This greatly improves the result when decoding typical (ST.2084) HDR content, since the job of tone mapping gets significantly easier when you're only mapping from 1000 to 250, rather than 10000 to 250. The difference is so drastic that we can now even reasonably use `hdr-tone-mapping=linear` and get a very perceptually uniform result that is only slightly darker than normal. (To compensate for the extra dynamic range) Due to weird implementation details, this only seems to be present on keyframes (or something like that), so we have to cache the last seen value for the frames in between. Also, in some files the metadata is just completely broken / nonsensical, so I decided to apply a simple heuristic to detect completely broken metadata. |
