It's destructive in the fact that it completely removes the HDR10+ data, and that's not reversible.

Well there is always a trade-off and as long as we have the original backup that shouldn't be an issue. But in the end, like you mentioned that an On/Off switch approach would be much better. Cant wait to test it myself when its ready
The 2019 Shield has no issues playing back FEL and MEL content. Whether or not it's doing it properly is a whole another discussion.
I can play both FEL and MEL on the Shield too. No way for me to know if the Shield actually decodes the full 12 bit, though. But it doesn't even matter since the colors with both profile 7 and 8 are not accurate. Both get ugly red artifacts or color shift. Only profile 5 seems to be decoded properly.
Are these libraries still needed? I forgot to save them and the link is already dead.
Why do you need to go through so much trouble for playback on the oppo clone? Just play it off your folder backup, no?PapitaHD wrote: ↑Tue Oct 13, 2020 8:01 pmAre these libraries still needed? I forgot to save them and the link is already dead.
I'm just asking because for some reason I've encountered 4 movies (War of the Worlds, Terminator Genisys, Terminator Dark Fate, Valerian) in a row that were unplayable on LG C8 and M9702 after converted to MEL. I tried to mux them with tsMuxeR and mp4muxer too but they were all lagging unwatchably on C8 and gave black screen on M9702. I used the latest version of yusesope's tool and it finished with 100% every time.
Has anyone had success with either of these movies?
I'm trying to make remuxes for my friend who has a Philips TV and so far if a MEL conversion played fine on my devices then it worked on his Philips as well.shawnc22 wrote: ↑Tue Oct 13, 2020 8:16 pmWhy do you need to go through so much trouble for playback on the oppo clone?

HDR video recording with Dolby Vision up to 30 fps
Last Saturday I was working on just that. I hope to be able to finish next weekend and above all I hope it will work !quietvoid wrote: ↑Sun Oct 11, 2020 1:49 pmMaybe a good starting point is to just accept a MKV (in addition to raw that exists already) and be able to output the raw converted HEVC file. That on its own would save a lot of time (demuxing MKV, demuxing BL/EL, converting/remuxing 8.1), and might be simpler to do.
Afterwards, the only step left would be to pass this file through MakeMKV, and it can be reused in the original MKV, simply replacing the video (I'm not sure if mkvtoolnix would keep the headers intact if the video changes to a raw file?).
That way you don't have to handle audio, subtitle, etc.
I can only thank you both for your time.
Great news.
So in the end it was HDR10 + ...
No, they are no longer needed.PapitaHD wrote: ↑Tue Oct 13, 2020 8:01 pmAre these libraries still needed? I forgot to save them and the link is already dead.

The zidoo Z9x also accepts the profile 8.1 procedure. I only tested in mkv. But it works fine in this 8.06 profile.yusesope wrote: ↑Wed Oct 14, 2020 12:48 pm

I took a quick look at a few comparisons: the Firestick performs really well. The Shield still needs to improve (but if the Stick succeeds I don't see why the Shield shouldn't do it too).
It also seems that my FEL -> MEL and UHD-> profile 8.1 algorithms work fine.
You experts, do you consider them correct? Do you have any ideas/comments on this?
Thank you!
Code: Select all
Extract the base layer and the enhancement layer
ffmpeg -i path\to\the\file.m2ts -ss 0 -t 120 -map 0:0 -c copy path\to\BL.hevc
ffmpeg -i path\to\the\file.m2ts -ss 0 -t 120 -map 0:1 -c copy path\to\EL.hevc
Using my tool, double click on the MUX_AND_CONVERT_TO_PROFILE_81.bat file and follow the instructions on the screen.
You will get a BL_EL_RPU.hevc file.
Actually, the file does not contain EL (it's just BL+RPU).
BL_EL_RPU is just the filename !!!
Let's put it this way, you are too lazy to use the command line and I am too lazy to add lines of code for the purpose of renaming a file
Simply, create an ISO using BL_EL_RPU and TsMuxeR.
Open the ISO with MakeMKV

Hi ragico, did you do any comparison of the colours in DV with the Ugoos AM6 Plus? Is it accurate like the Firestick 4K or does it also have any colour issues like the Shield?
