How feasible would it be to add shader support? I realise you can't currently use the GPU for video decoding, but can you apply a shader to the image being displayed after it's decoded?
I'm thinking for 3D SBS (side-by-side) support, for use with a labo-type VR headset. Maybe a shader similar to this one which lets you play Virtual Boy games in retroarch in 3D. It looks like each half of the SBS image (which currently fill each half of the screen) would need to be scaled down and warped slightly for curvature, and the two images would need to be positioned the right distance apart.
