Dolby Vision now possible through MP4 Mux.

[skull88]

Makes sense, I don't blame you either for leaving it in the past. Not to mention, a tool like that may have an unintended consequence of more "experts" and groups around the interwebz to modify retail values and spread misinformation about what they should or should not be.

Is there an easy ffmpeg command to convert an .mp4 with embedded DV (profile 5) to .mkv?

Looks like ffmpeg doesn't support dvh1 codec in mkv.
Try something like:

Code: Select all

ffmpeg -i dvh1.mp4 -c copy -vtag dvhe dvhe.mkv

I don't know if the mkv will play proper Dolby Vision though.

Try using mkvtoolnix

Try using mkvtoolnix

This worked! I didn't realize MKVToolNix could open files other than MKV, but sure enough it can!

Regarding the setup im using, do you think i need to change anything?

No , it sounds right but you should try DV MKV with kodi on your C2, it works great on my end (PGS and SRT).

Hi again @RESET_9999!

I followed your advice and installed Kodi in the my C2 but im having some problems regarding the resolution and refresh rate options in the app..

In the display settings, only the 1920x1080p resolution is available, and in the whitelist options it only shows 1 available (1920x1080, 0Hz). When i playback some movies, i managed to get DV but the refresh rate doesnt switch, even though i turned on that setting in the player. Using the player info, i can see that it reads correctly the video stream (4k) but the screen information says 1080p and 60hz. It doesnt seem like an error because the movie is looking a bit blurry indeed..

Are you able to get 4k resolution and 24hz refresh rate in your setup?

yes

[tjreis2]

Can you tell me what is the version of kodi that you installed, and if it was via webos dev manager?

I also have my lg c2 connected to an avr and i think it might be something related to its connection..

[RESET_9999]

21.0.3beta

was via webos dev manager?

yes, im connected to an AVR too via ARC

Hi,

I'm experiencing raised blacks in DV with some movies.
I'm using an Oppo clone connected to a Nexigo Aurora Pro UST projector.

Full Disc Rip - BDMV

I've noticed this recently when watching :
- Mission Impossible : Dead Reckoning
- True Romance

The letterbox bars and opening credits etc are very raised to a medium grey.

When I switch from TV led to Player led it improves.

Any ideas?

[scaramanga]

Apologies to Reset - I know you mentioned to use Doom forum but it's a 5 day wait after registration so trying in here first.

I've got a setup of Shield 2019 through to LG TV utilising a Plex server and it can happily play native DV rips (Dune) and standard UHD rips (Sicario) from MKV
no issue.
When I have ran Sicario through the script (3-1) the film does trigger DV on the TV but there are blocky aspects when it comes to dark colours on light background and a few frames that are obviously awry.

Just wondered if I am doing something wrong in prepping the scripts, or do I need to invest in a Nvidia GFX card or a SSD to carry out the conversion work?

Thanks
