Note that

1. `${VIDEO_PATH}` can be the local path or **URL** link to video file.

2. You can turn on the `[--use-multi-frames]` option to use multi frames for inference in the 2D pose detection stage.

3. If the `[--online]` option is set to **True**, future frame information can **not** be used when using multi frames for inference in the 2D pose detection stage.
