FFmpeg使用vp9_cuvid解码VP9 4K HDR10视频转HEVC时丢失HDR10信息的问题求助

大家好，我正在尝试编码一个4K VP9 HDR10视频，视频文件名为：(PS5) THE PACIFIC WAR 1943 ｜ Realistic Immersive ULTRA Graphics Gameplay [4K 60FPS HDR] Call of Duty [kgppJX0G--E].webm

我用的FFmpeg命令如下：

ffmpeg \
  -vsync 0 \
  -hwaccel cuda \
  -hwaccel_output_format cuda \
  -c:v vp9_cuvid \
  -crop 276x276x0x0 \
  -i "(PS5) THE PACIFIC WAR 1943 ｜ Realistic Immersive ULTRA Graphics Gameplay [4K 60FPS HDR] Call of Duty [kgppJX0G--E].webm" \
  -c:v hevc_nvenc \
  -preset slow \
  -rc vbr \
  -rc-lookahead 20 \
  -b:v 28M \
  -bufsize 5M \
  -maxrate 28M \
  -g 250 \
  -an \
  -sn \
  output_video.hevc

FFmpeg运行过程看起来正常，但是输出的HEVC视频没有保留HDR10信息（如果换成hevc_cuvid解码的话就不会有这个问题）。同时FFmpeg还抛出了以下错误：

Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scale_0'

[out#0/matroska @ 0x557dd52a7000] Nothing was written into output file, because at least one of its streams received no packets.

有没有大佬能帮我看看这是哪里出问题了？怎么才能让输出的HEVC视频保留HDR10信息，同时解决这些报错呢？
