This is still an issue on 1.23.2.4600 in an Ubuntu Docker container. Even on an 8 core Xeon, I can’t tonemap HDR files to SDR without killing the server for playback to my Appletv 4k. None of my other players have this issue so it’s a double hit. Is there an actual, succinct recommendation to get this to actually work? I see talk about the app grokking the uname or arch wrong or something but no real definitive answers to a fix.
