1536174 - Add mechanism for recording significant composites for creating recordings of things like pageload

Status: RESOLVED FIXED

(Core :: Graphics: Layers, enhancement)

Description

[Bas Schouten (:bas.schouten)]

Since screen capture software run locally can interfere significantly with pageload and browser operation. It would be good to have a way to efficiently be able to capture visual page load progress.

Bas: this doesn't look very arch specific, but in a meeting today you suggested it needed additional work to function on Android. Can you confirm, and if that's so, open a follow-up and sketch out that work? Thanks!

Code needs to be added to grab a copy of the framebuffer in LayerManagerComposite/CompositorOGL. Brennie or Markus would probably know exactly what needs to be done. It's the bit in gfx/layers/mlgpu/LayerManagerMLGPU.cpp that's arch-specific.
