Dolby Vision now possible through MP4 Mux.

[chros]

Is this only an issue with player-led Dolby Vision? Can the C2 perform TV-led Dolby Vision while still using the x700 to avoid the issues with L1?

those video are TV-led

it's also an issue with LLDV and it's actually a lot worse because not even L2 works with player-led TV.

Your Mutli_pattern_dv_p8 sample looks weird on Plex, but OK on Oppo (take a look at the bottom, clipping, conversion)

yep, I noticed that too. It behaves a bit like the Shield but not as bad.

But Quietvoid found out that the BL luma is messed up in the original spears pattern. It's also encoded with incorrect static metadata.
If we fix the BL luma, no more clipping/conversion error at the bottom on the shield and C2, so I'm not sure this pattern is actually helpful

Thanks, good to know, didn't know it had issues (Spears messed up so many things with that disc, and it's used for benchmarking ).
Then let's try out this one, Seq Dovi 16mps (profile 5), form le labo dejay, it has similar pattern in the beginning:

Off: good thing is that 2022 models has pretty good Hdr10, even in PC mode! What a turnaround...

I tried that pattern the first week I got my Tv and didn't see anything wrong with it.
Regardless of the issue with cmv2.9 hdmi device, I think the 2022 LG oled are amazing TV at least for HDR. I don't watch SDR stuff on it.

This new DV incompatibility with newer TVs might be the final straw for me with Dolby Vision haha. Seems just far too easy for me to just convert all my BDMV folder rip of DV films to HDR10 and call it a day.

Thank you @RESET_999 This is a huge revelation. Anyone know how to contact Dolby lab about this issue, maybe they can update old players to cm4.0?

[RESET_9999]

maybe they can update old players to cm4.0?

I don't think they can do that but I'm sure they can fix the issue via a firmware update on the newer TVs.

Regarding the L1 bug that was recently discovered, does this affect all movies?

Do all movies use L1 information? If not, can I check if a movie contains it?

Does this only affect newer UHD/DV movies?

I'm struggling to find a good way to play FEL movies now...

Thanks ... I've read that but I'm confused especially regarding the Oppo 203. This player was regarded as the best (ie. "reference quality") but nobody has noticed this bug for years? (and no reviewer mentioned this problem when testing, etc?)

well, the bug only affects the newer TV, and quietvoid's pattern is quite recent and without it, it can be hard to spot.
I heard a lot of people with CX/C1 saying that they find the quality much better using the internal TV player. Now it makes more sense than ever.

Also, the DV engine is a black box to the player. So its not oppo,sony's fault

Dolby can do that, it's only a matter of whether they want to.
There's no way for Apple to prepare hardware for 5 years ago iPad to do cmv4.0.
In fact, I think they can let any device that is capable of decoding 2 hevc tracks at same time be able to display FEL through software update.

Does anyone know if there is a better way to hybrid RPU to BL?
I'm trying to extract RPU from profile 5 ICtCp Pirates.of.the.Caribbean.2003 and hybrid that to Bluray BL to get unofficial MEL.
The only problem is RPU in P5 is like 0.5s ahead of the Bluray. But P5 is actually slightly longer than Bluray.
So is there a better way to find out how many RPUs I should exactly duplicate at the begining instead of try again and again? Many thanks.
By the way, there is no DV Bluray for this series right? I couldn't find any on rar*g.

Could someone explain in layman term how this new L1 bug affects the picture quality?I read the last few pages but don't quite get it. I'm using the recently purchased x700 with the lg c9 oled and it sucks if it turns out the x700 is unusable again.
