HiassofT Thank you for looking into this.

Da Flex I tested just to confirm and I had to uncomment dtparam=audio=on and audio_pwm_mode=1 in order for composite to work on Stable version LibreELEC-RPi4.arm-11.0.3.img.gz for Pi4

Quote from Da Flex

Code

# uncomment to enable analog audio output
dtparam=audio=on
audio_pwm_mode=1

Not sure if you really need this, because "composite video" already has audio included. I'm I missing something?

But it says to uncomment to enable analog audio out.

I tried again with a clean install using LibreELEC-RPi4.aarch64-12.0-nightly-20231219-865d980.img on a Pi 4 4GB

Help with composite output for LibreELEC-RPi4.aarch64-12.0-nightly-20231217-1833aee

I'm using Microsoft Zune 3.5mm composite cable. Used it before without issues.

Hardware: Rasberry Pi 4 4GB RAM (No overclocking)

This is what I have on cmdline.txt per instructions found in config.txt

boot=UUID=1712-0016 disk=UUID=394a24c2-c88a-4566-8f31-e98cf8d0886a quiet console=tty0 video=Composite-1:720x480@60ie

This is what I have in config.txt

Pi 2 builds are for Pi 3.

Thank you for this information.

Pi 2 builds are for Pi 3.

I installed the Pi 4 version from Raspberry imager and somehow it worked. What gives?

Nightly build only shows Pi 2, 4 and 5 but not Pi 3 builds for download.

Raspberry Pi imager ALSO shows only Pi 4 even when I select Pi 3 as my device.

What's the maximum gpu_mem= allowed for 4K playback on Pi4 4GB running 11.0.3 ?

It plays 4K but crashes when I change to different chapters of a movie.

This is already supported and if you do a clean installation of LE11 config.txt will contain the instructions how to enable it

so long,

Hiassoft,

I highly suggest adding the following changes:

1. It should be noted in the instructions that adding video=Composite-1:720x480@60ie comes after "quiet" in the same line. (

cmdline.txt)

2. Calibration instructions should be included in the config.txt as an additional step to take after rebooting.

3. Instructions says to "Use distroconfig-composite.txt instead of distroconfig.txt to enable" but inside of both distro-composite and distroconfig.txt it is noted not to edit the file which makes the process confusing. I didn't edit neither but I did remove the hash from the line #include distroconfig-composite.txt found in config.txt (I hope that's what I was supposed to do)

I've spent a months trying to figure this out. Not all of us are geniuses and not everything seems obvious for everyone. I hope my suggestions are implemented in some way. Thank you for your work.

Quote from chewitt

Kodi has a calibration function that you can use to (re)align the edges with the screen.

1. Where can I find those options?

2. Why the instructions say 720x480 instead of the correct 640x480?

Thank you in advance

Hi HiassofT,

Thank you for taking the time to respond. It is only partially working. The interface gets cutoff on the left and right side.

For 4:3 it should be 640x480 and not 720x480

Please review the image I included with my response. I would greatly appreciate your help.

Thank you

I hope this request finds you in high spirits. As a long-time user and supporter of LibreELEC, I have always admired your commitment to providing an accessible and open-source media center solution. Your dedication to serving the community has played a significant role in empowering individuals across the globe to enjoy their media content in a user-friendly manner.

With that in mind, I would like to draw your attention to an important but often overlooked aspect of media consumption – the continued use of CRT (Cathode Ray Tube) televisions. Although it might seem that flat-screen televisions have completely taken over, a considerable number of users still rely on CRT TVs. This is especially true in developing countries where access to newer technology is limited or economically unfeasible for many people.

To cater to this audience, I humbly implore the LibreELEC team to consider adding composite out support to your software, specifically for CRT TV users. By doing so, you would be reaching out to a niche but significant portion of the global community, ensuring that they too can benefit from the remarkable features that LibreELEC offers.

The inclusion of composite out support would not only enhance the user experience for CRT TV users, but it would also showcase LibreELEC's commitment to inclusivity and adaptability. This feature would allow users with older televisions to access and enjoy their media content with ease, bridging the technological gap for those unable to afford newer devices.

In conclusion, I sincerely hope that you will take this request into consideration and work towards implementing composite out support for CRT TV users. By doing so, you will further solidify LibreELEC's position as a versatile and accessible media center solution for users across the globe, regardless of their technological constraints.

Thank you for your time and attention to this matter. I eagerly await your response and hope that you will choose to support this initiative.

How can I run 640x480 NTSC 4:3 aspect ratio on composite to consumer CRT with RPi3 B+ running LibrecELEC 10.0.3 ?

I doing the following below but is not true 4:3 640x480 NTSC.

"composite=1" to the kms dtoverlay in distroconfig.txt

dtoverlay=vc4-kms-v3d,cma-512,composite=1

Enable tvout in config.txt

enable_tvout=1

Set mode in cmdline.txt (on the same line after "quiet"). eg for NTSC:

video=Composite-1:720x480@60ie

The results is a squished image that makes eveything look tall and vertically long. It is not true 4:3 aspect ratio.

I've looked everywhere without sauccess. I would appreciate some help.
