|Summary||0001431: Investigate opengl canvas for rendering preview/player.|
|Tags||No tags attached.|
|Estimated work required||Unknown|
Basically functional in opengl branch.
Works on OSX, not Windows; seems to be because glTexImage2D has limitations on the size (either too big or not a power of 2).
Would be interesting to make GLView take a PlayerVideo (rather than an Image) and do the scaling and compositing using GL.
Is there a chance we get a better player performance for many cores/high resolutions in 2.14? It seems there is a serious bottleneck in the current implementation. I rarely work on high res displays, but it seems there is something weird happening.
I somehow suspect the final display writing as the bottleneck (as it appears the issue is somehow correlated to higher res displays), but maybe I am on a completely wrong track here. Maybe there is something going on with a higher number of threads/cores.
