What's the full 5.10 version you had that mode with? The mode name is normally generated by the DRM core code through `drm_mode_set_name` - https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/drm_modes.c#L1268. That will never add "(scaled)"...

I'd missed that PR, or decided it needed further review and never came back to it. It's not the right answer though - if you want a 720x480 framebuffer on...

The firmware does process timestamps under a number of situations. The ones that immediately come to mind are: - Video decode has some code to fix up timestamps when we're...

popcornmix knows more about the deinterlacing use case as it gets used in Kodi / Libreelec. The negative value bit is https://github.com/raspberrypi/linux/blob/rpi-6.6.y/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c#L2672-L2686 when -1 is passed as a parameter to...

That conversion was added before the G_PARM/S_PARM ioctls were added in https://github.com/raspberrypi/linux/commit/e6c4cec054bf9b32f5292cfc5edef9856dabaa03. The encoder rate control algorithm will work with either timestamps or a predefined framerate. Based on a quick...

> PS: a bit off-topic, but i have off-by-one on fluster decoder testing (vs the software decoder), is there a config setting i can use to fix this? Off-by-one on...

I'm not intending on updating anything here, but will adapt to whatever gets merged upstream as and when it happens. FWIW I'd suggest renaming it to bcm2835-m2m when you next...

If the timings result in timeouts when specified in config.txt then I'd read that as the timings being invalid. What are these magic timing values that you're using? If any...

If you wish to ignore DRM/KMS then feel free. Remove ```dtoverlay=vc4-fkms-v3d``` from /boot/config.txt, and you have a fighting chance that vcgencmd hdmi_timings will work again. You have then also removed...

modetest is a test app only. Did you look at the underlying library? ```drmModeAttachMode``` - https://cgit.freedesktop.org/mesa/drm/tree/xf86drmMode.h#n475 ``` /** * Attaches the given mode to an connector. */ extern int drmModeAttachMode(int...
