1. An apparatus for decoding a bitstream, comprising:
at least one processor; and
at least one computer-readable medium storing instructions executable by the at least one processor to perform operations comprising:
receiving the bitstream, wherein the bitstream includes image frames associated with at least a first temporal scalability level and a second temporal scalability level,
wherein the image frames of the second temporal scalability level are not used as a reference for motion-compensated prediction of the image frames of the first temporal scalability level,
wherein at least one frame of the second temporal scalability level is signaled in the bitstream by an encoder as a disposable frame, and at least one frame of the second temporal scalability level is signaled in the bitstream by the encoder as a non-disposable frame, and
wherein the second temporal scalability level comprises at least one frame that is an I-coded picture, and at least one frame that is not an I-coded picture;
discarding, based on signaling in the bitstream and without decoding, all frames of the second temporal scalability level, including the at least one frame that is signaled in the bitstream by the encoder as a disposable frame, and the at least one frame that is signaled in the bitstream by the encoder as a non-disposable frame; and
decoding frames of the first temporal scalability level.
