Re: Dolby Vision now possible through MP4 Mux.

Is that the only file one has to revert and then it will work for LG CX with FEL and all that? Also, I can't find a 2018 version, seems they routinely updated it without versions :< https://github.com/DolbyLaboratories/dlb_mp4base/tree/98fc2f52f318f41eeedcfc44bc2f430d7ca4eabd/bin I don't have a CX ...

Re: Dolby Vision now possible through MP4 Mux.

So I needed to find a way to change hev1 into dvhe inside the EL video track inside the MP4 container. I could not figure out any command or switch in mp4muxer or m4box to do so (there might be one) so I decided to go a different way. Mentioned a while back but you could have just used the 2018 ver...

Can we playback single layer DV (profile 5) mkv (!) with Firestick4k? If so, how? Thanks
Yes you can, with Kodi (https://forum.kodi.tv/showthread.php?tid=360018) or Plex.
There is also a demo ExoPlayer app but it has to be launched from Kodi and requires a specific config for that.

Re: Dolby Vision now possible through MP4 Mux.

Thanks! Do you know if those custom builds only work on Shield, or can I sideload it on TVs (such as my sony x900h) with android TV? They work on the Shield and Firestick, at least these: https://forum.kodi.tv/showthread.php?tid=360018 Some reports that it works for some on Sony in that thread, you...

Re: Dolby Vision now possible through MP4 Mux.

I wonder is possbile to force non-dv video to play as dv via kodi on Shield TV? I don't know about the Shield, but the Firestick only triggers Dolby Vision for the TV when there is proper metadata. Otherwise, there is an option to have Dolby Vision enabled all the time. I don't think the Shield can...

Re: Dolby Vision now possible through MP4 Mux.

What was the issue that needed patching? The Firestick Dolby Vision decoder panics and renders a black screen when it encounters a file that contains both Dolby Vision and HDR10+ metadata. The source of the --skip-hdr10plus switch :) I basically implemented the same behavior on the fly before the d...

Re: Dolby Vision now possible through MP4 Mux.

Eventually you might be able to get on the fly conversion from profile 7 to profile 8.1, at least with Kodi. Then all files would be compatible with most devices at playback. I don't believe streaming devices will ever get full support for profile 7 FEL. I've already patched my Kodi to fix the DoVi/...

Re: Dolby Vision and 1.15.1

I hear a version of Kodi 19 Matrix currently in beta and almost out of it is able to finally play dynamic DV files, but I have installed such version and everything I had with DV, plays as standard HDR. Did I do anything wrong? I have a Shield 2019 Pro so that should not be the issue I took on the ...

So yes the FEL can make a HUGE difference.
But does it work on the Shield after all?

Re: Dolby Vision now possible through MP4 Mux.

you got me curious. I checked that scene on my x700 and I find FEL DV sightly cleaner than HDR10 and P8 DV. thank's @lexyz for the samples HDR10 vs P7 FEL: https://screenshotcomparison.com/comparison/10301 a lot more obvious with the capture card.. wow: https://screenshotcomparison.com/comparison/1...

Re: Plex on Fire TV Stick 4K - DV or not?

You can't use refresh rate matching in both the stick and Plex's settings, otherwise it doesn't work all the time.

Either way, working files would only be profile 7 MEL as mentioned previously.
Other profile 7 files would still trigger Dolby Vision, but show a black screen.

Re: Plex on Fire TV Stick 4K - DV or not?

Nope. You should see the mode switch pop up, no matter the input device.
No issue with a C8 and the stick for me.

Re: Dolby Vision and 1.15.3

I noticed that when makemkv 1.15.4 opens a BDMV it correctly lists the EL type: FEL or MEL, but when that disc is processed to an .mkv it shows only EL (BL+EL+RPU). Not sure if it has any bearing on anything. Sadly that .mkv plays as HDR (not DV) on Oppo UDP-203, not sure if the latter support DV t...

Re: Dolby Vision now possible through MP4 Mux.

420 is not wrong, the patent specs also only mention 12 bit YCbCr 420 reconstructed output.
As for the HDMI transmission, it is detailed as 12 bit YCbCr 422 because the metadata is also transported into the least significant bits.
