The SDK supports NalHrdConformance, RecoveryPointSEI and AUDelimiter for
hevc encoder, so we may allow user to set these coding options like as
what we did for h264_qsv encoder.

These bits are reserved in earlier versions of the H.264 spec, and
some poor hardware decoders require they are zero. Thus, it is useful
to be able to zero these on streams that may have them set. The result
is still a valid H.264 bitstream.

Support single input for guided filter by adding guidance mode.
If the guidance mode is off, single input is required. And
edge-preserving smoothing is conducted. If the mode is on, two
inputs are needed. The second input serves as the guidance. For
this mode, more tasks are supported, such as detail enhancement,
dehazing and so on.

Remove some incorrect (or at least misleading) statements, such as the
formats being ordered by quality, or the first format being the native
one. Neither of those are true for hardware acceleration, which is the
main use of this callback.
HDR10+ metadata is stored in the bit stream for HEVC. The story is
different for VP9 and cannot store the metadata in the bit stream.
HDR10+ should be passed to packet side data an stored in the container
(mkv) for VP9.
This CL is taking HDR10+ from AVFrame side data in libvpxenc and is
passing it to the AVPacket side data.

Decoders like cuviddec ignore and overwrite all the properties set by the generic
code as derived from AVCodecInternal.last_pkt_props. This flag ensures libavcodec
will not store and potentially queue input packets that ultimately will not be used.

Since commit 89ffcd1, the status pts of the output link is set to a
value in the input link time base, not in the output link time base when
EOF is reached. Usually this pst value is larger than the required one
because the output link time base is more greater than the input link
time base. When "-vf vpp_qsv,fps" is used, user has to wait a long time
for the ending of the pipeline because fps filter output a huge number
of frames until the wrong status pts is hit.
The issue can be triggered with the command below (use a clip with 1000
frames in this case):
$> time ffmpeg -hwaccel qsv -c:v hevc_qsv -i input.h265 -vf
"vpp_qsv=w=1920:h=1080,fps=fps=30" -f null -
...

may be wrong.

In order to avoid the above issue, the same time base for input and
ouput links is used in this patch.
