[android-porting] evs app automotive crash SIGABORT

[ABOU ZID Ahmed]

Hello,

I integrated an Android Automotive on the Hikey960 Board based on Android P.
I'm getting some troubles with the evs_app.
I have a webcam connected to USB port, the device is well recognized and
create a /dev/video0 driver.
The EVS Hal is running as service.
Then, I start the EVS Sample Driver in one terminal and in an other I start
evs_app.

I see a new surface constructed but then directly a crash occurs. Here is
the full logcat.

I identified the problem
https://android.googlesource.com/platform/packages/services/Car/+/master/evs/sampleDriver/EvsV4lCamera.cpp#499
<https://www.google.com/url?q=https://android.googlesource.com/platform/packages/services/Car/%2B/master/evs/sampleDriver/EvsV4lCamera.cpp%23499&sa=D&usg=AFQjCNH6uEQuL3jN5c9TGkPPx2ZWmGelqw>
This function transfers the video image into the output buffer, and makes
any needed format conversion along the way.
mFillBufferFromVideo is a function’s pointer: that can point in one of
these function.

depending of the pixel format of the driver :

Could you please help me fixing this and make it work ?

Thank you very much.
