~martijnbraam/Megapixels#37: megapixels 0.13.1-2 crashing with an endless loop

Hi,

at first, let me thank you, as beeing the only one working on this. I'm glad that someone stood up and tried it.

0.13.1-2 (Fedora 34 Rawhide build) for Pinephones is crashing in loops:

Dez 17 18:21:37 fedorapine org.postmarketos.Megapixels.desktop[86481]: MPCamera: VIDIOC_DQBUF error 22, Das Argument ist ungültig" "argument invalid" Dez 17 18:25:00 fedorapine systemd-journald[152]: [🡕] Suppressed342006 messages from user@1000.service

before it got into an endless loop, I used shutter [Auto -> 75] and played with ISO a bit.

also a camera switch reproduces the issue above.

I encountered the following additional problems:

the color / saturation / lightness of the images is next to not there , all images look greyish. I trust you, if you answere: the chip is crap.
the strings "iso" "shutter" do not scale with the image, they are WAY to small on a high dpi screen as used with Gnome, instead of phosh.
the functionality on these two options need improovement: "opening iso" "closing iso" "opening shutter" ... instead of switching between states isn't very useful, but quick to change.
opening directory with pictures => does not work
prefs changes are not remembered

best regards, Marius Schwarz

The VIDIOC_DQBUF error happens if Megapixels is re-launched but the old process isn't killed yet because the postprocessor is running in the background.

Preferences aren't implemented yet.

The sensor isn't great

Hi,

for your information:

Problem:

As soon as you hit the "take picture"-button, programm freezes and logs memory errors until "killall -9 megapixels" hit.
