xHE-AAC relies on the same postfilter mechanism
that Opus uses to improve clarity (albeit with a steeper

The code to apply it is identical, it's still just a
simple IIR low-pass filter. This commit makes it possible
to use alternative constants.

Adding 10-bit encoding support for HEVC if the input is 8-bit. In
case of 8-bit input content, NVENC performs an internal CUDA 8 to

AV1 supports encoding 8-bit content as 10-bit.
