Replying to [comment:6 Balling]:
> Then you can check some older encodes, those were not even decoding at
all in Plex, it did not like the bitstream, even though it was just a
couple of flags.
I got the confirmation that some commit fixed Oppo stereo thd playback
too. Not only Plex.

I also got Dolby Reference player and there artefacts are much less
profound, at least in 32 bit float. But I still think there is a bug, AT
LEAST compression algorithm code is horrible. BUT!!
https://0x0.st/oJBa.mlp is not apparently lossless, it has some small
amount of byte differences (!). So there is also a bug in Dolby Media
Encoder or there is an additional off-by-one bug in our decoder.
