Please be more explicit on what your are trying to achieve, why you
think your solution is correct, what does not work in your solution
and what you did to try to make it work.  This will boost the odds
of getting an answer.

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:

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?

Hi,

Maybe by replacing "%s -ss %s %s" by "%s -ss %s \"%s\"", i.e. adding
double-quotes around the filename?

BTW, the video link works fine on a few files I tried on my disk.
