As a general thought, did you already have Dolby Vision working on your equipment? Meaning, are the firmwares (AVR?) up-to-date and - if applicable - is DV enabled in every device settings?

Yeah sure just noticing this issue with some MKVs.

Hello. Does anyone know why the file on left did not trigger DV on LG B1 despite being Profile 8? Only HDR10 was triggered.

After I run DolbyVision script Workflow 1 (and provided 2x the same input file for HDR10 and DV input file) the processed file on right did trigger DV playback.

in my opinion this forum had 3 great contributors:
1 -@Yusesope
2 -@Quietvoid
3 _@RESET_9999
Yusesope we dont know what happened to him. He is Italian like me but I cant trace him in Italy.
Quietvoid does not like to write too much in the forum.
And then RESET_9999 who is carrying the forum forward and almost in solitude.

Maybe different containers?

Does anyone know if Google TV devices support Profile 8.1?

Specifically, do Sony TVs with Google TV support DoVi Profile 8.1 in an MKV container?

I've tried playing it back via Plex, and it triggers DoVi, but I'm not sure how to tell whether it's just triggering DoVi like Plex on Apple TV or if it's actually passing along DoVi metadata.

Thanks!

Thanks for sharing but that unfortunately doesn’t mention Sony TVs. I’d be more than happy to test if someone could explain how.

I have Philips 65oled934 2019. It has an LG Panel, but I can perfectly playback P8 and P5 MKV. The compatibility corresponds with Chromecast with GTV, Fire Stick TV, Zidoo Z9X -ish.
How I can find out if EL is being dropped with P7?

Often the best way to check is visually.
I don't know Plex but maybe it has settings to disable/enable Dolby Vision. In which case you can directly compare the two. If not, or when having other doubts, a safe bet with Profile 8.1 is to create a copy of the file where you strip RPU and compare to that.

This can raise some confusion.
P7 EL carries RPU and DV playback always requires RPU. What you probably mean is, whether the additional video data FEL holds will be processed or not. From RESET_9999's device list, of the three players you mentioned CC+GTV is the only that does process FEL. But it has to be in STDL. Can't vouch for it though.
As I have a Z9X I know for sure it doesn't decode FEL. Like most non-UHDBD DV players.

Then it would be probably the same for me, no FEL decode. Still wondering why LG TV can't playback dv in mkv. I guess not much people have philips tvs.
Still, how can I find out if the fel is processed or not?

Not sure. Maybe the manual or specs provide with more info. Perhaps the tv shows meaningfull data during DV playback.
A visual comparison of displays from P7 FEL source and its P8.1 counterpart could also tell you more.

Don't know it. But looking at it and given the name, I'm pretty sure it's a tool for extracting only the subtitles that are flagged as "forced" in a PGS stream. PGS (aka SUP) is the subtitle format used on (UHD)BD.
