[libcamera-devel] [RFC v2] [PATCH 0/1] qcam: Render YUV formats frame by OpenGL shader

[Show Liu]

This patch is to render the YUV(NV formats family) frame by OpenGL shader.
I rework viewfinder class and give viewfinder handle abstract class as interface 
and make it able to handle viewfinder and viewfinderGL both.

I tested on rockpi4b with kernel 5.7rc4+imx219 camera module.
