Abstract
Techniques are described for split processing of streaming segments in which processing operations are split between a source component and a decoder component. For example, the source component can perform operations for receiving a streaming segment, demultiplexing the streaming segment to separate a video content bit stream, scanning the video content bit stream to find a location at which decoding can begin (e.g., scanning up to a first decodable I-picture, for which header parameter sets are available for decoding), and send the video content bit stream to the decoder component beginning at the location (e.g., the first decodable I-picture). The decoder component can begin decoding at the identified location (e.g., the first decodable I-picture). The decoder component can also discard subsequent pictures that reference a reference picture not present in the video content bit stream (e.g., when decoding starts with a new streaming segment).
