hi all，now i test jpeg enc and dec ，i found that if i create the encoder or decoder use the createJPEGEncoder or the createJPEGDecoder ,then if i use the opencv to encode at the same time ,then it will have the following error:
Thread 6 “test_video_enco” received signal SIGSEGV, Segmentation fault.

so whether that have some conflict with the opencv
