Hi,
I installed libreelec on my rock64 and works perfectly via hdmi output, but there is no way I can get the image through the 3.5mm jack/av output to my crt tv.
Tried to add in extlinux.config:
video=Composite-1:720x480@60ie
or
video=composite:720x480@60ie cvbsmode=480cvbs cvbscable=1
however nothing works..
There are a lot of instructions for raspberry pi, but nothing for rock64.
Please, could anyone help me with this?
