Title
(EN) System and method of processing MPEG streams for file index insertion
Abstract
(EN)
A method, apparatus and article of manufacture is provided for automatic insertion of a compressed GOP offset table within a previously encoded MPEG video file, for frame accurate random access of each individual video frame in play-from-offset mode. The method creates a compressed GOP offset table having an entry for each GOP header of every video packet of the MPEG video file, and modifies the MPEG video file by inserting the compressed GOP offset table before the MPEG video file as at least one padding packet, thereby preserving the MPEG compliance and compressed audio/video data of the MPEG video file. The method further has a step for estimating a number of padding packets needed for the GOP offset table, thereby limiting the MPEG video file reading to a single read.
