rpi4 with LE 11.0.1: how to create whitelist (modelist)?

ko56 · April 19, 2023 at 11:37 PM

Hi, I have an RPI4 running LE 11.0.1. I have a Samsung KS8000 TV that can support various 4K modes. E.g.

LibreELEC:~ # tvservice -d edid.dat; edidparser edid.dat

shows things like

Code

HDMI:EDID found CEA format: code 95, 3840x2160p @ 30Hz
HDMI:EDID found CEA format: code 93, 3840x2160p @ 24Hz
HDMI:EDID found CEA format: code 94, 3840x2160p @ 25Hz
HDMI:EDID found CEA format: code 98, 4096x2160p @ 24Hz
HDMI:EDID found CEA format: code 99, 4096x2160p @ 25Hz
HDMI:EDID found CEA format: code 100, 4096x2160p @ 30Hz

How do I enter mode lines in config.txt to enable smooth 4K video playback? Right now it pauses every few seconds, and then resumes.

(I do have desktop resolution set to 1080p @ 60fps, and the Refresh setting to "On Start/Stop")

Kodi Settings > System > Display > Whitelist

Select 3840@30/25/24 and 1080@60/59.94/50/24/23.976 and enable "Allow double refresh rates" and leave the GUI resolution at 1080@60

Thanks, I know about that. The problem is that Kodi Settings > System > Display > Whitelist does not show anything beyond 1920x1080.

Does your HDMI cable also support 4K? They are often called HDMI 2.0 or 2.1 cables in the shops.

If not, then you get reduced data bandwidth, resulting in a reduced whitelist.

Also ensure you are using the HDMI port nearest the power connector.

OK, the whitelist problem is resolved. By removing all cables from the connection (it involves an A/V receiver as well) except the HDMI cable from the rpi4 to the TV, the whitelist now includes the "4K" modes. So I just have to find which of the other cable pieces is the problem.

Thanks to everyone for their help.

However, even with 3840x2160@30 selected, the video, which says it is 3840x2160 HEVC, is still pausing. Kodi every few seconds displays the the "loading circle", it reaches 100% quickly, but playback is still not viable.

Please provide a full debug log.

How to post a log (wiki)

1. Enable debugging in Settings>System Settings>Logging
2. Restart Kodi
3. Replicate the problem
4. Generate a log URL (do not post/upload logs to the forum)

use "Settings > LibreELEC > System > Paste system logs" or run "pastekodi" over SSH, then post the URL link

Banned add-ons are installed. No support will be provided.

ko56 · April 23, 2023 at 2:49 PM

Would you explain? I'm not aware that I have any banned add-ons.

I believe I have removed all "banned" addons. Please verify: the new log, hopefully showing the problem, is http://ix.io/4ucP.

**chewitt** · April 25, 2023 at 10:10 AM

Nope. Still there.

It would help me if, at this point, you would point out what needs to be removed.

Ok, done. New link at http://ix.io/4uhK

Does anyone have any idea of what the choppy playback problem may be, given the posted log?
