I am using different approach..it may not be the best approach to add the movies in latex as resulting PDFs size go much higher.
save the movie as images the .jpeg file by getframe or print command frame by frame instead of generating the movie .avi.
and use \usepackage{animate} in latex to add the movie. here is the code that i use.
\begin{figure}[H]
\centering
\animategraphics[loop,label=label1,poster=last,width=\linewidth]{3}{name of image}{start no}{end no}
\mediabutton[
jsaction={if(anim.label1.isPlaying)
anim.label1.pause();
else
anim.label1.playFwd();
}
]{\fbox{Play/Pause}}
\caption{caption as needed}
\end{figure}
