This needs an exact testcase (URL, browser) if this is still valid (plus a permanent link to WP:VP would have been good in case there *was* a testcase...).

Manish: Any idea? With TimedMediaHandler having been deployed I'm tempted to close this as RESOLVED WORKSFORME.

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.

Unfortunately closing this report as no further information has been provided.

Manish: Please feel free to reopen this report if you can provide the information asked for and if this still happens. Thanks!

(Testcase missing as http://en.wikipedia.org/Grindcore only provides one piece of sound.)
