GStreamer is a pipeline-based multimedia framework that allows processing and streaming multimedia data. It supports many common media formats and codecs through plugins. The talk introduces GStreamer and shows how to build pipelines with elements like decoders and filters to play or convert audio and video files using command line tools or code examples in Python.
