So is there a a way to create a single stream DV file from UHD blu ray?
Thanks.
Not available to mere mortals. (There may be some high-end proprietary Dolby mastering software that allows for this - but there's nothing available to general Kodi users)
HOWEVER - https://mrmc.tv/forum/viewtopic.php?f=15...1&start=40 seems to suggest that https://github.com/DolbyLaboratories/dlb...master/bin may allow you to do something clever...
https://www.reddit.com/r/Piracy/comments...x/e75t9oa/ was the source (the --progress seems to be a red herring and should be omitted)
There is some discussion in the reddit though as this looks to be a remux not a profile change - so it may not be doing what people think it is. (i.e. not changing a dual stream to a single stream and instead just muxing the base and enhancement dual stream layers into an MP4)
https://www.dolby.com/us/en/technologies...levels.pdf has more information.
There are LG demo transport streams in different DV flavours in the wild.
The first one has dvhe.05.09 - which means Profile 05 (single base layer 10-bit HEVC)

This stream which is dvhe.04.06 - which means Profile 04 (10-bit HEVC base layer with 1/4 resolution 10-bit HEVC 4.1 enhancement layer) which I believe is a dual-stream?
