In short, this script automates the process of having to type the command below. The command uses the OpenPose software to pregenerate a video of a stick figure on a black background.
build\x64\Release\OpenPoseDemo.exe --video "C:\Projects\openpose-pregenerate-videos\videos" --hand --face --disable_blending --display 0 --number_people_max 1 --write_video "C:\Projects\openpose-pregenerate-videos\openpose_output\videos\output_video.avi" --write_json "C:\Projects\openpose-pregenerate-videos\openpose_output\json\output_keypoints.json"
Can you imagine typing this command for every video that you plan on pregenerating? Neither can I!
In the .gitignore, I am ignoring all files within \videos, \openpose_output\videos, and \openpose_output\json with an exception. The exception is that any .gitkeep file will not be ignored. This is done so that I can upload the empty folders to GitHub, which the script requires. Before running the script, be sure to delete the .gitkeep files from the 3 directories, otherwise the script won't work.
If you are using OpenPose on Windows, unfortunately the only video format that works with the --write_video flag is .avi.
I haven't tested with other video formats and I am unable to find documentation as to what video formats work with the --video flag. If you do happen to use another format aside from the one's listed and it works, please let me know!
