I have trouble when opening camera with cv::VideoCapture(gst_str, cv::CAP_GSTREAMER): if I use nvjpegdec In command line gst-launch-1.0 v4l2src device=/dev/video0 io-mode=2 ! image/jpeg,width=1280,height=480 ! nvjpegdec ! xvimagesink It works well, and the fps is about 50. But if I use it in Ope…

Hi, Please use jpegdec plugin and try the string: std::string gst_str = "v4l2src device=/dev/video0 io-mode=2 ! image/jpeg,width=1280,height=480,framerate=60/1 ! jpegdec ! videoconvert ! video/x-raw,format=BGR ! appsink"
