Watch videos with friends using WebRTC, let your backend do the pausing and seeking.

Using Pion WebRTC and GStreamer you can now watch videos in real-time with your friends. Watch your favorite movie perfectly synchronized with multiple viewers. If someone pauses it pauses for everyone, and no one can and no one fast forward only their video.


rtwatch is different then any other solution because all state is stored on the backend. Only the current audio/video frame is being sent to the viewers, there is no way they can download/cache the videos either for future usage.


Install GStreamer


sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-good

Windows MinGW64/MSYS2

pacman -S mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-libav mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad mingw-w64-x86_64-gst-plugins-ugly


brew install gst-plugins-good pkg-config && export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig

Download rtwatch

go get github.com/pion/rtwatch

Play your video

rtwatch -container-path=/home/sean/video.mp4
> Video file '/home/sean/video.mp4' is now available on ':8080', have fun!

Watch your video with friends!

Open http://localhost:8080 and hit play. Open it in multiple tabs so you can see how it syncs between multiple viewers.

You also have the option to Seek/Play/Pause! Press those buttons and watch the video state change for every viewer at the same time.
