Hello, we successfully managed to get video stream into Gem/pix_video with v4l2loopback booth with gstreamer and ffmpeg, we used ffmpeg at the end, maybe some help by there : http://wiki.labomedia.org/index.php/AstroFluxTechnique#Pour_Debug http://wiki.labomedia.org/index.php/AstroFluxTechnique#Minicaster_Stream we used a compiled version of v4l2loopback https://github.com/umlaeute/v4l2loopback to get the latest version and a static version of ffmpeg or a self compiled version of ffmpeg in function of the codec needs
