Would that work for you?

I saw a major kernel change in LibreELEC-RPi4.arm-10.0-nightly-20210724-0b9677f.tar, going to aarch64. Is it including More vc4 fixes by mripard · Pull Request #4470 · raspberrypi/linux · GitHub, supposed to fix RPi4/kms: boot hangs if two monitors are connected · Issue #4465 · raspberrypi/linux · GitHub ?

I could try, but I have to admit that I'm not looking forward breaking and restoring from backup the lounge system on a Saturday evening! That would no do much good to my WAF...

Thanks!

Hello!

I'm in the dual HDMI TV+old AVR situation and bumped into the exact same problem. The other single HDMI RPi4 had no issue.

I reverted to an older build.

I'm watching this thread so that I can provide an additional data point if needed.

So the SoC has no hardware deinterlacing filter? Bummer!
Getting out of the hardware chain is probably crap...

Is handing over interlaced content to be deinterlaced downstream just as crappy to achieve?

nightly-20210630-d4c4658 fixed it, YAY! Thank you all involved!

I'm not trying to put any pressure or show a lack of understanding about the current priorities, so please don't shout at me too loudly! I'm just asking to update my expectations...

(it is, after all, only my 4yo daughter who's watching interlaced material, and she hasn't complained to me yet! I do cringe every time I look at the screen, but all gets better once I switch my attention elsewhere...)

Is there any progress on the RPi4/V4L2 deinterlacing front, has it moved up in any significant way in the to-do list, or are there still so many other more basic/important things to sort out first?

Thanks!

Yup, more an AVR issue than LE10.

I have an Intel NUC connected to the AVR too, receiving an EDID just as confusing as the RPi. Same workaround: fixed EDID file from before the TV was changed!

Well, I hope that the post will help people bumping into this use case!

Apologies offered, the forum software was giving me a 524 timeout error when I tried to post this, I did not see that it was anyway posting multiple versions... So, so sorry...

Hello!

I am using an RPi 4 in a dual headed scenario, I can't upgrade my HDMI 1.4 Denon AVR-2310 (2009) at the moment:

• RPi 4 4 GB
• TV on HDMI0
• AVR on HDMI1
• nightly-20210426-090e00d

I am switching from a 2007 Toshiba FHD TV to a new Sony XH90 4K HDR.

I am experiencing an EDID issue. I had mentioned it a few days ago, but this time I have debug logs and data points, as well as a work around:

Case 1 - Single headed - Toshiba 1080p TV - Video and audio through AVR - Working

• Pastekodi - http://ix.io/3ewO
• EDID Denon AVR - DenonOnPi4-EDID.bin
• EDID Decode Denon AVR - Ubuntu Pastebin

Case 2 - Dual headed - Toshiba 1080p TV - Video to TV, sound through AVR - Working

• Pastekodi - http://ix.io/3exh
• EDID Denon AVR - https://www.youplala.net/~nico/LE10/DualDenonOnPi4-EDID.bin
• EDID Toshiba TV - https://www.youplala.net/~nico/LE10/DualToshOnPi4-EDID.bin
• EDID Decode Denon AVR - Ubuntu Pastebin
• EDID Decode Toshiba TV - Ubuntu Pastebin

Case 3 - Dual headed - Sony 4K HDR TV - Video to TV, sound through AVR - Video OK, no sound on AVR

• Pastekodi - http://ix.io/3lht
• EDID Denon AVR - Dual4K-DenonOnRPi4-EDID.bin
• EDID Sony TV - Dual4K-SonyOnRPi4-EDID.bin
• EDID Decode Denon AVR - Ubuntu Pastebin
• EDID Decode Sony TV - Ubuntu Pastebin

Case 4 - Dual headed - Sony 4K HDR TV - EDID trick - Video to TV, sound through AVR - Working

• Pastekodi - http://ix.io/3lhu
• EDID Denon AVR - https://www.youplala.net/~nico/LE10/DualDenonOnPi4-EDID.bin - From Case 2, forced
• EDID Sony TV - Dual4K-SonyOnRPi4-EDID.bin
• EDID Decode Denon AVR - Ubuntu Pastebin - From Case 2, forced
• EDID Decode Sony TV - Ubuntu Pastebin

The AVR EDIDs of Case 2 and 3 are quite different.

It's to be noted that the AVR also has its output connected to the TV. I'm guessing that it is creating an EDID mixing the TV's capabilities. In case 3, that must be confusing LE10 no ends. But is it really LE10's fault? I'll leave that to your judgement.

My workaround is to use getedid and acquire a working AVR EDID, then manually force it upon LE10. I'm afraid that I may gather mismatched delay data on the way and have weird lip sync... But heh, still better than no sound!

