Acrobat uses two SWF files that play FLV and MP3, these are \texttt{VideoPlayer.swf} and \texttt{AudioPlayer.swf}. You can communicate with these two SWF using the \texttt{callAS} method of the \texttt{AnnotRichMedia} object, as documented in the \textsl{JavaScript for Acrobat API Reference} guide. The \texttt{callAS} method passes function names have been exposed (to external use) using the \texttt{ExternalInterface.addCallback} in ActionScript. These exposed methods are \texttt{multimedia\_play}, \texttt{multimedia\_pause}, \texttt{multimedia\_rewind}, \texttt{multimedia\_seek}, \texttt{multimedia\_nextCuePoint}, \texttt{multimedia\_prevCuePoint}, \texttt{multimedia\_volume}, and \texttt{multimedia\_mute}. In this demo file, we illustrate the use of \texttt{multimedia\_play}, \texttt{multimedia\_pause}, and \texttt{multimedia\_rewind}. Basically, the technique is first to get the AnnotRichMedia object of the target annotation using either \texttt{Doc.getAnnotsRichMedia()} or \texttt{Doc.getAnnotRichMedia()} methods. \begin{verbatim} var rm = this.getAnnotsRichMedia(this.pageNum)[0]; \end{verbatim} Here we get the first rich media annotation on the current page. If we want to play the media, we might do something like this \begin{verbatim} if ( rm ) { if (!rm.activated) rm.activated=true; rm.callAS("multimedia_play"); } \end{verbatim} If we want to play the media, we might do something like this \begin{center} \resizebox{2in}{!} {\rmAnnot[poster=aebmovie_poster]{640bp}{480bp}{horse1}}\\[1ex] \scriptsize \pushButton[\CA{Play}\textSize{5}\A{\JS{% var rm = this.getAnnotsRichMedia(this.pageNum)[0];\r if ( rm ) {\r\t if (!rm.activated) rm.activated=true;\r\t rm.callAS("multimedia_play");\r } }}]{horse1Play}{}{9bp}% \pushButton[\CA{Pause}\textSize{5}\A{\JS{% var rm = this.getAnnotsRichMedia(this.pageNum)[0];\r if ( rm ) {\r\t if (!rm.activated) rm.activated=true;\r\t rm.callAS("multimedia_pause");\r } }}]{horse1Pause}{}{9bp}% \pushButton[\CA{Rewind}\textSize{5}\A{\JS{% var rm = this.getAnnotsRichMedia(this.pageNum)[0];\r if ( rm ) {\r\t if (!rm.activated) rm.activated=true;\r\t rm.callAS("multimedia_rewind");\r } }}]{horse1Rewind}{}{9bp} \end{center} The above video has play, pause, and rewind buttons that use the scripting bridge to communicate with the underlying \texttt{VideoPlayer.swf}.\footnote{Video downloaded from youtube.com.} These techniques are for FLV and MP3 files only. A SWF file would not obey \texttt{multimedia\_play} method, for example. \end{document}
