Graphics, Figures & Tables ⇒ Run video automatically in beamer

[math004]

I have used the following code:
\documentclass[12pt,landscape]{article}
\usepackage{geometry}
\geometry{verbose,letterpaper}
\usepackage{movie15}
\usepackage{hyperref}
\begin{document}
Whispering-gallery mode in a quarter circle:
\begin{figure}[ht]
\includemovie[
poster,
text={\small(Loading Circle-m-increase3.mp4)}
]{6cm}{6cm}{Circle-m-increase3.mp4}
\end{figure}
\end{document}

The problem in runing the video via pdf, the message shewn is:
""" Lecteur correspondant introuvable pour cette vue """"
