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).

The Multimedia Format Processing Library can be used to extract one more Audio/Video elementary streams from any one of the following composite streams:

MPEG-TS (ISO/IEC standard 13818-1)

MPEG-PS (ISO/IEC standard 13818-1)

MP4 file format (ISO/IEC 14496-12, 1 and 14)

Advanced Systems Format (ASF) Specification(1.20.03, MS Corporation, December 2004) The Multimedia Format Processing Library also support property extraction and framing for following elementary streams:

ISO/IEC14496-2 (MPEG4 Video )

ISO/IEC14496-10 (AVC Video )

ISO/IEC13818-2 (MPEG2 Video )

ISO/IEC 11172-3, 13818-3 ( MPEG Audio or MP3)

ISO/IEC 13818-7 (MPEG2 AAC)
