cmake . (or “cmake -DZOOMFIX=ON .” to get a screen-sharing fix to make X11 mirror display windows visible to screen-sharing applications such as Zoom, see Improvements #3 below). ZOOMFIX is only needed for GStreamer-1.18.x or earlier.makesudo make install (you can afterwards uninstall with sudo make uninstall in the same directory in which this was run)sudo apt-get install gstreamer1.0-<plugin>; values of <plugin> needed are: “plugins-base”, “libav” (for sound), “plugins-good” (for v4l2 hardware h264 decoding) and “plugins-bad” (for h264 decoding). Also needed may be “gl” for OpenGL support (which may be useful, and should be used with h264 decoding by the NVIDIA GPU), and “x” for X11 support, although these may already be installed; “vaapi” is needed for hardware-accelerated h264 video decoding by Intel graphics (not for NVIDIA). Also install “tools” to get the utility gst-inspect-1.0 for examining the GStreamer installation.sudo apt-get install gstreamer1.0-<plugin>; values of <plugin> needed are: “plugins-base”, “libav” (for sound), “plugins-good” (for v4l2 hardware h264 decoding) and “plugins-bad” (for h264 decoding).

The above script installs the executable file “uxplay” to /usr/local/bin, (and installs a manpage to somewhere like /usr/local/share/man/man1 and README files to somewhere like /usr/local/share/doc/uxplay). It can also be found in the build directory after the build processs.
