building on ppp ee postmarketos

[giorez]

I git clonED https://github.com/kgmt0/megapixels -b linux-megi-6.1 on my PPPee running postmarketos edge, kernel 6.1. I built megapixels with meson/ninja, but when I run the app, I get this error:
Found config file at /usr/local/share/megapixels/config/pine64,pinephone-pro.ini
Adding camera rear from config
Adding camera front from config
(megapixels:5822): Gtk-WARNING **: 16:37:24.509: cannot open display:
Any help?

Try setting the DISPLAY envvar, e.g. export DISPLAY=:0.

thanks, it solved this issue. Unfortunately the building process seems to put the megapixels files in the wrong directory. The files are in the "/usr/local/share/megapixels/" and when I lauch $megapixels i get missing config file error. here are the commands i run:

git clone https://github.com/kgmt0/megapixels -b linux-megi-6.1
cd megapixels
meson build
cd build
ninja
sudo ninja install

If I move the installed files I anyway get following errors:

pmos:~$ megapixels
Found config file at /usr/local/share/megapixels/config/pine64,pinephone-pro.ini

And the application has only a flickering button at the botton of display

Hi @kgmt0,

So I built the latest image of PmOS v22.12 which has kernel 6.1.3 that got the cameras enabled.

However I still can't open the megapixels application:

$ DISPLAY=:0 ./megapixels
Found config file at /usr/local/share/megapixels/config/pine64,pinephone-pro.ini
Adding camera rear from config
Adding camera front from config
MPCamera: VIDIOC_SUBDEV_S_FRAME_INTERVAL error 25, Not a tty
Failed to open /sys/class/leds/white:flash/flash_strobe
Could not find /dev/media* node matching 'rkisp1'
$ uname -a
Linux eagle 6.1.3 #3 SMP Sun Jan 15 00:02:58 UTC 2023 aarch64 Linux

The switches for the cameras on the back of PPP are enabled.

This seems like the DTS is still missing some nodes for the image/video pipeline like IDSP/VDSP to process the photos.

Any idea which patch I'm missing?

@phodina Based on megapixels-list-devices's output, it doesn't look like anything is missing. My guess is that megapixels is somehow failing to enumerate the media devnodes but I'm not sure.

I had this same issue. Removing the fromt cam section from the config solved it; for some reason it's finding my rear but not my front cam in /dev/media.
