the picture reference buffer, and a next segment of the second variant comprising a SAP of the first type.
