[PAC Q&A] AlaskaLinuxUser:
EDIT: This has been resolved. Updating vendor blobs and device trees fixed the issue. Thank you for your time.

Greetings Developers,

I would really appreciate some help. By God's grace, in the T-Mobile S4 development thread http://xdaforums.com/galaxy-s4-tmobile/development/rom-pac-rom-mm-t3400111 , I have put together several Marshmallow Roms, namely PAC Rom and AOKP MM, that have the same problem. The camera works to take pictures, but cannot record video. It "appears" to be recording in the built in camera app, but does not actually save the recording. If I use another app, such as OpenCamera, it stops the recording as soon as I try to start. I am relatively new to development, and any help would be greatly appreciated, as well as fully recognized and credited.

Below is the logcat errors/fails when using the CM camera app, and the OpenCamer app. I just really want to get this fixed for the people who are using the roms. I hate to sell them short because I've made some sort of error.

In my inexperienced opinion, this appears to be an audio problem. I have compared the mediarecorder.cpp and similar files between CM13 and my roms, and they are identical. I was wondering if it might be vendor blobs, so I borrowed them from Beanstalk (where the camera video recorder function works), but that did not work either.

I am pretty sure that it is not the app, because using any video recording app fails to actually record the video.

Here are the fails from the logcat. I am only focusing on the errors, stops, or fails.

Using the built in Camera app:

Using the OpenCamera App for comparison:

So, the errors or fails that are the same are these:
ACDB-LOADER: Error: ACDB EC_REF_RX returned = -8
MediaRecorder: stop failed: -1007

These are both audio errors. It appears that the audio is creating an error, so the video will not save. Unless someone out there knows better (be sure to correct me, I'm still learning). So I will be looking at MediaRecorder and ACDB-LOADER and audio problems.

Once again, any assistance would be greatly appreciated! Thanks!
