GXF Splitter


GXF splitter (demultiplexer) DirectShow filter.

Overview

The GXF (General eXchange Format) Splitter (demultiplexer) filter is used for playback of GXF files. It accepts data in GXF format and demultiplexes it into its DV-DIF, MPEG-2 Video, PCM Audio data streams for further processing and/or rendering. This filter is typically connected to the Async File Source filter on its input pin, although it can connect to any filter that has an output pin that supports IAsyncReader.

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, or DV video compression standards with PCM audio, time code, and user data that may include user-defined metadata.

  • Supports reverse playback for DV and PCM Audio tracks.
