Multimedia Format Processing Library is a software module to perform Audio Video parsing/multiplexing of multimedia contents. It is an integral part of any Multimedia-centric application. This module is required to identify the stream type and determine the codecs that need to be instantiated for processing the stream. Present Multimedia Format Processing Library provides the following functionalities: Parsing multiplexing content headers, de-multiplexing compressed Audio, Video and Meta Data. The library also extracts associated timing information and performs time-stamp interpolation. AVFilePlayBack is an application level wrapper provided along with Multimedia Format Processing Library, which encapsulates Multimedia Format Processing Library (MPEG-TS and MPEG-PS) and other format parsers (MP4 and ASF).
