Pipelines consist of linked elements.
- Sink (file, net, screen, etc)
- Demux, tee
$ gst-launch-1.0 filesrc location=video.ogv ! oggdemux ! theoradec ! autovideosink
playbin - just play file = mplayer
Probably about 100 media players in world that are based on gstreamer
Muxer: combining 2 streams into 1 file.
Really good example - video wall.
Decode bin -> split into 4 streams (tee) -> queues (often freezes as all running in 1 thread and bump into eachother) -> crop (I.e. Remove 3/4s of video). And also play audio.
Can just use gstreamer cli syntax when calling gi calls in Python.
