Thank you for developing this plug-in. After weeks of research and experimentation, this is the first thing that works for me to bring in multiple sources including PTZ camera and Android phones, and synchronizing all of the RTSP inputs!
This plugin is amazing. Opens up endless sources from where you can bring in video or audio into OBS. For example this plugin gives the ability to get ultra low latency RTSP streaming (From my testing even lower than NDI)
Works great for me under Arch Linux and gives advanced users many possibilities through gstreamer's capabilities. In my opinion, this should be integrated into OBS – it's a great addition to the ffmpeg and VLC based inputs.
