MKV Dolby Vision Demux

Post by agressiv » Sat Nov 07, 2020 8:08 pm

Two questions:

1) Is there a way of demuxing the EL/RPU from an MakeMKV-created Dolby Vision MKV?
2) Assuming you can do this, has anyone tried doing an encode of the BL and then tacking on the EL that you've demuxed? I get lots of errors when I remux this:
AV sync issue in stream 0 at 0:00:04.379 : secondary stream video frame timecode differs by +125.122ms
AV sync issue in stream 0 at 0:00:04.421 : secondary stream video frame timecode differs by +291.958ms
AV sync issue in stream 0 at 0:00:04.421 : secondary stream video frame timecode differs by +125.125ms

AV sync issue in stream 0 at 0:00:04.462 : secondary stream video frame timecode differs by +166.827ms
AV sync issue in stream 0 at 0:00:04.671 : secondary stream video frame timecode differs by -83.425ms
My goal is to have encoded files with x265 while preserving Dolby Vision - if possible. I could attempt to encode into profile 8.1 with x265, but I want it to be playable on Plex on an nVidia Shield 2019.
