Camera - black viewfinder...
asked 2014-04-08 23:11:33 +0300
In the last few days I used camera a lot and sometimes the viewfinder became black. Already tried : killall jolla-camera systemctl-user restart booster-silica-qt5.service restart of lipstik.service
Nothing helps to restore camera to work again except reboot Anybody know which process we can restart to get camera back without reboot ? Thanks
P.S. Same question asked on TMO: http://talk.maemo.org/showthread.php?t=92987

I started to get black viewfinder on my jolla C...
I don't really know when it started, now I'm on snowboard vacation and when wanted to take some pictures, I noticed about black viewfinder on main camera. On front camera it sometimes work and sometimes also black.
I didn't install any new things, but I did 2 new things:
1. I changed battery, that work perfect.
2. I now in French alpes with with roaming from my Israeli sim card. The connection dropped many times 2-3-4G, sometimes lost connection and reconnect again. Sometimes I feel a hot spot around the camera lens.
That all..
Already tried:
1. killall -KILL mm-qcamera-daemon = not help
2. Reinstalling camera app = not help
3. Removing camera app + reboot + reinstalling camera app = not help
4. Disabling all patches = not help
5. Lipstick restart = not help
6. Reboot/shutdown - sometimes it started to work, but after some minutes I get the black viewfinder again. Today even reboot/shutdown get the same result from the beginning (black viewfinder) = not help
7. Tried to play with dconf commands related to jolla-camera, but didn't find something that I can change for fixing this problem. Also reset not help...
8. CSD tools camera tests - sometimes pass for both cameras, sometimes only for front camera..
9. Tried to install Camera Plus from openrepos, but for some reasons it not starts at all.
10. I also tried some different android cameras and all of them identified only front camera.
Any other ideas for fix ?
Thanks.

After system update (2.1.0.10) the viewfinder started to work, but after some time I've got again black viewfinder...
Unapplied all patches, reverted to v2.1.0.9 and updated again to v2.1.0.10 = not helped... Still black viewfinder... :(
Dont know if this helps, but had similar problem earlier, caused by Ultimate Codec Pack from warehouse. There's thread that helped few. https://together.jolla.com/question/22485/bug-camera-stopped-working-after-1038-upgrade/#22532
kaari ( 2014-04-08 23:17:58 +0300 )editThis bug started to appear only after last system update... Never had it before.. MSameer suggest to kill one process, I will test it the next time when it happens.
Schturman ( 2014-04-09 00:07:34 +0300 )editYes, it seems to be different problem. Especially if you don't have installed any codec or libraries from warehouse.
kaari ( 2014-04-09 00:16:16 +0300 )editMaybe yes, maybe no... I have this codecs, installed many time ago... And of the time not used... Also like I said, the camera problem started after system updated... P.S. I'll try to reinstall this codecs too later, after trying of KILL command. Thanks for answer.
Schturman ( 2014-04-09 01:06:51 +0300 )editThere is at least one known, reproducible bug (or 'feature') which I have reported in my stability findings post. start camera and immediately swipe down to close it before it is properly initialised, and after few tries you have black viewfinder not even grid, but you see icons and menus are functional.
So maybe avoiding swipe down to close when camera app is on something, could help you to avoid the situation until we get proper fix.
