Couple of things to do here probably:

  • add the .opus extension & "audio/ogg; codecs=opus" mime type to our lists
  • make sure that .opus files that get uploaded keep their .opus extensions and don't get renamed as .ogg or something
  • support in TimedMediaHandler to play them in supporting browsers (how to check?)
  • support in TimedMediaHandler to transcode .opus to other format(s) for non-supporting browsers

And of course.... deploy TimedMediaHandler (bug 27699).

As of firefox 15:

dummyvid.canPlayType( 'audio/ogg;codecs=opus' );
"probably"

Yes, once we get 27699 out of the way, we can enable opus, mp3 and h.264 transcodes and playback relatively easily, since the mechanics for source stream switching and client feature support detection are already supported for the existing set of codecs that we support.

Since TMH is deployed, is Opus transcode and playback possible?

Opus can now be forced into the OGG container, but the Wiki servers have problems detecting the codec. Also playback is limited in some browsers (chrome at least).

Note that Chrome as of version 38 plays this opus-in-ogg file natively just fine. Yay upgrades over time!

I also have Opus support in ogv.js, so once that lands we should have working playback in Safari 6.1+ and IE 10+ as well, with or without Vorbis transcodes.

You can upload the file here
https://commonsarchive.wmflabs.org

And add the template:
{{Commons Archive|My_raw_file.opus}}

in your media in commons, look this example with NEF file:

You can upload the file here ...

Which completely mitigates the advantages of opus. commonsarchive should only be used to archive raw data like hdr for images (or zip archives are allowed as well,I think)
But you can already upload raw wave files directly to commons so commonsarchive is not useful for audio files.

Ok, so these days everything works with Opus-in-Ogg uploaded as .ogg or .oga extension, but we don't accept the .opus extension. Should be an easy fix.

Ok this is merged. :D Should go out next week or the week after (I'm a little vague on deployment schedules this month, there's US Thanksgiving holiday later in the month)
