Thanks. I have put the movies on my nas and know the sub. Is working
MrMC Support Forum
One possible issue I noticed is video stream is a byte stream instead of a bit stream. MP4's are always bit stream formatted. Could be that this is confusing demuxers that expect mp4's to contain bit stream format.Grencola wrote: ↑07 Jul 2019, 20:36so I've tried basically every program I could find to demux these mp4's (and LG DV .ts demos also), but nothing keeps dolby vision attached to the video track, it just becomes hdr10. it's as if, during muxing, dvhe writes the Metadata directly to the specified container (.ts or .mp4) only, so there's no way pull out a video track with any dv. seems the best chance of getting dv with hd-audio in MrMC is to either get DVDFab to make a ts.dolbyvision profile instead of MP4, where we can then just swap out the audio track, or wait for the Matroska team to push an mkv update with dvhe support.
Interesting, so the .ts and .mp4 samples here: https://drive.google.com/folderview?id= ... acOoHuHS9v must be bytestream as well then? They do the exact same thing when demuxed. The only retainable DV Metadata is the second layer 1080p dv track from uhd discs. But there are no public tools to convert it to a binary encoded RPU file to hardcode it directly onto the elementary track using x265's new --dolby-vision-rpu option.

his English isn't the best, but I take it the single layer mp4 dvdfab makes is NOT dolby vision? it just contains some rpu info to flag the logo lol? or did I read this wrong?Below is from Dev Guy,
Single stream is BL+RPU,
Two Stream is Main Stream HDR10 video, Second Stream EL+RPU
And Dolby Vision is in RPU, Both will have Dolby Vision.
Single Stream not have EL for now. It is not Dolby Vision, it some info for HDR10 to 12bit .
Mp4 container not have such mode as in Dolby Demo files for now.
