Why Audio offset in your script is it 1100ms?
What's wrong with 0ms?
For some reason, extracting through ffmpeg causes the audio to be offset from the video. Have not figured out exactly why, but the 1100ms offset fixes it.

What is the correct L5 data for an RPU in a video that switches between IMAX (16:9/full screen) and black bars (2.35:1)? Should I be cropping the RPU (0,0,0,0) or matching the black bars (0,0,280,280)?

I guess this has already been answered.

Alternatively I'm pretty sure leaving the L5 to 0 also works.

But you don't have to do any of this since the content is already Dolby VIsion :!:
What about a video where the x axis isn't fully used (148,148,0,0)?

I don't understand what you mean by this.

I'm trying to describe a video where there are black bars along the sides and not the top and bottom. I don't remember seeing much conversation about editing the side values. Maybe I'm over thinking things.... Just edit those L5 values?

It's the same principle regardless of top/bottom or left/right.
Just edit them for the letterbox bars in the video.

on my old firestick 4k I am using the kodi version (20.0 Alpha1 (19.90.101) Git 2021 1007-50679851c6 compiled 2021-10-07) posted by yourself on this forum months ago.
Strange problem affecting the automatic frame rate:
Same Dovi profile 8 file in 2 different containers .mkv and .ts
The mkv plays properly in Dolby Vision and 24Hz
The ts starts in Dolby Vision at 60Hz then, after a few seconds it changes to HDR and 24Hz
This happens with all my files, tested extensively.
Have you got an explanation for this?
Can this problem be sorted out?
Thank you

PS. This problem does not exist in the new Firestick 4k

I've got the UBR-X110, and trying out the DV samples from makemkv via the network interface:
- P4 - Audio/Video worked, no HDR, no DV
- P5 - Audio worked, Video colors off, no HDR, no DV
- P7 (MEL) - Audio/Video worked, HDR worked, no DV
- P7 (FEL) - Audio/Video worked, HDR worked, no DV
- P8.1 - Audio/Video worked, HDR worked, no DV

So no DV on any of the profiles. Womp womp.

Someone else asked but the port is Gigabit. It's showing GbE in my Unifi console.

So I have a question I have a few files withdolby vision hdr :

Format profile : Main 10@L5@High
HDR format : Dolby Vision, Version 1.0, dvhe.05.06, BL+RPU

These play with a green shine, is there any way to just rip the dolby vision out?
Tried a few ways even those (i believe) mentioned in this thread but none seem to work.

@RESET_9999

Have you tried adding ^" to set /p in your script?

I just injected an RPU, "RPU.(2020)" into a video, "video.(2020)\video.(2020).mkv" with this edit of your script, and it seems to work.

No, I'm afraid not. Those are profile 5 files, and they are only suitable for Dolby Vision playback because they don't have a embedded HDR10 fallback like profile 7 or 8 files do.

Hey I have that too with p5 or p8 mp4. You can just drag and drop the file into mkvtoolnix and remux to mkv. It will play without stutters and the dolby vision will be kept. I usually playback those with just Player or vimu. Mkv work a lot better than mp4

Just got a note back from support after trying a couple other remuxed formats:
thank you for your message.
We are sorry to inform you that Dolby Vision in video files playback is not supported.
Dolby Vision is only supported with UHD 4K Blu-ray discs.

Some devices can tonemap it on the fly to HDR10 or SDR such as the Firestick TV (latest one), Sony x700/x800m2, Windows 10 Movies and TV app.

Yep, I have the same problem with some DV MP4. I switched to the TS container and I never had the stuttering issues again with DV. You just have to keep the subtitles externally.
