Composite Video in LE10 on RPi4

Is it possible to use custom/random video resolutions?

Quote from HiassofT

Getting composite video on RPi4 is currenntly a bit messy as composite has to be expicitly enabled in the kms driver, too (on RPi0-3 it's enabled by default in kms and there's an option to disable it).

This means you either have to modify distroconfig.txt (which isn't great as it will be replaced on every upgrade) or copy the contents of distroconfig.txt to config.txt and disable the distroconfig.txt include (which isn't great either as you may miss important changes to distroconfig.txt on upgrades).

That being said you need to make 3 changes to get composite out on LE 10.0.1:

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

Code

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

enable tvout in config.txt

Code

enable_tvout=1

set your desired mode in cmdline.txt (on the same line after "quiet"). eg for PAL:

Code

video=Composite-1:720x576@50ie

or for NTSC:

Code

video=Composite-1:720x480@60ie

Note the "e" at the end, it's important, if you omit this kodi won't detect the output (as connector status is "unknown" because composite doesn't have hotplug detect, with "e" in the mode it's forced to "on").

so long,

Hias

emphasis should be placed "(on the same line after "quiet")." i.e. do not copy paste it onto a new line or else Kodi will not show after libreelec boots up.
