Hi, does anybody already have the new firmware (03.34.55) for C1 and if so, does it fix the L1 bug on x700?

Perhaps somebody knows.
But I've created a few movies with the dovi_scripts.
They are single track dual layer profile 8.

I have muxed them to m2ts for playback on the Shield.
The ones with DTS-MA play properly.
However the ones with Dolby TrueHD seem to only play audio, the picture is frozen.

Any ideas?

How did you do that? I thought P8 was a single layer format.

Regarding the audio issue, it can be helpful if you post the connection chain. It's a bit of a guess now.
I don't know the Shield. But because DTS-MA does work I'd wonder if the tv is the culprit here. Should your Shield connect to the tv directly, it may be possible the tv is able to handle DTS-MA (probably because of the dts core) but it can't handle a TrueHD stream. Should you have muxed TrueHD with embedded AC3 (as opposed to TrueHD only) possibly audio will work if you'd select that AC3-track for playback on the Shield.

Agree, TrueHD with AC3 core would be the best approach.

DV8 is by definition STSL, BL+RPU, so I don't think that was intended.

Has anyone run into issues with the Sony X700 or X800M2 where 4K files that aren't exactly 2160p resolution get down-res'ed to 1080p? Any fix for this with DAR/SAR headers?

I have a file that's 3840x2080 instead of 2160 and the X800M2 is playing it back with DV but outputting 1080p.

DV test files

edit: Apple devices will need to remux files first in mp4box
Best for apple device since iphone4 is Subler. It has mp4 compatibility with dolby vision / atmos although i dont tested it now since departure to android.

Pitty your player doesn't just pad with black bars. Or even perform a minor stretch. Sony players have always had a reputation showing unforbidding behaviour towards non-compliant media. They clearly haven't changed. Without recoding, I very much doubt if a fix is possible for your video.
Where I assume it needs to be muxed in (m2)ts. Mkv does offer some tinkerings on container level, however there are very few players that honour certain headers.

Hey guys, :D hope ur day is fine :oops:

anyone knows how RESET_1999 do to get number of dynamic frames inside a movie (rpu.json) ?

like he does here

=> https://docs.google.com/spreadsheets/d/ ... edit#gid=0
=> Bad.Times.El.Royale.2018 iTunes Shots static DV: only 9 shots for the whole movie.

https://justpaste.it/47641

====

what's the commandline to use on my RPU.json to get the exact number of dynamic shots like he does ? :mrgreen:

strange, my x800m2/x700 doesnt downscale to 1080p with cropped 4k videos but it makes the letterbox grey and it's unwatchable.

I'm guessing you're trying to plot DV (6-2-3) ?

1-Uninstall any python version you have and reboot.
2- get and install python: https://www.python.org/
3- Open a CLI windows and type 1 by 1 all the required modules:
EG:
pip install ijson

yes... 6-2-3

tried that... no luck... :-/ models keeps asking for missing "base", then "props"... both installed ok, but "references" are a showstopper
