This is the sample code that goes along the FOSDEM talk: Syncronised multi-device media playback with GStreamer
https://fosdem.org/2016/schedule/event/synchronised_gstreamer/
- sudo apt-get install meson ninja-build
- in both leader.c and follower.c
- edit lines g_object_set (playbin, "uri", ...) to point to an existing media file
- meson build
- ninja -C build/
- ./build/leader
- ./build/follower
- as many followers as you would like
