Brion VIBBER has uploaded a new change for review. (

Change subject: Final adjust to Ogg Theora transcode settings
......................................................................
Final adjust to Ogg Theora transcode settings
Apply some final tweaks to Ogg Theora transcode settings:
* use --soft-target on ffmpeg2theora
* use a bandwidth target instead of quality target on HD targets
* include 1440p and 2160p defs for comparison testing
* don't force super-low frame rate on 15fps
(Note that Theora output is not in use in production anymore, and
will probably be removed later entirely.)
