Change subject: Increase quality of Ogg Theora video transcodes
......................................................................
Increase quality of Ogg Theora video transcodes
"Shifts" the current video bitrates on Ogg Theora video
transcodes to twice the birate used for WebM/VP8 and H.264,
hugely increasing picture quality in scenes with moderate
to high amounts of motion.
Adds a 240p transcode for Ogg Theora with the same bitrate
as the old 360p transcode, so there's still a middle-bandwidth
step above 160p15, that will often look better than the old
360p due to having less artifacting.
Future adaptive streaming with ogv.js will be able to select
these based on available bandwidth (and for WebM using native
Media Source Extensions in Firefox/Chrome).
Bug: T106995
