QuickLook webm previews in Mountain Lion about perian HOT 4 OPEN

QuickLook on 10.7 used QTKit, and thus QuickTime, for generating thumbnails. Later OS X versions use AVFoundation, which does not call QuickTime, and thus doesn't call Perian.

Sorry.

I had QuickLook previews of webm files on Lion (10.7.5) with v1.3.2 but after upgrading to 10.8.5 i no longer have previews of webm files. They play fine in Quicktime and VLC though. Is Perian supposed to provide additional QuickLook previews?

hmm, i see. do you know of a way to generate thumbnails thru AVFoundation?

The API to do so is private.

The best alternative would be to create a new QuickLook plug-in, with perhaps a way to transcode video and audio into a format that AVFoundation can read. To my knowledge, VP8 and VP9 aren’t supported.
