GMixer

Graphical frontend for GStreamer pipeline editing. Still very incomplete, but I'm working on it!

Dependencies

This project uses GStreamer and GTK4 (the C++ gtkmm bindings to be exact). GStreamer plugins are dynamically discovered. Building is done via meson, so it should take care of finding all the dependencies in your system, if they are installed.

Building from source

On Linux, so the following to build the project in release mode:

  git clone https://github.com/flowln/GMixer
  cd GMixer
  meson build
  cd build
  meson configure -Dbuildtype=release
  ninja

You will end up with a gmixer file in the build directory. To install it on your system, you can either copy the binary to /usr/bin (or other folter in your PATH variable), or you can do meson install right after the ninja command.

TODO

• Documentation!!!
• Save pipeline to file
• Handle ghost bins (e.g. decodebin's source pads)
• Allow creating more pads when possible
• Show pad caps on the graph
• Check caps when trying to link two pads (and tell the user when it's not possible to link two pads)
• Add keyboard shortcuts (quit, save, import, select node, move node, etc)
• Specialize property edit fields (e.g. checkbox for gboolean properties)
• Improve graph visuals
• Optimize memory usage
• Add DBus support? (for starting pipelines from other processes)
• Generalize basic components (allowing for non-GTK implementations, like a console one)
• Simplify code (since it's my first time using C++ and doing a graphical application, it's highly possible that most things are over-complicated and bad)
