aes67-visualization

Command line tool to easily launch ffmpeg audio visualizations from AES67 sdp files

Installation

git clone https://github.com/philhartung/aes67-visualization.git
cd aes67-visualization
npm install

In addition to that, both gstreamer (there is some issue with L24BE used in AES67 and ffmpeg, thats why gstreamer is used to convert audio) and ffmpeg need to be installed.
