LE 10.0.2 on RPi4 not playing files that 10.0.1 had no problems with.

Azurewrath · March 18, 2022 at 2:06 PM

Hardware: Raspberry Pi4B, 4GB RAM

LE/Kodi Version: 10.0.2/19.4 and 10.0.1/19.3 (both my existing installation and completely fresh installs)

I've found that some files do not start playing on 10.0.2 that worked flawlessly on 10.0.1. It looks like the HDMI Signal completely blanks out.

Funnily enough, as i found out by accident: When i start playing a file that works and then, while still playing, i select and start the problematic file it works as well.

You can find one of the problematic files (or, well, a 10 second sample i cut from it without re-rendering that shows the same behaviour) here:

Try a different, HDMI Premium certified ,HDMI cable. RPi4 will now output 10/12bit video which means you'll see issues like that with cables that don't meet the specs.

I might try that, but i highly doubt that that's the issue.. since other 10bit HDR files play fine.

This one, for example, is playing perfectly:

Just tested your sample and got the same "no signal" issue here. Not quite sure what's going wrong, I've informed RPi devs about it.

Azurewrath · March 18, 2022 at 10:33 PM

Thanks.
Oh and just fyi, i just tried the latest LE 11 nightly, same problem.

Azurewrath · March 21, 2022 at 4:45 PM

Just received some "Ultra High Speed" aka HDMI 2.1 cables and adapters. (Micro-to-Fullsize, Fullsize-to-Fullsize with Adapter)

Same issue: Files work fine in LE 10.0.1, don't play at all in 10.0.2 and 11 Nightly.

Oh and, is there some kind of bugtracker where this issue might be listed? Just so i could track the issue myself without nagging people about it.

**popcornmix** · March 24, 2022 at 5:00 PM

I think this is a display issue rather than a video decode issue.

Azurewrath can you remove hdmi_enable_4kp60=1 from config.txt, reboot and try this file again?

Azurewrath · March 24, 2022 at 5:12 PM

The hell.. you're a genius.

Just did, now the file plays fine in 10.0.2

Strangely enough when hdmi_enable_4kp60=1 is enabled it never plays, no matter what resolution or framerate i set for the GUI or if framerate change on start/stop is enabled or disabled or whitelist is enabled or not.

Also, the file is 23.976fps, so that shouldn't matter as well..

Would you say this is some kind of Kodi or LE bug or a RPi4 issue? Or a combination?

**popcornmix** · March 24, 2022 at 6:12 PM

Probably a kernel display bug, but I'm currently confused.

I just noticed the file played fine for me initially (where I didn't have hdmi_enable_4kp60=1) then later on a different setup did fail.

Looks like the more common 3840x2160@23.98 video doesn't have this failure, but yours of 3840x1744@23.98 does.

I'm guessing the resolution is having some effect on clocks or timing.

Jis26 · March 31, 2022 at 11:59 AM

I use Libreelec on an rpi4b.

Yesterday I did the proposed update to 10.0.2 and since then the 3840x2160 24p video no longer switches to 24p but stay in 50p. In 1080p no problem, the tv goes well in 1080p24. Did you have the same problem or do you have a solution please?

I posted on another topic but got no response.

**popcornmix** · April 7, 2022 at 4:29 PM

Azurewrath can you try this test build.

I think the issue was your video was 10-bit but not HDR, which is a little unusual.

That meant the kernel didn't do a full modeset (as HDR colourspace didn't change) but did change the colour depth (which adjusts the pixel clock) which really wants a full modeset.

The test build is a stanard Matrix build with a kernel patch added to force the modeset.

Azurewrath · April 7, 2022 at 5:15 PM

popcornmix Just did, all the variations just to make sure.

10.0.2 -> plays

10.0.2 with hdmi_enable_4kp60=1 -> fails

test build -> plays

test build with hdmi_enable_4kp60=1 -> PLAYS

Very cool, seems that fixed it. Thank you very much, looking forward to a release with the fix included.

LE 10.0.2 on RPi4 not playing files that 10.0.1 had no problems with.
