GXF/LXF Reader

DirectShow filter for reading and demultiplexing 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

Supports reverse playback for DV and PCM Audio tracks.

Specifications and description of user interfaces can be found in the .idl file in the \Idl folder of the filter installation directory.
