Error: VideoCapture (IP camera/video) could not be opened for path: 'examples/media/video.avi'. If it is a video path, is the path correct?

[youxiandeduguo]

I am running Openpose on the server, so I set it up without a GUI, but an error occurred when I ran the following command

./build/examples/openpose/openpose.bin --video examples/media/video.avi --write_images output_images/ --display 0

It was just an error in the title, and I tried to search for it later

It should be because there is a problem with the link to the FFMPEG library, but now I don't know how to fix it

If you have time, could you help me take a look, sir
