+A faster method of creating the proxy file outiside of \CGG{} for users who have
+vaapi hardware acceleration capability on their graphics board is via a script. Speed
+up could potentially be 10 to 30 times faster depending on the parameter values you choose
+and the size of your video file. This script is included in the doc subdirectory as
+vaapi\_proxy.sh for users not using an AppImage version and is shown below. You will
+have to tune it to your specific needs for the vaapi\_device name (currently set to
+/dev/dri/renderr128), file type (currently set to h264 and mp4), and proxy size (now is 6).
