LEAD MPEG2 Program Media Source

Show in webframe

The LEAD MPEG2 Program Media Source is a MediaFoundation transform that can parse the following types of streams:

MPEG-2 Program specified in ISO/IEC 13818-1
MPEG-1 System specified in ISO/IEC 11172-1
Elementary stream data (also known as raw video or raw audio data)

The first two formats are multiplexed formats, and they can contain video, audio and private data streams. The video compression can be MPEG1 (ISO/IEC 11172-2), MPEG2 (ISO/IEC 13818-2), MPEG4 (ISO/IEC 14496-2) or H.264 (ISO/IEC 14496-10). The audio compression can be MPEG1 (ISO/IEC 11172-3), AC3, LPCM or AAC.

This transform does NOT support MPEG-2 Transport streams defined in ISO/IEC 13818-1. Those streams are supported in the LEAD MPEG2 Transport Media Source.

This transform does NOT support private data. For private data support, please use the LEAD MPEG2 Transport Media Source.
