#178 closed enhancement (fixed)

vpx/x264: offer the user the choice of sacrificing picture quality or fps - sometimes we can't do both

Description (last modified by Antoine Martin)

Our heuristics sit somewhere in the middle at present, but some users may prefer lower fps with near pixel-perfect quality, or maybe just high fps with lower quality.

This would require:

  • --switchname=0...100
  • something in the UI to change at runtime
  • said value in the server used to weigh on the heuristics

Also, it seems that we should be less aggressive with colourspace conversion sub-sampling as this is more noticeable with applications like terminals..
