Video processing using multiple bitstream engines

A method comprising:

• receiving, at a device, a bitstream representing a plurality of video frames;
• decoding, at a first bitstream engine of the device, bits associated with a first portion of a first video frame of the plurality of video frames to generate first decoded portion data;
• generating, at the first bitstream engine, synchronization information based on completion of decoding of the bits associated with the first portion;
• initiating decoding, at a second bitstream engine of the device, of bits associated with a second portion of a particular video frame to generate second decoded portion data, the decoding of the bits associated with the second portion based on the synchronization information and the first decoded portion data, wherein the particular video frame includes the first video frame or a second video frame of the plurality of video frames;
• and
• initiating decoding, at the first bitstream engine, of bits associated with a third portion of the first video frame while the second bitstream engine is decoding the bits associated with the second portion of the particular video frame, wherein the third portion of the first video frame is distinct from the first portion of the first video frame.

A device comprising:

• an interface configured to receive a plurality of video frames;
• a first bitstream engine configured to encode first portion data of a first portion of a first video frame of the plurality of video frames to generate bits associated with a first encoded portion and configured to generate synchronization information based on completion of encoding the first portion;
• and
• a second bitstream engine configured to, based on the synchronization information, initiate encoding of second portion data of a second portion of a particular video frame to generate bits associated with a second encoded portion, wherein the second bitstream engine uses the first encoded portion during encoding of the second portion of the particular video frame, and wherein the particular video frame includes the first video frame or a second video frame of the plurality of video frames,
• wherein the first bitstream engine is further configured to encode a third portion of the first video frame while the second bitstream engine encodes the second portion of the particular video frame, wherein the third portion of the first video frame is distinct from the first portion of the first video frame.

• and
• initiating encoding, at the first bitstream engine, of a third portion of the first video frame while the second bitstream engine is encoding the second portion of the particular video frame, wherein the third portion of the first video frame is distinct from the first portion of the first video frame.
