does CoreElec do DV?

Sadly, no. At least not the version I installed some time ago. I gave up on the DV playback. When I read about this USB thing to make dualboot possible, I gave it a go. CoreElec has proven stable and responsive.

I see some groups are making DV hybrids where the web-dl and UHD BluRay are not matching on Display Aspect Ratio.

Example with Onward
WEB-DL: 2.40:1
UHD BluRay: 16:9
Hybrid result: 16:9

In the awesome dolby vision tool from RESET_9999 it states "both videos must have the same aspect ratio otherwise DV wont be accurate".
Is there a solution to change the aspect ratio? or is it just to change the L5 active area?
Sorry if i sound a bit confused :D

UHD BD are only 16:9 because they encode the black bars in the video so you just have to set a proper L5 active area just like I did in the video.

I meant when both videos has a different letterbox. EG, IMAX vs non-imax video. see this post: viewtopic.php?p=114950#p114950

instead of answering always the same question over and over, I made an excel sheet resuming pretty much everything that works or not.
If you want to add anything, let me know.

FYI: the tsMuxer corruption bug seems to be fixed in the latest nightly (f4fa419 / 2022-02-22-18-30-10).

I've done a couple of full movie remuxes with it and they both passed the test of being fully decoded by ffmpeg with no errors.

I can confirm for LG G1 at least the built in player falls back to HDR10 on profile 7.

The situation right now seems to be that there is no good solution to play all DV profiles (or at least 5 and 8) with lossless audio, except from original bluray discs. Since all the players that can do lossless audio have other issues.

Or are there others that will do the job?
