Fail to run demo (VideoCapture (IP camera/video) could not be opened for path)

[linjiangya]

Issue Summary

I finished compilation of openpose, however I got below when running demo.

Executed Command (if any)

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

and

./build/examples/openpose/openpose.bin --image_dir examples/media/ --display 0 --write_images output_images/ --logging_level 0 --disable_multi_thread

OpenPose Output (if any)

None

Errors (if any)

For --video examples/media/video.avi I got:

Did you ever solve this issue? I am having the same problem

For me this solution works!
The error could be due to OpenPose not having access to shared memory for graphical rendering. You can try enabling access to shared memory by running the following command:

export MIT_SHM_DISABLE=1
