Dolby Vision Profile, VS10, plus other info on skins

[Vaso68]

Is there any topic about it? I would like to know more

[ashlar]

What are you talking about?

There’s not much detail, but see @Portisch 's last two posts here:

Nightly builds (NEW)

Tomorrow nightly 20241017 will have a new, experimental dynamic video/audio buffer handling. This new kind of buffer handling will hopefully solve issues about not balanced number of video/audio packages in some streams. Mostly streams with Dolby Vision FEL and TrueHD show such behaviour. Also media with high bitrate should play more smooth now.

Dynamic cache can you see in the playerdebuginfo. It separate from kodi cache.
Use cpm’s estuary A5 modded skin, I added there one button for that.

Button mapping script to toggle VS10 Engine On/Off v1.1

New: Added ability to toggle VS10 Engine on/off during video playback by remote. The updated script has to be mapped as both Global and Fullscreen Video shortcuts.

Description: This script changes the Kodi Settings > System > CoreELEC > For SDR8, SDR10, HDR10, HDR10+, HLG between off and the previous value. The VS10 status notification pop-up is anchored to the state of SDR8.

Comment out any settings in the script you don’t wanted toggled.
example: to only toggle VS10 Engine on/off for SDR8 and SDR10 videos:

SETTINGS = [
    "coreelec.amlogic.dolbyvision.vs10.sdr8",
    "coreelec.amlogic.dolbyvision.vs10.sdr10",
    #"coreelec.amlogic.dolbyvision.vs10.hdr10",
    #"coreelec.amlogic.dolbyvision.vs10.hdr10plus",
    #"coreelec.amlogic.dolbyvision.vs10.hdrhlg",
    #"coreelec.amlogic.dolbyvision.vs10.dv"
]

Setup Instructions

1. Open Keymap Editor Kodi Addon, and map Minimise to the remote button you want to use to toggle VS10 on/off

   a) Edit > Global > System > Minimise > Edit key
   b) Edit > Fullscreen Video > System > Minimise > Edit key
   Save & Exit Keymap Editor

2. Open SSH, copy & paste the command below:

   sed -i 's|>minimize<|>runscript(/storage/.kodi/userdata/keymaps/toggle_vs10.py)<|g' /storage/.kodi/userdata/keymaps/gen.xml
   

3. Copy toggle_vs10.py to:

   Samba Userdata/keymaps/toggle_vs10.py
   [/storage/.kodi/userdata/keymaps/toggle_vs10.py]

4. Restart Kodi

Hi folks, new AM6B+ user (1 week) and been experimenting with CoreElec dual boot added via SSH on eMMC card (fastest speed) and chose the CPM build as well for having the option of DV on HDR+.
I think I have done all the correct settings on my box/setup, but I seem to be having some issues while playing high bitrare remuxes Profile 7 FEL - in my case the file playing is 1917.

So the issue I am facing is constant every ~5 mins playback interruptions cache 0%. I have uploaded some screenshots of what settings I have and the Player Process Info as well. Apologies in advance if my post is in the wrong thread.

[MauriceW67]

Start by testing with buffering completely disabled.

EDIT: Also, try showing PlayerDebugInfo, it will show the status of the new dynamic caching implementation separately for audio and video.

[korbus]

You can also try increasing the chunk size to 512 KB or 1 MB.

[mvanbaak]

Set the chunk size to 1MB. This fixed the exact same problem for me.
I have my storage mounted through NFS, which also needed this change to 1MB.

I’m not close to my device so I cant get the exact settings where I changed this.

@krazzer

I have uploaded some screenshots of what settings I have and the Player Process Info as well.

Btw, which skin are you using?

[krazzer]

Unfortunately can’t find any info on how to activate the Player Debug info. I already tried turning off cache with same results. I should have mentioned that I am using my own pc as server and playing files through Composite Plex. Not sure if that would make the difference. Also tried the other Plex add-on with same results.

[krazzer]

Thanks I have tried already with same result.

Latest build for CPM A5 -Horizon 2

[MauriceW67]

Maybe Plex is the issue. You could try creating an SMB share on your PC or installing an NFS server such as Hanewin NFS and access the files through that.

[korbus]

Try using this addon (the latest update, 0.8.0 beta 3.8, not the old one from Kodi’s repository). I am using it and it works really well for my library. Also you can get help there from the dev and other users.

[krazzer]

Thanks for the suggestion, never done this before - are there any guides?

[krazzer]

Will install now and come back. Guess if nothing works will try to get a SMB from my Windows computer without the added Plex layer.
L.E. installed the latest PM4K same issue with buffer reaching 0%…also the default media player lacks in so much info from the usual Kodi player.

The written guides mentioned that remux P7 FEL were working without any issues with Plex, so unsure where the fault is.

For returning to “base” CoreElec without CPM anyone knows on how to do it?

It lacks nothing if you install Plextuary CPM skin from his repository (Don’t panic repository) - it’s just a very slightly modded Estuary skin.

@krazzer

Just download the latest CoreELEC stable or nightly, access the box through samba/ssh, copy that file in the Update folder of the box and reboot it.

[Vaso68]

Ok so what exactly you mean by the disabling cache to activate dynamic ? Memory size can be only set or set to store on disk. Can’t see any option as disabled… Oh or do you mean to set the first option to No buffer?

[frodo19]

Yes.
Still use the system, one small amount.
