在ARM板上安裝ubuntu16，編譯安裝了OPENCV4.1.1+CONTRIB ,編譯前已經確定了
Video I/O:
DC1394: NO
FFMPEG: YES
avcodec: YES (58.35.100)
avformat: YES (58.20.100)
avutil: YES (56.22.100)
swscale: YES (5.3.100)
avresample: NO
GStreamer: NO
v4l/v4l2: YES (linux/videodev2.h)
但是我執行報錯：
cv::VideoCapture cap;
cap.open("rtsp://admin:[email protected]:554/MPEG-4/ch1/main/av_steam");
[ERROR:1] global /media/debian/ubuntu-ext/opencv_ubuntu/opencv411/modules/videoio/src/cap.cpp (116) open VIDEOIO(CV_IMAGES): raised OpenCV exception:
OpenCV(4.1.1) /media/debian/ubuntu-ext/opencv_ubuntu/opencv411/modules/videoio/src/cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can't find starting number (in the name of file): rtsp://admin:[email protected]:554/MPEG-4/ch1/sub/av_steam in function 'icvExtractPattern'
