Videomaster Fork of FFmpeg README

FFmpeg is a collection of libraries and tools for processing multimedia content such as audio, video, subtitles, and related metadata.

About This Fork

This repository is a fork of FFmpeg with a custom demuxer added to support DELTACAST (c) PCIe capture cards via the VideoMaster SDK. The main addition is the videomaster input device, which allows FFmpeg to capture video and audio streams directly from supported DELTACAST hardware.

Building with videomaster Support

To enable the videomaster demuxer, configure FFmpeg with the --enable-videomaster option in the configure command line.

You must also have the DELTACAST VideoMaster SDK installed and provide the appropriate --extra-c[xx]flags to specify the path to the SDK's public headers, and --extra-ldflags to specify the path to the SDK libraries.

An example configure command line is:

configure --enable-gpl --enable-nonfree --enable-videomaster --extra-cflags="-I../../install/videomaster/win64/include" --extra-cxxflags="-I../../install/videomaster/win64/include" --extra-ldflags="-LIBPATH:../../install/videomaster/win64/lib"

Usage

Once built, you can use the videomaster input device in FFmpeg commands to capture from DELTACAST cards. For example:

ffmpeg -f videomaster -i "stream 0 on board 0" output.avi

See the Input Devices documentation for detailed usage and options.

Documentation
