Update for WebM compatibility

[bvibber]

ogv.js 1.5 includes WebM support enabled by default; should update the source checks so WebM audio and video sources get through.

@Brion I've done an update of the dependencies in #28 - do you think WebM support only needs updating the ogv dependency as I've done or needs more refactoring?

[bvibber]

@rigelk I think it needs one more tweak which I temporarily patched out over in MediaWiki land here: https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/TimedMediaHandler/+/master/patches/videojs-ogvjs-webm.patch

That changes the canPlayType method to pass through to the underlying player.

Ah thanks!

I get the error that _OGVPlayer2 is not defined when doing the changes of your patch in src/plugin.js. Any idea what I could be missing?

[bvibber]

Ah woops the patch was against the transpiled output. :) Needs to be slightly tweaked, eg remove the 2 that gets added in the scoping adjustments.

[rigelk]

Ah I wasn't sure if it was due to the scoping, thanks!

Seems to do the trick ; it's now in the PR: https://github.com/hartman/videojs-ogvjs/pull/28/files#diff-a4f485aa834ca5b3c24819fceb39c56fR556
