#2052 assigned enhancement

downscaling server side - not just for video

Reported by: Antoine Martin Owned by: Antoine Martin
Priority: major Milestone: 4.0
Component: encodings Version: 2.4.x
Keywords: Cc:


When the client is using a desktop-scaling value lower than 1.0, we end up sending pixels that aren't all used client-side since we end up downscaling the picture to display it. (the render target is smaller than the picture the client receives)

It would be better if the client could tell the server about the scaling factor it is using then the server can:

  • choose this same factor (or more) for video scaling - easy
  • downscale picture data before compression: new capability flag, new client option, image down scaling pre-compression
