GXF/LXF Reader DirectShow filter for read and demultiplex GXF and LXF files.
Overview
The GXF/LXF Reader 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, or DV video compression standards with PCM audio, time code, and user data that may include user-defined metadata.
Features
