GStreamer command-line cheat sheet

GStreamer is a powerful library for manipulating audio and video - including live streams. This repo provides:

  • a few Python examples.

Whilst the command line is great, programmatic usage (in Python or another language) allows you to dynamically manipulate the A/V streams.

Some example scripts can be found in the python_examples/ directory.

Other good GStreamer Python resources that I've found:

C/C++ with GStreamer

My GStreamer project

Creating this guide gave me enough GStreamer understanding to make a prototype Brave, a live video editor for the cloud. (Regrettably this prototype has not been updated in a few years.)
