The Constant Quality (CQ) range for the AV1 codec is actually 0 to
63, contrary to what is stated in the header and documentation.

When Split frame encoding is enabled, each input frame is partitioned into
horizontal strips which are encoded independently and simultaneously by
separate NVENCs, usually resulting in increased encoding speed compared to
single NVENC encoding.

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
10-bit conversion of the input prior to encoding. Currently, only
AV1 supports encoding 8-bit content as 10-bit.

Hi Roman and Timo,
Timo is right. As a general rule, hybrid video coding standards allow encoders
to take advantage of encoding
a 8-bit input as 10-bit due to the interpolation filters (inter and intra) and
transform coding at 10-bit depth.
This can generate a better prediction and reduced bandi

The supported YUV pixel formats were separated between planar
and semiplanar. This approach reduces the number of CUDA kernels
for all pixel formats.
This patch:
1. Adds support for YUV 4:2:2 planar and semi-planar formats:
yuv422p, yuv422p10, n

Add support for uploading additional pixel formats to NVIDIA GPUs:
- Planar formats (yuv420p10, yuv422p, yuv422p10, yuv444p10)
- Semiplanar formats (nv16, p210, p216)

Remove redundant display_sei_sent flag for 3D reference display info
handling in MV-HEVC encoding. The display SEI must be sent for every
frame in the multi-view sequence.
