I also have a Panasonic Plasma, just with TOSLINK instead of electrical S/PDIF. Works fine with my DD / DTS AVR. So I pretty much have the same setup like you. I go RPi HDMI -> TV and TV TOSLINK -> AVR. That should also work for S/PDIF.

Don't bash me please, but isn't S/PDIF the same with TOSLINK?

Indeed this is a TOSLINK (optical) interface and not a coaxial. My tv model is (again IIRC) TX-P50UT50E, dated 2012ish or something.

Connection of my Dell to the TV is made over the non-ARC HDMI. And from TV over toslink to the Yamaha A2.

In your setup are you able to pass-through DD 5.1 data from the RPi to the TV and then to the amp? Whenever I try that I don't get any sound at all on the other end.

AFAIK RPi does nothing special compared to a pc, apart from doing CEC and stuff (which should not be relevant in this case at all). What sort of debugging from SSH could I do to check things up? I really hope that having a similar TV/setup you might be able to help me out.

In the meantime I was looking solutions from aliexpress like these one, but don't know if they do the trick:

Seems like your Panasonic S/PDIF can only deliver stereo. So get an HDMI audio splitter with TOSLINK. It's not too expansive.

Digging around in the tv documentation and making a few tests seems to indicate that the tv s/pdif can also send DD multichannel, albeit from TV stations only (and not from HDMI inputs)

For the record, I did find an oooold addon that did conversion to analog Dolby ProLogic. Unfortunately it's a no go for recent Kodi versions. Would be nice to test though.

As for HDMI splitters: they are tried and tested but IIRC when using them with RPi's there were some issues with the correct transfer of EDID information.

Something like this would probably fit the bill https://www.amazon.co.uk/Cubilux-TOSLIN…600288957&psc=1

That's awesome, especially since it seemed it worked fine on Linux, considering the comments! Pity it's not available for purchase Could you provide any alternatives to that. I live in Greece, so everything from amazon.de (.fr/.it/.es) could be purchased easily.

Funny thing is that I've been searching and searching in aliexpress for example and could not find anything (apart from expensive DACs and HDMI splitters).

Apologies for the somewhat cryptic title. I have a notoriously old setup with a 10 year tv and a beasty 25-year old (!) Yamaha A2 amplifier. Up to some days ago, my needs in the living room were served by a (also old) AMD-based pc that was equipped with an optical output. Setup worked like a charm: video was sent to the Panasonic 50" plasma over HDMI and LE was configured to transcode anything multichannel to 5.1 DD (amp also is 5.1 DTS capable).

The rig went dead and was replaced with a rather cheap Dell optiplex 3050 ultra small form factor thingie, lovable to watch I migrated my LE setup to the new box and everything works perfectly (plus having a UEFI boot).

Problem is that it lacks an optical digital out. Luckily the Panasonic behemoth comes with an S/PDIF out which, at least, makes sure that I can get excellent audio ... albeit in stereo.

Now I'm certain that it is not doable, but have to ask: is there some sort of "magic" that can be used to send multichannel audio to the TV and have the TV just pass the audio to the amp. From what I've tested this does not work. Still, I'm asking just in case it can be made with some sort of tinkering.

For what this is worth, I'm looking into workaround. So far:

* buy some sort of HDMI splitter boxes that take HDMI and output both HDMI and S/PDIF: work but a bit pricey

* was looking into whether small form factor PCI cards with S/PDIF exist, until I found out that the Dell has no room for cards at all

* currently checking whether I can get a USB card that also has S/PDIF without spending a fortune

* will look whether there's some sort of Dolby ProLogic transcoder for Kodi exists: if it does I'll simply transcode everything multichannel to the special stereo signal for ProLogic.

Please free to suggest any inexpensive solutions (if any)

https://wiki.libreelec.tv/configuration/…ration-advanced has instructions (also needing update) on capturing and creating a custom IR config. The bit that needs updating is that the config file format has changed to "toml" .. but if you look at the wiki instructions and compare to the toml files in /usr/lib/udev/rc_keymaps/ the new format is pretty simple to crib.

Mission accomplished on this part just by doing an ir command and creating a one-liner file that referred to an existing rc-6 MCE remote! Thanks Chewitt

I still can't figure out what produces the kernel panic. It still displays beautifully but being a limited device without active cooling it would be nice to lower its load by avoiding doing 24 to 60fps conversions.

For the record the error at boot is:

Failed to execute /init (error -2)

Kernel panic - not syncing: No working init found. Try passing init= option to kernel...

Tried your own EDID just to be certain mine was not at fault.

https://wiki.libreelec.tv/configuration/edid has instructions on configuring an edid.bin file so Kodi sees the TV as always connected. The wiki needs updating to reflect that the Intel instructions apply to all devices using the kernel DRM architecture; including Amlogic (and Allwinner, Rockchip) boards.

Thank you for your edid file, and for your extremely descriptive answer!! Truth is I found a copy in an old backup of mine which I believe is the hacked edid file (was named edid.dat but I think it's the same as a .bin)!

I've followed the instructions but ran into a kernel panic at boot. Looking closer at the (intel) instructions, perhaps there's some minor mistake or the odroid build is a bit different: for example, extlinux.conf actually resides in a subdirectory as /flash/extlinux/extlinux.conf. Not sure if this is an issue. However, and if I understand my Linuxes right, command mv ../edid.cpio /flash/ would leave edid.cpio residing in /flash. The subsequent APPEND to extlinux.conf states that the following should be appended:

initrd=/edid.cpio drm.edid_firmware=edid/edid.bin video=HDMI-A-1:D

Not an expert here, but:

1) should perhaps edid.cpio be at the root directory instead of /flash ?

2) option drm.edid_firmware is looking for an edid directory, is that correct?

