I can’t tell from the spec - if I pass in an 8-bit luminance texture, and request this as the internal format, will the driver compress it for me?
And would it do it quickly, i.e. hardware, or slowly as it transfers?
I suppose I’d also like to use it as a PBO and render to it, if that’s possible? The goal is to apply some mild compression to 4:2:0 video textures.
