There appears to be a rounding error in jheora that causes areas of the video that contain faint noise to become increasingly distorted, until a keyframe comes along and clears it and it starts over again. I reported this bug back in 2006 to Fluendo, see: https://code.fluendo.com/flumotion/trac/ticket/370 I've placed a test page on my new site with the test file here: http://webcam.firestorm.cx/test
TimedMediaHandler was deployed at the beginning of November 2012, see https://www.mediawiki.org/wiki/TimedMediaHandler and http://blog.wikimedia.org/2012/11/08/introducing-wikipedias-new-html5-video-player/ for more information. It is based on HTML5 and supports closed captions, timed text, WebM, etc. This bug report was reported about "Cortado". With TimedMediaHandler being in place, Cortado is now ONLY used as a fallback for web browsers that do not support any of the video codecs we offer but have Java installed. This currently is Apple Safari without XiphQt installed, or Microsoft Internet Explorer with Java applet installed. Please add a comment here in case that you still face the problem described (now with Cortado inside of TimedMediaHandler) if using one of the browsers mentioned above. In that case, this report should be moved to product="MediaWiki extensions" and component="TimedMediaHandler" in this bug tracker. Issues that also happen with Cortado without TimedMediaHandler should be reported to https://trac.xiph.org/ instead.
Fixed a few years ago: https://trac.xiph.org/ticket/1559
