Below is the testing ffmpeg command for the setting:
./ffmpeg -i input.ts -c:v hevc_videotoolbox -color_primaries bt2020 -colorspace bt2020_ncl -color_trc smpte2084 smpte2048.ts
./ffmpeg -i input.ts -c:v hevc_videotoolbox -color_primaries bt2020 -colorspace bt2020_ncl -color_trc linear linear.ts

Patch looks reasonable to me. Will commit in a few days if no one else
comments.

A while back, a similar patch was rejected for NVENC (from the same author)
on the basis of such functionality not being suitably placed as an encoder
feature.

Looking back at other implementations, eg hevc_vaapi, the same is indeed
allowed, where SEI metadata retention for HDR is present.

To the OP: If the patch for NVENC were refactored in a manner similar to
this, abstracting details such as master display info for HDR (something
that was specifically flagged as not suitable as an encoder feature), it
might pass the patch review and be merged.

Are there specific limitations (as implemented) that block such a feature
in NVENC? Perhaps the initial patch with mastering display controls for HDR
was written that way to circumvent such a limitation.

Regards,

Dennis

I think you are confusing the type of patches here. This does nothing
but extend existing functionality to forward a few more values in
basically an enum that was already being set.
The other patch was about parsing user inputs and generating SEI data,
which should arguably be done in a central place instead of every
encoder individually.

Testing for the new transfer functions when compiling for OSX 10.12 reports
the color settings as "yuv420p(tv, bt2020nc/bt2020/reserved)" in ffprobe.
Is "reserved" (0) the expected default when the transfer function isn't
supported?

mac 10.13 support:
kCVImageBufferTransferFunction_SMPTE_ST_2084_PQ
kCVImageBufferTransferFunction_ITU_R_2100_HLG

OSX 10.14 support:
kCVImageBufferTransferFunction_Linear

For 10.12, the HAVE_* macros should be detected as 0 if correct.

0 is a reserved value in the color specification and should be avoided if
possible.
Would it be possible to fallback on 2 (unknown) when these macros are not
found?

My old mac pro don't support hevc, so I can test it. Please check the
HAVE* is 0

➜  ffmpeg.git git:(videotoolboxenc_v2) ✗ sw_vers -productVersion
10.11.6
➜  ffmpeg.git git:(videotoolboxenc_v2) ✗ grep "HAVE_KCV*" config.h
#define HAVE_KCMVIDEOCODECTYPE_HEVC 1
#define HAVE_KCVPIXELFORMATTYPE_420YPCBCR10BIPLANARVIDEORANGE 0
#define HAVE_KCVIMAGEBUFFERTRANSFERFUNCTION_SMPTE_ST_2084_PQ 0
#define HAVE_KCVIMAGEBUFFERTRANSFERFUNCTION_ITU_R_2100_HLG 0
#define HAVE_KCVIMAGEBUFFERTRANSFERFUNCTION_LINEAR 0

I have submited another patch to fix it, please try whether it's OK.

OSX have defined it as string and no such string map to 2(unknown), so if we 
failed to get the map string, it'll set to NULL and we'll not set the interface. 
Or we should check the result and failed the init to avoid it.

but it's not related to the patch, without it, you should get the same result.
