  • Legacy v9.2 (LTS) builds for Amlogic S805/S8X2, S905/S912 and all WeTek boxes

    jim_p As per the wiki, AMLGX images are for 64-bit hardware (S905 and up) and AMLMX is for Meson 8 (S802/S805/S182) although S812 is not functioning. There hasn't been much upstream work done on the Meson 8 codebase in the last year as the sole developer (Martin B) has been keeping himself busy with other things.

    The last AMLMX pre-pre-Alpha test image I created was in Feb '22: https://chewitt.libreelec.tv/testing/ - It did boot on an Odroid C1 but I can't speak for anything else.

  • rate-limiting my downloads of img files

    LE provides all core downloads via 3rd party mirror servers: https://releases.libreelec.tv/mirrorstats

    It is possible for some users to download direct of our infrastructure, but those downloads are a minority and do not use enough bandwidth to concern or cause expense to the project. So we don't really care if you set rate limits or run at full speed. The other 99.99% of users will be downloading from a mirror; so all the bandwidth consumed is someone else's - donated for free for that purpose.

    Almost all open-source projects do some variant of the same thing (hosting on GitHub, via mirrors, via some major repo, etc.) so while it's nice to be a good netizen, you're probably over-thinking this issue.

  • A95X F3 Amlogic S905W2

    Quote from lafleur

    I'd like to run the latest LibreELEC image that used the vendor GPU drivers. Or is anyone aware of LE9.x images usable for the Radxa Zero ? They seem to have all disappeared in the end.

    LE (or me) has never created an image using vendor GPU drivers for Radxa Zero. We switched to mesa/panfrost before support for the Zero was added upstream.

    frakkin64 I'm not sure that bug would be found in LE images since we aren't using EFI boot code paths in u-boot? - I can see how it would show up with dekstop distros though.

  • LE10 pc restarts instead of sleeping

    Comparisons with another Linux OS (Ubuntu, Fedora, etc.) are relevant - if it works fine there, there's some level of proof that the hardware and firmware combo can play nice with Linux. Proof that it runs great under Windows isn't particularly insightful since a) You'd expect a product built to run Windows to play nice with Windows, b) The Windows power architecture is completely different to Linux.

  • LE10 pc restarts instead of sleeping

    Issues with Shutdown/Restart are normally related to BIOS/firwmare versions (supporting ACPI states correctly) and power/config settings in the BIOS/firmware (what's needed for Windows isn't necessarily what's needed for Linux). And some hardware is just broken and there's not much we can do about it. You might want to start by telling us what hardware you have?

  • Run LibreELEC in virtual machine without real gpu

    The OVA image we spawn from Generic images is designed for vmware to make booting in a Desktop environment simple, and with the sole purpose of supporting development of project GUI items like the settings add-on. Any other kind of platform or use-case is deliberately "not officially supported" to keep project maintenance simple. Over time the number of other environments it might work in has probably grown, but we do not test that image much, have no intention to start testing it much, so anything that happens to work is accidental.

    In all cases LE needs to boot with a supported GPU, which is either real hardware mapped for our use, or one of the working virtual GPUs in the kernel. The Generic kernel defconfig is probably missing drivers for whatever GPU that proxmox uses; or the GPU that is there doesn't support the OpenGL video pipeline that Kodi requires.

  • Composite video output on AML-S905X-CC, Le Potato

    Glad that you got it working :)

    If you're only going to be playing SD media I'd suggest that you disable hardware decoding in Kodi playback settings. The upstream decoding drivers are fine with H264 but aren't perfect with older codecs or HEVC. However the S905X chip never runs particularly hot and small filesize media isn't too challenging to software decode, which will avoid hardware decoding glitches.

  • Composite video output on AML-S905X-CC, Le Potato

    Code
    info <general>: Found resolution 1280x720 with 1280x720 @ 50.000000 Hz
debug <general>: CGBMUtils::CreateSurface - created surface with size 1280x720

    Kodi is started and apart from there being only a single resolution ^ available (720p@50) everything looks normal. I guess the head-unit is expecting some other resolution as input? - so you may need to force the CVBS output to something else using kernel boot params.

    e.g. something like "video=TV-1:1920x1080M@60" added to params in /flash/extlinux/extlinux.conf

    NB: I'm not 100% sure of the connector name (TV-1) or what resolutions are possible.

  • Libre Elec freezes with all builds so far on le Potato

    Hardware decoding on a modern kernel codebase requires patched kernel + patched ffmpeg. LE sources are currently as good as it gets:

    FFmpeg work for RPI. Contribute to jc-kynesim/rpi-ffmpeg development by creating an account on GitHub.

    The manjaro folks are tracking patches fairly well to result in a useable 'current' distro. Performance and feature completeness on the vendor kernel (used by CE) is better, but compatibility between old vendor kernels and the rest of a modern distro codebase can be a challenge.

    The main negative I've seen in the LE/AMLGX image with LePotato is 100-BaseT Ethernet (common to all S905X boards). If trying to play large ISO rips Kodi often warns about slow sources etc. - S912 devices are normally better since most have Gigabit NICs.

    NB: CE is run as a separate project so report any issue to their forums, we don't track their images at all.

  • Libre Elec freezes with all builds so far on le Potato

    Two suggestions:

    a) Drop the kernel.img and SYSTEM files from dtech images into /storage/.update/ and reboot to udpate to 9.2.8 which might behave better than Ye Olde 9.0.2 image now.

    b) Have a play with https://chewitt.libreelec.tv/testing/LibreE…lepotato.img.gz which is using K20rc1 and modern uboot and Linux. Hardware decoding isn't perfect and there are some features on the long-term to-do list still, but as long as your media requirements aren't too challenging it's quite usable.

  • Composite video output on AML-S905X-CC, Le Potato

    Code
    echo "<advancedsettings version=\"1.0\">" > /storage/.kodi/userdata/advancedsettings.xml
echo "  <loglevel hide=\"false\">1</loglevel>" >> /storage/.kodi/userdata/advancedsettings.xml
echo "</advancedsettings>" >> /storage/.kodi/userdata/advancedsettings.xml
reboot
cat /storage/.kodi/temp/kodi.log | paste

    ^ The advancedsettings.xml file content puts Kodi into debug mode. Then share the URL so we can see what DRM properties Kodi can see?

  • LE11 nightly 2022-12-28 - HDMI 2.0b: no 4K Video, no HD Audio

    ^ According to this, there are two streams: #0 which is 4K, and #1 which is 1080p. The next lines are confusing as they appear to show stream 0 being discarded (as it contains Dolby Vision) and then the last line shows it opening stream 0. Regardless, the root issue here is no support for Dolby Vision. This is a known restriction; there is no open-source implementation for Dolby Vision. Kodi can play DV media on Android devices that have DV licensed support built-in to their software, and on a small number of Linux devices that use (Android oriented) ARM vendor kernel/ffmpeg sources have have DV support. Nothing exists for Intel so there is no playable video stream; hence what you see.
