 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.
 https://forum.doom9.org/showpost.php?p=1976413=24

 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.

Comment:

 Assigning to owner of Twitter. Is it possible that our decoder of official
 thd is still partially lossy? Off-by-ones are either on our side on
 Dolby's. We need to know.

 Carl, can you become the 0x0 links? Or should I?
