摘要:
A device includes a first bitstream engine and a second bitstream engine. The first bitstream engine is configured to decode a first portion of a first video frame of a plurality of video frames to generate first decoded portion data. The first bitstream engine is also configured to generate synchronization information based on completion of decoding the first portion. The second bitstream engine is configured to, based on the synchronization information, initiate decoding of a second portion of a particular video frame to generate second decoded portion data. The second bitstream engine uses the first decoded portion data during decoding of the second portion of the particular video frame. The particular video frame includes the first video frame or a second video frame of the plurality of video frames.
