When mDCv support was added, there was a typo in both variable names
and also the MKTAG itself, incorrectly listing it as mDVc. The tag name
stands for Mastering Display Color Volume so mDCv is correct.
Typo originally introduced in 78949041417caaef0c82b2b23d7defdd88aa2378.

In intra-only mode, frameIntervalP is 0, which means the frame
data array is smaller than the number of surfaces.
Together with using the wrong size on deallocation of the
frame_data_array, this lead to a crash.

There is no bsf for other codecs to modify crop info except H.265.
For H.265, the assumption that FFALIGN(width, 16)xFFALIGN(height, 16)
is the video resolution can be wrong, since the encoder can use CTU
larger than 16x16. In that case, use FFALIGN(width, 16) - width
as crop_right is incorrect. So disable the workaround for H.265 now.

Fields under the segmentation switch are never reset on a new frame, and
retain the value from the previous frame. This bugs out a bunch of
hwaccel drivers when segmentation is disabled but update_map isn't
reset because they don't ignore values behind switches. This commit also
resets the temporal field, though it may not be required.
We also do this for vp8 [1] so this commit is just mirroring the vp8
logic.
This fixes an issue with certain samples [2] that causes blocky
artifacts with vaapi, d3d11va and cuda (and possibly others).
Mesa worked around [3] this by ignoring these fields if
segmentation.enabled is 0, but d3d11va still displays blocky artifacts.

Since the SBR noise application optimisations are currently restricted
to hardware with 128-bit vectors, and use a quadruple multipler, they
can load up to 16 32-bit elements. But the "loads" are of 2 segments,
or 16 pairs of single precision float.
Thus we need to expand the dupiclated section of the noise table from
2x8 to 2x16 to avoid overflows.

This loop correctly assumes that VLMAX=16 (4x128-bit vectors
with 32-bit elements) and 32 >= pred_order > 16. We need to alternate
between VL=16 and VL=t2=pred_order-16 elements to add up to pred_order.
The current code requests AVL=a2=pred_order elements. In QEMU and on
thte K230 hardware, this sets VL=16 as we need. But the specification
merely guarantees that we get: ceil(AVL / 2) <= VL <= VLMAX. For
instance, if pred_order equals 27, we could end up with VL=14 or VL=15
instead of VL=16. So instead, request literally VLMAX=16.
