[vlc-devel] [PATCH 5/6] direct3d11: bring patch the 128 pixels padding required by the DXVA HEVC decoder

[Steve Lhomme]

Since we don't know in advance what alignment the decoder will need we use the
maximum.

This is needed in light of the previous bug fixed where the decoder accepts
texture with the wrong alignment but uses them as if the alignment was correct.
So we always need to make sure the alignment is correct.
