Rpi5 and waveshare display

[mcpat]

Hi,

I try to get my waveshare display running with latest rasbian on my rpi5. Compilation works and everything is working on HDMI, but I don't have any idea how to get my display working.

Acc. to this https://forums.raspberrypi.com/viewtopi ... 8#p2170664, I have this 'config.txt' parts

Code: Select all

# Enable DRM VC4 V3D driver dtoverlay=vc4-kms-v3d max_framebuffers=2 # waveshare 1.3in - 240x240pixel - SKU19650 dtoverlay=mipi-dbi-spi,speed=32000000 dtparam=compatible=wavesku19650\0panel-mipi-dbi-spi dtparam=write-only,cpha,cpol dtparam=width=240,height=240,width-mm=23,height-mm=23 dtparam=reset-gpio=23,dc-gpio=25,backlight-gpio=24

I can see the console on the display, and if I start cvlc nothing happens on the display. HDMI is working well... I tried really much parameters, but everything fails. MPV is working, but want vlc...

and I get this output with 'drmdevice':

So, how can I show a video on SPI-1 without desktop (wayland) on rpi5?

You need version 4.0 for DRM support. It should work automatically if there are no display servers, but you can also force it with

Code: Select all

vlc -Vdrm

I compiled vlc 4.0 but with same result. I am running Raspian in cli not with desktop.

RetroPie is also working on the display. So the main problem is VLC.

[Rémi Denis-Courmont]

Worked for me last time I tried (on different hardware) though.

If you are sure that this is a VLC problem, patches are welcome.

With the overlay "mipi-dbi-spi"? On Rpi's < 5 I used framebuffer copy and this was working on all displays. But with Rpi5 there are no legacy drivers anymore and fbcp also not possible anymore. With "mipi-dbi-spi" vlc is not running on display. If you can give me a hint were to search I can try to patch vlc and supply the patch too...

[Rémi Denis-Courmont]

The specific error normally means that the DRM driver does not support universal planes (the error comes from libdrm, not VLC). If so, then it's no wonder that KMS won't work. This is a driver issue from my standpoint.

Or what you need is a hardware-specific stuff, not the normal KMS/DRM support that VLC provides.

[mcpat]

I just tried with the original vlc delivered by apt-get

How to tell vlc to use /dev/dri/card2 (it's "SPI-1")?

Eh, what's wrong with the command line help?

[Rémi Denis-Courmont]

That looks like a driver bug.

[mcpat]

sure? because "mpv" is working?!?! Even hw accelerated. Only with vlc I have this problems. Can you tell me where you expect the bug. Is it the "mipi-dbi-spi" with overlay? Or somewhere else?

[Rémi Denis-Courmont]

Maybe mpv has rPI-specific stuff. What do I know.

Point is that it does not look like your DRM driver is usable as a generic DRM output that full screen software could use in absence of X11 or Wayland

[mcpat]

"Fun" fact. Everything above is when I try in a ssh session, I attached a keyboard and started clvc and the video is shown on the display:

I used all for me known parameters, but cvlc doesn't respect the aspect ratio..

When I start mpv without any paramter with the attached keyboard, the aspect ratio is ok (mpv also works via ssh session!):
