Thanks for the tip! I will do that.

Excellent! Thank you! That info gave me the last puzzle piece! It is working now. Thank you so much for all the help. Below, I am going to try to give full details for anyone else who may run into this.

I found the following command in a stack exchange forum post (https://unix.stackexchange.com/questions/4339…ay-output-ports) that let me list out the video devices: find /sys/devices -name "edid". It gave the following output:

/sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-HDMI-A-1/edid
/sys/devices/platform/soc/d0100000.vpu/drm/card0/card0-Composite-1/edid

So that told me that "Composite-1" is the video device name.

I already knew the resolution for NTSC video over composite is 720x480@60i. Using that didn't work at first, but I remembered this forum post I had seen while researching (RE: Composite Video in LE10 on RPi4) that mentioned you had to use an "e" at the end to force enable it, because composite video doesn't support sensing a connection.

So I looked up how to edit the /flash/extlinux/extlinux.conf file, as you recommended. I found the details here:

https://wiki.libreelec.tv/configuration/edid#editing-the-extlinux.conf-or-syslinux.cfg

I ran the following command to remout the flash partition as read/write (it is read only by default):

mount -o remount,rw /flash

Then I ran the following command to edit the /flash/extlinux/extlinux.conf file in nano:

nano /flash/extlinux/extlinux.conf

Then you need to add the following to the end of the "APPEND" line video=Composite-1:720x480@60ie. In my file it was the bottom line. You don't need a comma separator, just a space. My /flash/extlinux/extlinux.conf file now looks like this:

LABEL LibreELEC
LINUX /KERNEL
FDT /meson-gxl-s905x-libretech-cc.dtb
APPEND boot=LABEL=LIBREELEC disk=LABEL=STORAGE quiet systemd.debug_shell=ttyAML0 console=ttyAML0,115200n8 console=tty0 video=Composite-1:720x480@60ie

Then I just save the file and rebooted. Now the composite video output it working!

Once again chewitt , thank you so much for your help! I don't think I would have figured that one out on my own. Your help is very much appreciated!

Thank you for your continued time and assistance!

Thank you for explaining that. I figured there was something I was misunderstanding.

Thank you again for your assistance!

I just got a Libre Computer AML-S905X-CC, Le Potato (https://libre.computer/products/aml-s905x-cc/). I am planning to use it as a video player/HTPC for the kids to use in the car. Our car only has composite (RCA) audio/video inputs, which is part of the reason I chose Le Potato, as it supports native composite output. I would like to avoid using an HDMI to composite adapter if possible.

I decided to install LibreELEC for this project. I downloaded the latest nightly from the link in this document: https://test.libreelec.tv/11.0/Amlogic/lepotato/. I downloaded the “LibreELEC-AMLGX.arm-11.0-nightly-20221223-a0bd737-lepotato.img” image and imaged it to an SD card using the LibreELEC card imager.

Everything booted up and seems to work fine with HDMI video output. However, when I connect the composite video plug instead and boot up, I do get video and audio, but the Kodi interface never shows up. All I see from the video output is the LibreELEC splash screen, with the build number up in the top left corner. Interestingly, I do think Kodi is actually loading up because I can hear the audio output. For example, if I start pressing arrow keys on my keyboard, I here the Kodi interface navigation sounds. For some reason, the interface just won’t show up on the screen.

I have tried searching in your forums and wiki, but have not found information specific to my situation. A lot of the information in the forums seems to revolve around raspberry pi specifically. Some of the info in the wiki seems to be either outdated or not specific to this build of the software. For example, this document (https://wiki.libreelec.tv/configuration/config_txt) says I should be able to find the config.txt file in /flash/config.txt, but when I SSH into it, no such file exists there.

Also, I am generally a Linux novice, so it is entirely possible that I am just not understanding something correctly.

If you could provide any guidance, it would be most appreciated! Please let me know if you have any additional questions or need more information. Thank you for your time!
