Hi: I found some bugs about nvjpeg encoder; when I init nvjpeg and use is in one thread, it seems fine; but when I init nvjpeg in main thread, and use it in other 4 threads, the nvjpegEncodeImage returns NVJPEG_STATUS_EXECUTION_FAILED my cuda version is 10.2; driver version is 440; PS :image, I know this , I create encode state in every child threads;
