There are two group of three_Spline params. Fix the struct
definition and usecases inside libavcodec, libavfilter and ffprobe.

Only patch 1/6 needs to go with major version bump.
Zhao Zhili (6):
libavutil/hdr_dynamic_vivid_metadata: fix
AVHDRVividColorToneMappingParams
libavcodec/dynamic_hdr_vivid: fix start code check
avcodec/dynamic_hdr_vivid: fix base_param_Delta
From: Zhao Zhili
The base_enable_flag is parallel to three_Spline_enable_flag. The
typesetting of the specification is very misleading.

Don't print tone_mapping_param_num if tone_mapping_mode_flag is
disabled.

It conflicts the comments. The operation based on Delta_enable_mode
can be applied by user during tone mapping.

We parse the fallback cHRM on decode and correctly determine that we
have BT.709 primaries, but unknown TRC. This causes us to write cICP
where we shouldn't. Primaries without transfer can be handled entirely
by cHRM, so we should only write cICP if we actually know the transfer
function.
The first patch fixes a FATE issue with cICP and iCCP.
The second patch was discussed on IRC. I got a LGTM from Kasper, but sending to
ML here and applying in a few days if there's no objections.
A few things discussed:
1) There's no need to expose the gamma table as another function as it's

Patents? Which patents? Which country does this apply?
The whole FFmpeg is concerned probably with thousands of patents...
I don't see here the gain.

You do not need this; the channel layout of a freshly allocated stream

Because sharing code between demuxer and decoder is extremely annoying,
because somebody decided the libraries must be separate even though all
