Support For Ogg Vorbis+Theora

[Jason Self]

It appears that recordings added are converted to WebM (Vorbis + VP8 inside the modified Matroska container.) Can you please add support to instead encode into Ogg Vorbis + Theora? Every browser that has built-in support for WebM also has support for Ogg Vorbis + Theora but the reverse is not true, giving Ogg Vorbis + Theora greater browser compatibility.

Add to this that the Java Cortado applet [0] can be used as a fallback method means that browsers as far back as Netscape 4 can play these files.

This would allow many of us to publish a big backlog without much work as well.

And, yes, Theora + Cortado works in Internet Explorer, which is a requirement for a Norwegian government agency that might want to use GMG to publish some conference recordings. :-)

In the future (and maybe already) some people will support WebM though, and not the cortado/or theora option. At that point we might need multiple-format support for GMG (the out-of-tree h264-plugins may already do that work).

This could certainly be a good feature to add. Multi-format support might be a good idea so that it could be added to existing instances without having to reprocess existing media. Related to this would be reprocessing: #420.

Hi Jason/Velmont,

I'm just triaging this ticket. Given that it's been a few years since this request, I just wanted to check whether the situation is the same and that this would still be a valuable addition. Any thoughts?

Cheers,
Ben

In the interests of both keeping the core lean and future-focussed, perhaps the Cortado applet should go in a plugin, but the Theora/Vorbis could be a "output formats list" configuration option in both the audio and video plugins?

Marking as medium-sized as will require quite a bit of work on existing audio/video media types I think.

Just a +1 based on the comments above. All of my users (for reasons I won't go into here) use IE, often locked down with only default codecs. I wish I could use MediaGoblin, but until it somehow supports Internet Explorer out of the box, I can't :-(
