gstreamer-video-streaming

Example C application utilising GStreamer to mix 3 videos onto one screen and optionally stream the result to Twitch via RTMP.

Tested on Ubuntu 20.04.

Features

• Mixing 3 videos into one screen (which size can be configured)
• optional Twitch streaming
• core functionality is wrapped inside a GObject class, allowing for usage outside of C

Usage

ThreeVideoStream object encapsulates all the functionality and exposes a set of properties that can affect the playback. Optional properties should be set before the property ready-to-play is set.

Note: ThreeVideoStream exposes GstPipeline * as one of its properties to allow state monitoring & state changes of the underlying GStreamer pipeline.

Roadmap

• add audio support
• implement more layouts (and expose a enum property to change them at runtime)
• allow building on MacOS & Windows
• add GUI controls (GTK)
• allow dynamically reconfiguring the pipeline
• add support for streaming to other RMTP services
• rewrite in Rust :)