3) finally (ok this might be an absolutely stupid question here), there's a smiley at the end of the above mentioned line, is that correct?

I'll get the SD card to mount the vfat partition and play a bit with extlinux.conf to fix things.

As for the remote option: I've been bashing my head REAL hard to find where the heck I have had some sort of configuration of the remote. I have a backup as well as the entire previous SD-based coreelec installation, but there is no file under /storage/.config/rc_keymaps

EDIT: <off topic> For some reason I'm not getting new post notifications, even though I've enabled them. Just a FYI </off topic>

Thanks for taking the time to look into this mate, really appreciate it.

This Samsung tv is ooooold. But has been happily playing 24p material from my (back at the time) PS3 as well as from other sources. Worked perfectly with my old RPi when switched to 24 (using some sort of EDID hack I don't recall, but would happily look into).

On the topic of this jump from coreelec, and OT to this thread, I can't recall how I made a old Creative IR remote work with the C2. I do have a custom remote.xml file over the years, but it does not respond to it so I've installed a keyboard/mouse in the meantime.

Just love the way your work and the LibreELEC team's in general keeps alive these monoliths of hardware

Really glad I'm now using the latest LE image with all the bells and whistles of up-to-date code here

I do have one question though: back in the day, Kodi could (IIRC) auto-switch the display actual refresh rate to "match" the material one. So on a 60Hz tv, when playing 24Hz material, Kodi would switch to 24Hz as well.

Now my old Samsung can definitely play 24Hz material. When doing an OSD display of a23.976 movie and enabling the OSD information display, the system tab shows that the system rendering speed is playing around the refresh rate I've set to the Kodi playback options (60Hz in this case).

I think I used some kind of utility or a hack to hard-insert a 1080@24 refresh rate to my libreelec/coreelec install and that worked. If someone can provide a link / howto, I'd be more than grateful.

Nope, that doesn't do it. There is no /sys/class/amhdmitx/amhdmitx0/disp_cap to be found...

Please read the LE11 release notes, they explain the current state of things fairly clearly. Updates are not supported; clean install only.

Thanks, I read the release notes and read this thread as well. I'm not use I understand correctly something though: is the AMLGX build for C2 providing hardware or software decoding for HEVC and for H.264?

Hello everybody,

I have an odroid C2 which had initially LE installed. At the time I think that coreelec was pushed as a candidate platform for its processor so I migrated to that one. It's been running

CoreELEC (official): 9.2.8 (Amlogic.arm).

Now a couple of months ago, taking a peek at the coreelec information I got the impression that its processor line would not be supported for future kodi upgrades.

Today I was browsing the available LE builds since I have the hardware to upgrade my Intel-based build and taking a peek at the respective Amlogic downloads there seems to be one for Kodi 11!

I'm delighted to see that happen, but I do not understand some things and please accept my apologies in advance for the idiotic questions to follow:

a) is this an experimental build?

b) would I be losing something (performance/features) compared to my current build? IOW, is (for example) some decoding now made in software, whereas in coreelec 9.2.8 was made in hardware?

c) Last but not least, how did you manage to do your magic, whereas it was not possible in the CE builds?

I'd ask for a migrate procedure CE -> LE but it's already covered in Odroid C2 update from CoreELEC to LibreELEC is it possible ?

Thanks in advance for any information provided!

Awesome, will try it asap! Cheers!

The title says it all: I'm trying to figure out how I can see how much traffic is utilized. The link 18 commands to monitor network bandwidth on Linux server – BinaryTides describes various ports/packages/commands on full-blown Linux distros. Any way I can get something like that on my LE/Odroid C2 setup?

For using cacert.pem you must be sure that name or IP address match the cert and server.

Sure, but where exactly (path/file) do I place the pem information of my site?

(bump) Someone?

I'm also in 1080p, with an spdif output to my ac3/dts amp. From the looks of it, I'll take a full backup and then upgrade (to check my entire setup).

If something does not work, I'll just reinstall Krypton and restore...

Asking here because I think there was some Leia pre-release information indicating that VDPAU/VAAPI acceleration would not work on Leia (or that there would be some drop of software support for VDPAU, don't remember here sorry...). I believe it was this bulletin: Development Update – LibreELEC

Most likely I've misinterpreted the information presented there, that is why I'm asking here for advice to upgrade or not. Thanks in advance for any info provided.

Hello all,

got two libreelec installations, one with Krypton and one with Leia (the latter one on an Odroid C2). I've got also a server on the net on which I'm uploading my videos etc. Access to this server is made using its ip address (ie no name is used, although I could use one). On Leia I'm not able to connect to this HTTPS server, even though I'm using the exact same credentials with LE krypton.

Reading further it seems that Leia checks the certificate first. How can I access this site on leia? I've found a couple of posts, one indicating adding |verifypeer=false on the server URL, the other downloading the site's crt file, converting it to pem format and then uploading it to my leia box as ~/.config/cacert.pem. The latter does not seem to work, whereas for the former a couple of posts indicate that it will also not work...

Should cacert be appended to a file elsewhere (for example /usr/share/kodi/system/certs/ ). Or would |verifypeer=false just work?

Before upgrade, when I turn off my tv, the box shuts down, but CEC circuit seems to keep working - after powering back up tv, I see "Odroid C2" device under SmartLink menu and when I choose it, the boards boots up.

Having Odroid C2 (on LE9) I'd be grateful if you could delve some info on how to setup CEC to do the same thing. I'm leaving C2 always on, your approach seems like a much better solution!

Furthermore, I do see that the blue LED has started blinking again, after upgrading today from 8 to 9. Is this a known issue?

EDIT: I see that it is configurable, which is great. I've set it to blink on sd card access, don't know if it could do that thing before.
