This plugin allows for the creation of virtual c

amera devices that stream output from X11 virtual desktop environments. Each device created by this plugin is a virtual display running a configurable terminal program under xterm. Terminal sizes and fonts can be configured for each virtual display. Several dependency packages are required to set up the virtual camera devices, listed below.
For Scrypted installs on Docker or LXC, the required dependencies are the same as on local Linux, however will be installed automatically at plugin launch.
For local Scrypted installs on Linux, several system packages must be manually installed: xvfb, xterm, xfonts-base. The optional dependency fontconfig can be installed to enable changing fonts.
For local Scrypted installs on MacOS, several brew packages must be manually installed: xquartz, gnu-getopt, ffmpeg.
For local Scrypted installs on Windows, Cygwin will be automatically installed to handle the virtual X11 display.
By default, this plugin requests that the Rebroadcast plugin use the FFmpeg arguments -c:v libx264 -preset ultrafast -bf 0 -r 15 -g 60 for encoding H264 video from the virtual X11 display (libopenh264 is used on Windows instead of libx264). To enable hardware acceleration, copy the above into the "FFmpeg Output Prefix" settings for the stream, replacing libx264 with the hardware-accelerated encoder for your platform. Note that for Windows, the encoder must be one supported within Cygwin.