Have fun with this!

Thanks!

Riiiight...

I've started collecting the pastekodis with debug logs, EDIDs, etc. for single headed and dual headed using the old 1080p TV.

That way a good chunk of work is already done for when I get the 4K HDR TV back in to play.

I'll reopen a thread when ready.

It would be great to get some more feedback if it all works (so far I think I'm the only one who tested this) or if there are issues I might have missed.

It works to create and delete for single headed and dual headed cases. Fantastic!

Yup, it worked for me, rebooting fine with everything in place even with the AVR and TV in stand-by!

All files in their right places, with the expected content.

Relevant dmesg lines:

[    0.000000] Kernel command line: coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_compat_alsa=0 snd_bcm2835.enable_hdmi=1  smsc95xx.macaddr=DC:A6:32:1A:2F:7C vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000  boot=UUID=1403-5701 disk=UUID=cdb3ef9c-e4d9-46d8-8b6f-020a65636ade quiet  drm.edid_firmware=HDMI-A-1:edid/edid-HDMI-A-1.bin video=HDMI-A-1:D root=/dev/ram0 rdinit=/init usbcore.autosuspend=-1
[    1.509751] [drm] Got external EDID base block and 1 extension from "edid/edid-HDMI-A-1.bin" for connector "HDMI-A-1"

I'll most probably test the delete function and dual-headed scenario later today, then report back!

Thanks for this!

MikeKL you make a valid point.

Well, up to the moment when the same sort of setup works with a different TV, hence my head scratching...

I had gone through that thread already, but will do again, I may have missed an important bit.

Thanks!

I'll test that today on my RPi4 and tell you how it went!

This is probably more for HiassofT ...

You mentioned EDID scripts for LE10 on RPi4 here:

Post

RE: HDMI Passthrough RPi4 - AVR detection

Thanks a lot for reporting back and I'm glad it's working now!

I expected that the video= option is needed, without it linux doesn't detect that AVR.

I'm currently working on a script to simplify this whole edid stuff - hopefully that should make it into beta2.

I'm not 100% sure why hdmi_ignore_cec_init doesn't seem to work - make sure everything's set up correctly in kodi's CEC settings (though CEC should only be ever used on hdmi0 in kodi/linux - so it's puzzling why your AVR turns on).

so long,

And I see this GitHub commit:

Merge pull request #5264 from HiassofT/le10-edid-cpio · LibreELEC/LibreELEC.tv@51e371e · GitHub

Is there a bit of documentation on how to use it?

Would it work in fixing EDID for both HDMI connections in case of a dual-headed setup (HDMI0 on TV, HDMI1 on receiver)?

Many thanks!

Hello,

Due to logistical issues, I come with no logs at all, so this is more a question on principles. I'm bracing for "no logs, no problem!"

Running L10 nightly (20210424) on RPi4 4 GB.

HDMI0 connected to TV

HDMI1 connected to Denon AVR-2310 receiver (a 1.4 model that won't deal with 4K HDR or ARC, let alone eARC)

The goal of dual heading is the classic avoidance of a receiver upgrade...

Case with 4K HDR TV - Sony XH90

TV and receiver turned on and set to proper inputs before powering the RPi to avoid EDID issues.

Drool-worthy 4K HDR video. Wooooo!

All the audio settings, Normal and passthrough, show the availability of the Sony TV and Denon receiver. I chose the Denon receiver.

I get no sound. No GUI sound, no passthrough.

I've reset my receiver's processor and completely, no positive result.

Case with old 1080p TV - Some Toshiba from 2007

Only the TV is different from the above.

The receiver produces all the sound, GUI and passthrough.

Riiiiiiight.... I know, no logs... I promise to generate them properly, full pastekodi and all, full EDID info, etc. if/when I can logistically put the 4K TV back in play. I fully that this is the only way to make real progress.

But!

Is there any known issue that I should be aware of?

When/if I can get the 4K TV back, is there anything in particular that I should be careful with? Any trick? Any specific data that I could collect outside of a pastekodi or 2 with debug logs and EDID?

Thanks!

Best place to track would be to create a github issue Issues · LibreELEC/LibreELEC.tv · GitHub - please add a link to the sample file there, too and a link to this forum thread

Done!

Hello, is there a place where this bug is tracked?

I'd like to avoid annoying you here about it while it's being worked on.

I've looked at the Github issues, but things are pretty scarce over there.

Thanks!

Nico

BTW, I forgot to say that the video plays when I turn "Allow hardware acceleration with DRM PRIME" off.

Changing the "PRIME Render Method" has no effect.
