I have posted in milaq's thread that I've installed the 0306 update. The camera is working but ...

1. As Dorregaray posted above, "please provide the logcat from taking picture."

2. It's strange you observe the full launch of the native camera app. I continue to observe "can't connect to the camera" for the native cam app.

In Settings > Apps >Camera, what version number to you observe? Mine is:
"com.netco.camera version 1.0"

I've assumed this "native app" is the camera app provided by CyanogenMod in the CM11-3.0kernel build. At least I did not install on my own. Or is it possible the camera app is a custom add-on app by Milaq?

In Settings > Apps >Camera, Cache shows 12.00KB. When I click clear cache button, I observe no response.

Could this article she'd some light onto the camera issues? Specifically the battery issue. http://www.ibtimes.com/google-worki...android-devices-kitkat-qualcomm-chips-1559771

No, we're using older camera api and have no mm-qcamera-daemon. The mm-qcamera-daemon is used for V4L2 version of camera hal. IMHO this is very weird app - it seems to connect to the camera kernel driver at startup and keeps the connection for all the time even you're not using camera. This may lead to some issues similar to the one I have in my camerahal and draining the battery. Fortunately for Touchpad it has been fixed.

Thanks. See attached:

Thanks. It seems that the native_jpeg_encode function failed:

Code:

03-06 16:39:52.313 I/mm-still(  147): jpege_set_destination: invalid outpt buffer
03-06 16:39:52.323 E/QualcommCameraHardware(  147): native_jpeg_encode: jpeg_encoder_encode failed.
03-06 16:39:52.323 E/QualcommCameraHardware(  147): jpeg encoding failed
03-06 16:39:52.323 I/QualcommCameraHardware(  147): Unregister MAIN_IMG

edit: it seems that milaq is using wrong camera blobs.

so if you're able to download the following libs:
https://github.com/TheMuppets/propr...45e59/tenderloin/proprietary/lib/libgemini.so
https://github.com/TheMuppets/propr...045e59/tenderloin/proprietary/lib/libmmipl.so
https://github.com/TheMuppets/propr...45e59/tenderloin/proprietary/lib/libmmjpeg.so
and then upload to the /system/lib on the device replacing the original ones you should have camera taking pictures

Mine is the app that came with the ROM update, so it's 'native' and it's version 2.0.002, Cash is 12.00KB.

I replaced the files in milaq's ROM with the above and now I too get the 'Can't connect to the Camera' error. I would have posted the catalogs but I don't remember how to find them. I know the OP (I think it was him) posted once how to do it but I didn't really pay attention to the post and now I can't find where I saw it.

Works! Thanks.

Make sure you set permissions and reboot.

Thanks. Strange I have an old 'native' camera version. I just uninstalled it and hope the next nightly I flash will install a newer version. And will scan through my various apps directories to see what may be lurking.

It's "catlog". Google Play Store has a free 'Catlog' app that works well.

Will do tomorrow. A kind thanks for the continued support in solving camera issues!

Am I to understand after skimming this thread that at this time any kernel 3.0 CM11 ROM will have the blue tint when recording video and you'll need to move up to kernel 3.4 to remedy this?

Thanks in advance.

No, it works just fine.

@_Dorregaray_, do you still have your HP Touchpad to help with the camerahal on 4.3 kernel/marshmallow?
