10- and 12-bit DNxHR use the same DC coefficient decoding process and
VLC table, just with a different shift value. From SMPTE 2019-1:2016,
8.2.4 DC Coefficient Decoding:

"For 8-bit video sampling, the maximum value of η=11 and for
10-/12-bit video sampling, the maximum value of η=13."

A sample file will be uploaded to show that with this patch, things
decode correctly:

In order to avoid possible clipping at the very
beginning. Especially apparent when "alternative"
boundary mode is used.

Adopted from original commit by committer.

Doxygen gets confused by this.

Fixes ticket #5484.

The interface has been stable for some time now.

The Doxygen command is generated from the list of installed headers,
which may change per configuration (e.g. `--enable-gpl` results in
libpostproc to be built and installed).

HDCD is only encoded in s16@44100Hz. Scan the chain of AVFilterLinks
for any resampling or format conversion/truncation that might cause
problems for the filter and issue warnings.

Issue #5727: gain adjustment should only be applied if matching
gain value from a valid packet in both channels. The existing functions process
each channel separately, so it was not possible.

* New versions of hdcd_process(), hdcd_scan(), hdcd_integrate() named
  hdcd_*_stereo() that process both channels together.
* target_gain applied will be the last matching target_gain.
* The old single channel functions remain as an option. They can be
  used by: -af hdcd=process_stereo=0.
