To pop up your default video player upon click in Beamer LaTeX-generated PDF, use the LaTeX syntax

\href{run:myvideo.avi}{my cool video}

You must use either

• relative path (e.g. ../data/myvid.avi gfx/myvid.avi)
• fully resolved absolute path (e.g. /home/joe/data/myvid.avi)

These will NOT work

• ~
• $HOME
