  • Help find EDID from monitor

    You can use the internal script "dump-active-edids" (it's used by "getedid" on RPi) to write the edids of all connected displays to /storage/.config/firmware/edid

    It'll tell you which HDMI/DisplayPort/... connections it detected, for each one it created a edid-<NAME_OF_CONNECTOR>.bin file - which you can then simply decode with edid-decode.

    eg here on RPi4 with one display connected to the first HDMI port (edid-decode cut down for brevity):

    You could also check through all the connectors in /sys/class/drm/, verify if the status reports "connected" and then use the edid file from there (eg /sys/class/drm/card0-HDMI-A-1/edid) - this is basically what that script does - but as card, and connector names may change it's probably easier to let the script deal with that :)

    BTW: so far we only tested the script on RPi, it should work on all other devices though, so if you have issue or notice something odd please tell us about it so we can fix/improve it.

  • LE 10.0.1 / Rpi4 / No picture after update from LE 10.0.0

    Thanks, this is interesting and useful information - this thread has become a bit convoluted, but most issues seemed to affect older (Samsung) models.

    Could you please test with the latest LE11 nightly build from here https://test.libreelec.tv/11.0/RPi/RPi4/…/11.0/RPi/RPi4/ ´(currently 20221215, scroll down to the end of the page) and if doesn't work test if the workaround of setting a different mode in config.txt works?

    Add the following to the end of config.txt

    Code
    hdmi_group=1
hdmi_mode=20

    Also test (without those config.txt changes) if unplugging and replugging the HDMI cable gives you working video output, if yes set the display resolution in kodi to something different than standard (eg 1920x1080 at 50 Hz instead of 1920x1080 at 60 Hz) and report back if that works, too.

    Anyways, we'd need logs (with debugging enabled in kodi) of all working and non-working cases.

  • Raspberrry pi 4: cannot boot LibreELEC anymore

    Test with a different HDMI cable and if you are using a case also without the case.

    Argon cases have a long history of causing HDMI issues because of low manufacturing quality of their internal adapter PCB, but as I just experienced myself even cases without internal adapter boards can cause HDMI issues as they often won't let you fully plug in the HDMI connector - even half a millimeter or a millimeter can make a huge difference.

    And it gets even worse if the HDMI cable is a bit worn out and starts to fall out easily.

    I just had that issue here with a "full armor case" and both a new and an older HDMI cable, and also with a USB3 cable - have to say I absolutely hate the HDMI and USB connector crap, it's as bad as SCART was in the old days, non-interlocking connectors just cry for problems. Display port did it right, same goes for ethernet, VGA, DVI etc but the consumer connector crap is starting to really annoy me...

  • HDMI Splitters and audio

    What kind of splitter / audio extractor are you using?

    The splitter needs to mix the EDIDs of both the AVR and and projector, LibreELEC heavily relies on that being accurate and it is quite likely Windows was more relaxed about it.

    My HDFury Vrroom has very extensive settings how it'll mix (or patch up) the edids and also allows you to download the edid directly via the web interface.

    You can also grab the edid presented to your chromebox from /sys/class/drm/cardX-HDMI-A-Y/edid (A, X, and Y may vary on your system) and decode it with edid-decode. eg

    Code
    edid-decode /sys/class/drm/card0-HDMI-A-1/edid

    if you have multiple cards or connectors (A-1, A-2 etc) try all of them and post the output (the unconnected HDMI ports will show "empty" - just ignore them).

  • HDR, 4K questions

    Quote from ivobo

    Yes. The TV is Philips 4K Android TV and with Kodi installed on it the same file plays just fine. Only the Rpi4 has problem.

    Please provide a debug log, the output of modetest | pastebinit while playing a HDR file and mediainfo output of the file (mediainfo is available in the multimedia tools addon).

    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

  • HDR, 4K questions

    Quote from ivobo

    Today I found out that my Rpi4 can play 4k hdr10 file, but with washed-out colors... while my Huavei laptop, Ryzen 5 3500u, running Kubuntu, can play the same file just perfect (with vlc and Kodi), with HW acceleration and very nice colors? Why is that? why Rpi4 can not do it?

    Does your TV support HDR and BT.2020?

    If not that's expected as the RPi can't tonemap HDR videos to SDR which vlc on your laptop probably does.

  • Why no Kodi 19.5

    Quote from chewitt

    So i'm telling you (as a Team Kodi person) that the original intention was always to make the K19.5 release immediately before K20. The dates for K19.5 on GitHub will be pushed back as/when someone remembers to move them until roughly that happens.

    Sorry for the misinformation and thanks a lot for correcting me - seems I remembered wrong.

    K19.5 milestone due dates were rather chaotic though and it would have been better to set no date at all if they didn't have one. That really gave the impression 19.5 should be out in summer 2022...
