Replying to [comment:53 Balling]:
> You understand that pirates on rarbg use ffmpeg? The metadata is correct
for both the original bit perfect WEBDL or Blu-ray and downconverts. Dolby
Vision content obviously could not be downconverted yet.
> So there should be a perfectly working script out there that uses that
json ffprobe data, for example. Github is the place for it, or github
gists. I will try to search through it /sigh
I have searched as you suggested on RARBG for their 4K encodes and no
matter it was WEB or Bluray encodings (on every group), the mediainfo
shows that they were using x265 library on Windows for encoding, no
mention of ffmpeg/lavf encoder. They either aren't using ffmpeg at all or
just avoid it for 4K HDR releases because of missing support.
