摘要： In one embodiment, a method for reordering video packets from a multiplexed video bitstream is implemented on a computing device and includes: defining a current program identifier (PID), receiving the video packets, where each of the video packets is associated with an associated PID and a next-PID indication, for each video packet from among the received video packets, checking whether the associated PID is equal to the current PID, upon determining that the associated PID is equal to the current PID, appending the video packet as an output video packet to a reordered video bitstream, upon determining that the associated PID is not equal to the current PID, queueing the video packet as a queued video packet in a PID queue associated with the associated PID, and updating the current PID in accordance with the next-PID indication from a most recently appended output video packet in the reordered video bitstream.
