I don't think you need to force video= in cmdline.txt, but I think enabling composite output in config.txt results in the same situation where the output is active and because the kernel cannot detect whether something is connected or not there is no fallback. At least, I assume that's the case, as these days I have nothing that accepts composite input to experiment with.
I have tried it. The composite video out is not active without entering video= in cmdline.txt. Thanks anyway.
If you enable composite output or add video=Composite-1:720x576@50ie to cmdline.txt output is forced to that always regardless of whether HDMI has been connected. And because there is no handshaking with the (analogue) composite output, there is no way for the kernel to know nothing is connected and fall back to another display method. There is currently no VNC support for the GBM/V4L2 output we use.
The least-worst idea I can come up with is creating a script add-on that allows you to select/choose between composite or HDMI output in the (add-on) settings GUI and then reboot to initiate the change. That doesn't exist though, and I'm not volunteering
I have already done a shell script that switches cmdline.txt accordingly. I run it by ssh as a workaround. But LE9 was doing it perfectly without needing to connect with ssh before and after connecting to HDMI. I wanted to know if there is a method without forcing composite output like previous one.
I have a rpi3 b+ connected to an HDMI monitor and a composite video projector at different times. First it was running libreelec 9.2.8.
When I connect the HDMI cable and turn the monitor on, the output was on the HDMI monitor. When the HDMI cable is not connected, the output was on the composite video projector. It was doing this only by adding sdtv_mode=2 sdtv_aspect=3 to config.txt.
I have installed a fresh libreelec 12.0.1 to a new sd card. I know that these commands are now obsolete and I did this configuration:
config.txt:
#include distroconfig.txt
include distroconfig-composite.txt
cmdline.txt:
video=Composite-1:720x576@50ie
The composite video out works but when I connect the HDMI cable and turn on the monitor, the screen is blank. It does not fallback to HDMI like the previous version.
Is there anything to do for switching outputs automatically when needed? I don't think it is possible but outputting to both will be OK too.
If not possible, is there any workarounds like a VNC server compatible with libreelec 12? It doesn't have to play video remotely. Only GUI is enough for maintenance, updating etc.
Thank you for your replies. The problem is solved.
Expanding disk capacity is not necessary but /dev/sda2 on /storage was too small and the use was %100.
I have expanded the partition with gparted to maximum and it worked. After expanding, i have noticed that it could even not update the add-ons before. I think previous versions of libreelec was adjusting this automatically. Even though i have resolved my problem, this is still an issue for libreelec 11.0 ova virtual image.
I have downloaded LibreELEC-Generic.x86_64-11.0.0.ova and imported to Vmware Workstation Pro 17.0.1 running under Windows 10 Pro x64.
I have tried to update it to version 11.0.1. I have selected settings - Libreelec - updates - available versions - 11.0.1.
Prompted me "would you like to update libreelec now?". I have selected "Yes"
A brief download window appeared and disappeared in a second. And nothing happened. I have tried several times but the result is the same.
