GStreamer command-line cheat sheet

This series of docs provides a cheat sheet for GStreamer on the command-line.

A few Python examples are also included for when you need GStreamer to be dynamic (i.e. react to user or some other action).

Contents

• Basics
• Test streams
• RTMP
• Mixing video & audio
• Images
• Queues
• Capturing images
• Sending to multiple destinations (tee)
• Sharing and receiving pipelines, including sending/receiving video from shared memory
• Network transfer (including how to send so that VLC can preview)

Sources and references

• Basic command line reference
• Pipeline examples
• List of all Gstreamer plugins
• Handy elements

Interacting with the GStreamer pipeline

If you want to interact with GStreamer after it's started (e.g. respond to an event, or dynamically change a pipeline), the command-line GStreamer doesn't really cut it. Instead, here are some options:

• GStreamer Daemon (gstd) - allows setting and updating via a TCP connection
• Snowmix - an open-source live video mixer
• Develop using the GStreamer library, in either C, Python, or C#/.NET

Python with GStreamer

Python is an easy language, so it's no surprise that it's good way to develop using GStreamer.

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

Other good GStreamer Python resources that I've found:

• Getting started with GStreamer with Python
• Python GStreamer Tutorial
• Function reference
• Nice example script

C/C++ with GStreamer

My favourite reference is Valadoc
