picture encoding heuristics tweaks — at Version 1

Description (last modified by Antoine Martin)

Based on log samples from #2029, #2022 and others:

  • maybe use x264 ahead of vpx in more cases (changes to "size-efficiency" attribute?): the bandwidth cost of vp8 / vp9 varies more (which hurts bandwidth management) and / or encode faster (currently double that of x264 at similar speed settings)
  • take min-speed and min-quality into account when calculation their corollary
  • ensure we don't choose YUV444P csc step
  • always try to maintain 25fps, drop speed and quality to try to achieve it
  • take scaling attribute into account when using the number of pixels/s

Better unit tests.
