This is a fast way to make a video loop forever. It supports optional prefixes that play before the loop.
Standard Loop
To use the standard loop functionality, specify the path to the files excluding the extension with the v variable. Example:
https://iwalton.com/videoloop/?v=clock would look for
https://iwalton.com/videoloop/clock.webm and
https://iwalton.com/videoloop/clock.mp4.
Multi-part Loops
To use the prefix function, specify the first part of the _loop and _pre files. Example: https://iwalton.com/videoloop/?p=clock would look for https://iwalton.com/videoloop/clock_pre.webm, https://iwalton.com/videoloop/clock_pre.mp4, http://iwalton.no-ip.org/videoloop/clock_loop.webm, and http://iwalton.no-ip.org/videoloop/clock_loop.mp4.
