I am using embox on stm32f769i discovery board.I was trying to access ip camera (model :CP-UNC-TA21L5 )stream and take a image of it and store it in the board,but as I notice embox-opencv's videoio was not enabled.I enabled videoio in opencv makefile then tried to get stream using  videocapture api which is defined in opencv,but it throws out an error and resets.
I have mentioned the error below.

OpenCV(4.0.1) Error: Assertion failed (pthread_key_create(&tlsKey, NULL) == 0) in TlsAbstraction, file /home/akshay/Documents/embox/build/extb2
terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.0.1) /home/kiran/Documents/embox/build/extbld/third_party/lib/opencv/opencv-4.0.1/modules/core/src/system.cpp:1302: error'
Kindly let me know whether accessing a video of an ip camera is supported in embox.

Thanks and regards,

Anton Bondarev

Hi, Akshay.

Is it a runtime error message?

Look like you should use 'embox.kernel.thread.thread_local_heap' instead of 'kernel.thread.thread_local_none'. Try to switch it in mods.conf

Kindly let me know whether accessing a video of an ip camera is supported in embox.
Now as I know Embox has no cameras support in Embox, but it is interesting for us

P.S. Akshay, could you please subscribe to this mail list if you want to send any letter to it.

Regards, Anton

Hi - I'm new to this. I'm looking to see if there's anyone that has experience in using opencv with an stm32 board. I'm attempting to run a facial recognition project on this stm32 board for a class. Thank you for any help.
