Recommended ways to get GPU acceleration + ffdshow filtering?

[Chainmax]

I plan to buy an ultraportable laptop soon, to be used mainly as a media playback machine/HTPC. Now, these kinds of laptops have relatively weak processors and would not be able to handle 1080p playback with added ffdshow postprocessing. What alternatives would I have in order to have GPU-accelerated playback AND ffdshow postprocessing (like its deband, lanczos resize, noise and deblocking)?

use CoreAVC if you can.

Yes, CoreAVC which is using CUDA interface (nvidia only) is the only way to get hardware acceleration AND postprocessing. You won't get postprocessing with dxva because of the way it works...

btw lanczos resize is available if you use madVR.

I'm usng CoreAVC > ffdshow > madVR, best combination so far. ;)
