Qcamera

[Yaima President]

Ihave searched the web including the XDA Developers site and some have reported that unstalling the Yahoo Messenger Video/Voice Plugin solved their problem. I have done this and the issue persists. I have even uninstalled the apps I installed around the time this became an issue to no avail.

KLRSKIR, let's save the battery life on your device. Have you downloaded any 3rd party applications that utilize the camera feature on your device? Some application software can affect the performance of your device. I recommend that you uninstall applications that access your camera feature. Keep us posted.

Has the problem returned?. I have the same issue and I have uninstalled the plugin and all 3rd party apps. The problem clears up after I clear the cache and rebbot only to reappear at some point. Interestingly enough I have the problem after extended periods of inactivity such as ovenight charging without opening any app!!

I don't even have Yahoo Messanger on my phone and if I do, cannot locate it anywhere, this is very frustrating. How do you locate and uninstall? Install a 3rd party to uninstall, that sounds ridiculous, why can't you remove files from an OS without the addition of applications?

@I-R-V,

Let's send out the search party and find Yahoo Messenger on your phone.

What phone do you have? If you have the Note 3 you can follow these steps to uninstall 3rd party apps. Please keep in mind that you cannot uninstall apps that were preloaded on the device.

Are you also having issues with the battery? Please provide details regarding your concerns so I may better assist you.

I, too, just started experiencing battery drain. I noticed the mm-qcamera-daemon draining 86% of my battery. I do not have Yahoo Messenger. I did follow the uninstalled applications most people posted on the web. Deleted or at least tried to uninstalled all google stuff but it won't let me. My guess is they are factory installed. I also trashed my camera icon off the home screen. That did not help. It thought it was the Flashlight but I uninstalled that, too. I have a Note 3. Powered down twice.

I had the same problem. I called Verizon and they sent me a new phone and also request a new battery. There is a power save mode and select auto bright on the screen hold the home button down and turn off all the apps that you want off. Something about the first wave of updates messed mine up after the new phone and battery and the NEW update my problem was solved. Hope that helps.

This is happening to me. My phone app went black and now my battery is draining very quickly. mm-qcamera-daemon is listed as draining my battery. My battery drained in two hours from full charge today and my phone got really hot! There is a lot of information here on this topic. It seems pretty widespread....

as i tracked down the problem is with gstreamer v4l2 drivers as qcamera is using it and standalone gsteramer doesent work either with my arducams

the bug appears to have recently been fixed with 1.22.1 build at

has anybody here countered this problem and knows how to fix?

or can you give me links with instructions how to build gstreamer from source and install the libraries since the latest gstreamer version i get with apt-get is 1.18

I will now try to compile and install the bad plugin package with -Dbad=enabled. But im not sure if it will fix this because it seems to me that when i install sudo apt-get install qtmultimedia5-dev this will automatically install and try to use the 1.18 gstreamer - this is what i conclude from that error message.

Tx, but what i will need to do is to take this QT C++ code from qcam\apps\src - libcamera/libcamera.git - libcamera official repository and put into my QT C++ app. Just a small problem is that if i build libcamera from source i do it with meson, but my application uses qmake so combining the two codebases might not be a trivial task.

So I just found out that the fix in gstreamer 1.22.1 that makes camera work with Qt is just one line in gstreamer source code. What i will try next is to check out gstreamer 1.18 source code, put that fix in it, compile and install since my qt app was able to reqonize camera when gstreamer 1.18 was installed. This is the fix if im not mistaken: -/commit/67df248270491116af6099bf3bec5c740dfe3042

This fix didnt work out. It was either the qt plugin didnt use it, this fix wasnt enough. Theres a lot of files had changed from 1.18.6 to 1.22.1 but i think i succeeded carrying that fix over. This is what i did:

ok, the qcam with your script was installed to /usr/bin/qcam and it displays video. It works but the qcam i compile from source does not work with my camera. I tried both 0.0.4 and 0.0.1 versions. Can you tell me why?

I managed to convert libcamera simple-cam meson example to QT project. I used chatgpt to convert meson.build to .pro file. For those in the future who are struggling integrating libcamera to qt i have uploaded the project to GitHub - henrihallik/simple-cam-qt: libcamera simple-cam QT project conversion.

Also chatgpt proved vital working through various linker errors that occured. So if u need more help , just ask openais chatgpt.

so the simple-cam-qt was too difficult to figure out how to modify to capture an image with set resoluton. So I converted libcameras qcam project to qt project that already has image capture functionality in it.

U can get it here if u want to:
