Dolby Vision is implemented in FFmpeg+mpv (IPTPQc2 colorspace plus MMR reshaping, output to PQ surface works since yesterday, reference with LG C9, that is reference v4 Dolby Vision implementation from Dolby), no support for (F)EL or dynamic metadata. Test patterns for Dyn. metadata are available. Even iPhones' HLG styled Dolby Vision works (MMR), while it does not work on Apple TV 4K, ha. Apple added support, but RPU reshaping somehows does not happen as someone with a root verified.
