# GStreamer command-line cheat sheet
2018-02-20 12:23:23 +00:00
2018-03-05 20:22:50 +00:00
This series of docs provides a cheat sheet for GStreamer on the command-line.
2018-06-08 20:35:46 +00:00
A few Python examples are also [included ](python_examples/ ) for when you need GStreamer to be dynamic (i.e. react to user or some other action).

## Interacting with the GStreamer pipeline
2018-02-25 17:16:08 +00:00
2018-04-03 21:51:32 +00:00
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:
2018-02-25 17:16:08 +00:00
* *[GStreamer Daemon (gstd)](https://github.com/RidgeRun/gstd-1.x)* - allows setting and updating via a TCP connection
2018-06-04 17:02:31 +00:00
* *[Snowmix](http://snowmix.sourceforge.net/)* - an open-source live video mixer
2018-02-25 17:16:08 +00:00
* *Develop using the GStreamer library*, in either [C ](https://gstreamer.freedesktop.org/documentation/application-development/basics/helloworld.html ), [Python ](https://github.com/GStreamer/gst-python ), or [C#/.NET ](https://github.com/GStreamer/gstreamer-sharp )
### Python with GStreamer
2018-06-08 20:35:46 +00:00
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/ ](python_examples/ ) directory.
Other good GStreamer Python resources that I've found:

# My GStreamer project
Creating this guide gave me enough GStreamer understanding to make [Brave ](https://github.com/bbc/brave ), a live video editor for the cloud.
