 ogv.js will try to auto-detect the path to its resources based on the script element that loads ogv.js or ogv-support.js. If you load ogv.js through another bundler (such as browserify or MediaWiki's ResourceLoader) you may need to override this manually before instantiating players:
 
 ```
-  // Path to ogv-demuxer-ogg.js, ogv-worker-audio.js, dynamicaudio.swf etc
