Graphics, sound and multimedia • Re: Analog video was improved for RPi5 !!!! THANK YOU

You have caught us on the hop, as we are changing the OS version from Linux 6.1 to 6.6 and changing the method for selecting TV standards.

In the older version (this was never documented and will disappear soon), on "cmdline.txt" you should add:

Code:

 drm-rp1-vec.tv_norm=NTSC-J

In the newer version you will use:

Code:

 video=Composite-1:720x480i,tv_mode=NTSC-J

What "NTSC-J" actually means for this driver is: If the mode is 60/30Hz, use NTSC-J (no pedestal), else if the mode is 25/50Hz, use PAL-* (also no pedestal). The command line mode sets up the boot console; once the GUI starts you might have to re-configure the screen resolution there.

Hey, sorry to bother you again, but I don't think I asked about the 240p options?
With older versions of the drivers/kernels, I think there needed to be patches for 240p to work by using video=Composite-1:720x480@60e, and what it would do was to omit every other line so that it would display at 240p as if the image just had scanlines applied.
Today with the latest nightly of LibreELEC, the only way to get 240p is using video=Composite-1:720x240i (yes with the i at the end). But the aspect ratio will be wrong, it seems like things are squished horizontally (im assuming because of course, it's using a 720x240 screen resolution, just squished to the CRT size.)

Is there an extra parameter or something I can put so that the proportion is the same as 480i, just 240p like before? Thank you.
