The new source looks good as there is a change in the camera files I think (Kernel/drivers/media/video/exynos)


Code:

I have attached the new kernel files (above) if you already have the previous LL source code. Just copy it and paste it in your kernel files ( I copied them using --parents so drag and drop devs)

Hope new source will solve our little problems, lets wait for devs to work on it :)

EDIT: I have a question about lines in @Safarend 's post. It says driver->mali400 but i don't think this is our gpu model? Mali T628 and Mali400 are same or not?

Not the same. I compiled the source code using the new kernel but I didn't notice any change. All bugs still exists.

@djmax81 when will we get the camera fix ? :/
Is there any ETA ?
If not then we have to wait for another long time I guess

You just pointed out a bug EVERYONE knows about, and now you're asking for an ETA even when the dev asked not to do so. You could help this community by: A)- Fixing a bug or B)- Not posting useless stuff and waiting like everyone else. I believe option B would be good in your case.

Quick Advice

We understand the love for CyanogenMod that lives among us and many others, we also understand the urge people have for the need to use CM12 on their beloved SM-N900. But what everyone needs to understand is that development of a Stable ROM is work that requires peace of mind and pure dedication to reach the goals required. The developers @flashka07 and @djmax81 have provided the dedication to bring us the ROM, so let us in turn provide them with the Peace of Mind to allow them to work on the ROM. We should also understand that the developers also have different activities to handle and daily lives to live, so let us not treat them as if developing this ROM is their full time job.

So, before posting and asking questions like:
  • What is the ETA
  • When is the Camera fix coming?
Please first read quickly or skim through the thread and see what questions have already been asked and answered to. Instead of posting repeating questions, lets post helpful information that may assist the developers to reach our mutual goal as soon as possible. This should be taken into consideration especially by the Newcomers to this Thread.

FYI: Just saying, but please take it seriously.

Guys, i found something interesting about camera. Actually i dont know if it means somethi g but just wanted to share :) While listening to music, if you try to open an app which wants to use camera(snapchat,instagram,etc.) Music skips itself. This happened to me every single time. Maybe this issue has something in common with our camera problem.

Hope you all having a good day:)

Hey Devs,
I'm trying to fix the camera :silly: but it didnt work at all. Same result every time.
Tried to copy settings from i9500, klimtwifi, basicly any device that has exynos54** but no luck. I'm trying all possible combination.
I know you are busy but a hint where to look can be helpful.

The files that I cannot touch because they are complicated to me for now are the following:
  • rootdir/
  • sepolicy/
Are they worth looking into because I need to study them (bootloop causer)?
Why do we have in sepolicy/file_contexts
Code: 
/dev/v4l-subdev[0-9]*   u:object_r:video_device:s0
instead of the following which match the stock lollipop? (I guess)
Code: 
/dev/v4l-subdev[0-9]*   u:object_r:camera_device:s0
Thanks guys

It is not important now, since selinux is disabled in kernel. I patched camera wrapper in January to make library linkage possible, but now we have a runtime fault because of gralloc module may be.
RaymanFX's script made a thing (that creates a CameraID.txt file), but it is not enough.

Sorry to bother you guys again.

I played a lot with gralloc but always end up with bootloop :crying:

So I tried to fix one error by a time and I hate the omx error so I changed the media_codecs.xml file and similar files media_*.xml and the omx errors are gone and the camera are giving more information like setPreviewSize with actual sizes instead of zeros check log for more dets.

But there are only one error which kills the mediaserver and I don't know how to fix it.

Please devs check the lines in logcat attached:
553:
Code: 
E/ExynosCameraHWImpl( 2343): invalid gralloc handle (at 0xb1d11040)
--------- beginning of crash
F/libc    ( 2343): Fatal signal 11 (SIGSEGV), code 1, fault addr 0xc in tid 4085 (CameraStartThre)

I/DEBUG   ( 2338):     #06 pc 00011f93  /system/lib/libc.so (__start_thread+6)

It seems like thread problem, is this issue related to what @crpalmer said
On at least the current Exynos based devices, the vendor's HAL
appears to be unable to handle the threaded startup
Click to expand...
Click to collapse
Do I have to add this to the overlay Camera2 res ?
<bool name="enableThreadedCameraStartup">false</bool>
If I created an app that takes a picture without using threads is it worth a try?
Any hint will help as I'm running out of time (Doing my thesis)
Thanks for the help guys

    Good News


    I successfully increased/decreased the Incoming voice volume while in call (NO REBOOT :D ).

    Since it is a hack it will take sometime to integrate it to the call application (I'm using adb for now).
    Maybe 2-4 days and I will build a fresh one with the hack/fix.
