[camera] Taking photo with back camera inverts view

I can confirm that it inverts the preview after taking a picture.

It works using the MWC demo build.
But is broken in the build #36 (which is the oldest one I found)

On the Nexus 10, there is a crash on the android side.
When the camera backend gets restarted in that case (as workaround) the preview texture transformation matrix (set on android side) is flipped in Y direction.

After the restart, logcat shows the following

E/SurfaceTexture( 1352): [unnamed-774-1] updateTexImage: error binding external texture image 0x83c35c (slot 2): 0x502

That's an interesting find, I do recall Jim making a fix to restart the whole thing as a workaround because of this crash now that you mention this.

The crash is causes by a call to "releaseRecordingFrame()".
For the Nexus 10 in the the hardware/samsung_slsi/exynos5, the libcamera2 is used. Not the libcamera.
Android 4.2 was released with a new Camera Hardware Abstraction Layer (HAL) Camera 2.0.

The new Camera 2.0 API does not have the "releaseRecordingFrame()".

I'm now trying to change the android build to test that ...
