XReader DirectShow filter for read and demultiplex GXF and LXF files.
Overview
The XReader filter is used for playback of GXF and LXF files. It accepts data in GXF or LXF format and demultiplexes it into its DV-DIF, MPEG-2 Video, PCM Audio data streams for further processing and/or rendering.
General eXchange Format (GXF) is a container format designed for transfer of simple and compound clips between television program storage systems. It can contain Motion JPEG (M-JPEG), MPEG-2, H.264/AVC Video Decoder, or DV Decoder video compression standards with PCM audio, time code, and user data that may include user-defined metadata.
