[Mesa-dev] Fwd: [PATCH] st/vdpau: use bicubic filter for scaling

[Nayan Deshmukh]

Hi Christian,

I will send a new patch in which the calculation is done before using the
constant buffer.

Also, Grigori suggested me to use gather4 instead of sampler to get the
textures. I tried
using it but I don't see any code from where I can take inspiration to use
that.

Regards,
Nayan.
