What options are there for playing WebM video files on Mac OS X other than VLC? A plugin to Quicktime Player would be perfect.

Perian, a QuickTime plugin should support WebM since version 1.2.2 according to their website.

I have Perian 1.2.3 and Quicktime Player 10.1 on OS X Lion fails to open .webm files with an error message. – Daniel Beck Feb 1 '12 at 13:18
Could be, I've never tried it. It may be that WebM is a mess of formats and containers as other formats before ir and Perian supports some but not all of them. – lupincho Feb 1 '12 at 13:25
Judging from the Wikipedia article, it seems rather well defined. Still, +1 because someone apparently got it working, otherwise it wouldn't be in Perian. – Daniel Beck Feb 1 '12 at 13:30
Works for me too, with Perian 1.2.3. Added evidence to the answer ;) @dan – slhck Feb 1 '12 at 13:45
The problem may be QuickTime X in Lion. Possible Link – afrazier Feb 1 '12 at 16:20

Not really much to choose from on OS X. While Perian is indeed VP8-capable, to play modern VP9 WebM's you may try minimalistic mpv player.

On the second thought, you may not need a dedicated video player for any WebM at all, just open the file with any recent version of Firefox, Chrome, Opera or Safari and watch the video.
