Change 238819 had a related patch set uploaded (by Paladox):
Switch on vp9 transcodes by default
Change 238819 abandoned by Brion VIBBER:
Switch on vp9 transcodes by default
Reason:
Not ready to deploy VP9 transcodes. Note Edge's VP9 support mentioned in an old comment is still MSE-only and doesn't work with current TimedMediaHandler's use of <video> element.
VP9 adoption is pretty good these days, and ogv.js includes shim support for Safari, IE, and Edge that's only slightly slower than its VP8 playback and can be optimized a bit further. Should be safe to switch these in soon.
Mainly need additional capacity for encoding in production -- T188075.
