opencv录像在ARM Ubuntu 16.04运行报错

OpenCV(4.2.0-dev) ~/opencv/modules/videoio/src/cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can’t find starting number (in the name of file): outcpp.avi in function ‘icvExtractPattern’

解决方法:

注意文件名中需要有数字编号
错误的文件名:outcpp.avi
正确的文件名:outcpp001.avi

VideoWriter video("outcpp001.avi", focc, 8.6f, Size(frame_width, frame_height));
