[Wrong diagnostic, please ignore] PMS seems unable to transcode SOME Display P3 mastered videos

Plex Media Server
1

Server Version#: 1.40.4.8679
Player Version#: 10.18.0.968 (also tested on a Samsung TV which I don’t know the version)

Every HDR video with “Mastering display color primaries : Display P3” that needs to be transcoded for my phone or friend’s samsung TV (generally because of EAC3) will just load endlessly.

When selecting a compatible audio track, like AAC, video will play fine (direct play)
Other DV/HDR videos with BT.2020 mastering will play flawlessly with transcoding.

edit : I was wrong, some DP3 mastered are transocding without any issue. Now I can’t find why some other won’t…

I was totally wrong, this isn’t an issue with DP3 but with subtitles, will create another post about this.
