Nope, I've tested LG C9 only.
It also works well on my C2 but the 2018 or older TV are more picky in regard of DV MP4.

if anyone with old LG TVs could test the latest beta script, workflows 7-2, that would be great. You have to update the mp4muxer.exe by the one from here: https://github.com/bbeny123/mp4muxer

Sorry to reply to you directly but would you able to confirm my question on profile 8 hybrids? I can't find a diffinitive answer and it seems like EVERYONE is encoding with profile 8 hybrid formats now. I'm not seeing ANY native profile 5 formats any longer :-/. Do you see this as an issue? This is in reference to P5 streams combined with hdr10/+ streams, not hdr10 blurays that are combined with a p5 stream.

I tested DV-Profile 8.1 with my Oppo, it played only HDR. Built-in Player in my Sony XR 90 plays Dolby. That is a pity, because ver 1.3 is really fast. Only ver 1.0 works reliable for my Oppo.

making p8 hybrid is not an issue as long as you make sure the P5 and HDR10 encode are the same brightness/master. I have a huge excel sheet about it in my signature.
Most of the p2p or scene groups make hybrid without checking any of this and it is a problem especially if they are not going to release the profile 5 source which seems to happen more frequently lately.
While most of the time, the P5 and HDR10 encode are from the same source/master, it doesn't mean it will always be the same, and making hybrid releases blindly is wrong.
And sometimes studios decide to deliver different trim pass even though it's from the same master.

two examples I came across recently:
Black Widow profile 5 iMAX is much brighter than the HDR10 IMAX web-dl: https://slow.pics/c/zzHW5Qhv
And recently Hot Pursuit (which FLUX only released hybrid P8): https://slow.pics/c/37t2bB4J

Thanks. This is kind of what I was afraid of. There's really no way (for a normal person like myself) to tell whether a "hybrid" encode was done properly. I'm basically seeing ONLY hybrid files for all new streaming shows being encoded. These encoders are not posting the original profile 5 sources which is absolutely infuriating. I rather just grab P5 versions so that I know that it has the correct brightness. Why in the world are people not doing this? What changed? Is there any possible way to like "reverse engineer" these files to split back out the p5 stream? or is that impossible?

My fixes were focused on DV-Profile 7 (dual track), but it is possible that version 1.3.2 will also work with the Oppo.

1.3.2-alpha1: https://github.com/bbeny123/mp4muxer/re ... 3.2-alpha1

If 1.3.2-alpha1 still does not work, you can also try 1.3.2-alpha2: https://github.com/bbeny123/mp4muxer/re ... 3.2-alpha2

I stopped grabbing p8 hybrids earlier this year when I learned all of this. There is really only one uploader that I trust.

Is there any way that you could share which uploader you trust? Not sure of the rules here or if you can even send private messages. Feel free to decline if I am crossing a line.

But yea. I just don't understand it.....uploaders who used to upload source P5 materials just randomly all switched to uploading P8 files. I have no idea what happened. I legit cannot find any P5 files of recent streamed shows. They're literally all P8 lol. If they know that P8 files are bad form....then why do they keep doing it?

I suggest this is better to be taken offline into private discussion. My suggestion is just consider paying to watch on your favourite streaming platform, if the possibility of poor DV metadata bothers you this much from said "other" sources. As for why the prevalence of profile 8 DV hybrids now over p5/p8 split before: compatibility and saving time/bandwidth. Cheers.

Alpha 2 triggers Dolby on my Oppo, Alpha 1 fails. MP4 in alpha 1 und 2 is hev1, in ver 1.0 they are dvhe (nevertheless triggering Dolby)

"Original file" meaning the RPU injected hevc-file? The Original from the UHD is without Dolby. If you provide a download link via PM I could upload.

I dont't need it anymore, I managed to find some other video with DV profile 8.1 :)

Could you please check out version 1.3.2-alpha3? It should work with Oppo (and older LG TVs) and have the codec set correctly to 'dvhe'.
