I try to add a new link like this:

[[video:/path/to/file/video.mp4::00:13:05]]

The following "00:13:05" is a timestamp, mplayer support play video
start from a specific timestamp. So I use following code snippte:

> I have following code, check out the FIXME: comment tag.
> How to get the correct link here?

> | ;;; `video:filename.mp4::start_timestamp'

> | (defun org-video-link-open (uri)
> |   "Open video file `URI' with video player."

But it does not open video file. After edebug, seems error on file path.
The problem is how to convert org file: link path into shell path. When
org file link path contains space " " or colon ":", comma "," etc
special characters. How to escape them safely into shell file path?
