 \section{Introduction}
-This package provides an interface to embed interactive Flash (SWF) and 3D objects (Adobe U3D \& PRC) as well as video and sound files or streams in the popular MP4, FLV and MP3 formats into PDF documents. Playback of multimedia files uses the built-in Flash Player of Adobe Reader and does, therefore, not depend on external plug-ins. Flash Player supports the efficient H.264 codec for video compression.

Flash Player supports the efficient H.264 codec for video compression.
 
-Among the supported media types, video and sound files require an additional Flash (SWF) application for playback, which must be either embedded into the PDF or loaded at runtime from the internet. There are numerous such players, both open-source and commercial, available on the internet. One of them is the highly configurable open-source `Strobe Media Playback'~\cite{strobe}, maintained by Adobe and downloadable from SourceForge.net. Package `media9' comes with two simple players for video and audio, `VPlayer.swf' and `APlayer.swf', which can be used instead. They provide sufficient functionality for playing embedded files and streamed media.

-\emph{Note:} `media9' package replaces the now obsolete `movie15' package. `media9' is based on the RichMedia Annotation, an Adobe addition to the PDF specification~\cite{supplement}, while `movie15' uses the old multimedia framework (`Screen Annotation') of pre-9 Readers which depends on external plug-ins and which does not support recent media file formats.

 A YouTube video clip, as shown in Fig.~\ref{alien}, may serve as a basic example of loading Flash content from a URL to be displayed in an embedded fashion in a PDF document. Indeed, a YouTube clip is nothing more than a small SWF file which loads a video stream and other necessary resources, such as user controls and a player skin from a remote server. It can be configured via ActionScript variables, to play several videos in a row, to play a video in a loop etc. Player parameters are documented on \url{http://code.google.com/apis/youtube/player_parameters.html} and can be passed to the player using either the `\verb+flashvars+' option, as in the example, or appended to the URL string after the video ID. A question mark `\verb+?+' must be put between the video ID and the parameter string. Some of the documented parameters, such as `\verb+rel+', seem to have an effect only if they are passed as part of the URL.

-Video and sound files are always loaded and then played by a media player application. Two simple players, `VPlayer.swf' for video and `APlayer.swf' for sound, are installed along with the `media9.sty' package file. Although they do not have user controls, minimal interactivity for play, pause and resume is provided via left mouse button press and release. The players support MP4 video and MP3 sound files and streams. They were compiled, using the free Adobe Flex SDK~\cite{flex}, from XML source files which reside in the same directory as the players. More sophisticated players are available, e.\,g.~\cite{strobe}. There is no need to copy `VPlayer.swf' and `APlayer.swf' into the directory of the document source for embedding. They will be found by \LaTeX{} without taking any further action.
+Video and sound files are always loaded and then played by a media player application. Three players are installed along with the `media9.sty' package file: two simple players, `VPlayer.swf' for video and `APlayer.swf' for sound, and a fully blown one, `StrobeMediaPlayback.swf', with some fixes to improve its usability. The simple ones are `chromeless' players, that is, they do not have user controls. Minimal interactivity for play, pause and resume is still provided via left mouse button press and release. They were compiled, using the free Adobe Flex SDK~\cite{flex}, from XML files which reside in the \verb+doc/+ folder of the package installation. For `StrobeMediaPlayback.swf', only a patch file is included, as the sources can be downloaded elsewhere.
+
+The included version of `StrobeMediaPlayback.swf' is preferably to be used, as it is smaller than `VPlayer.swf' in terms of file size and it provides user controls. The improvements of `StrobeMediaPlayback.swf' in comparision to the original version on SourceForge.net are
+\begin{itemize}
+  \item fix: video could not be restarted after end of playback if ActionScript variable `{\tt autoRewind}' is set to `{\tt false}'
+  \item new: first frame of video is shown as default poster instead of black stage
+  \item new: play/pause video by clicking on the stage (as with `VPlayer.swf'), useful in a lecture situation
+\end{itemize}

 Below, two examples of embedded 3D files are shown. The first one, Fig.~\ref{asyex} is a PRC file generated with Asymptote. Note the text labels always facing the camera thanks to the attached 3D JavaScript file `asylabels.js'. The second example, Fig.~\ref{u3dex}, demonstrates the use of a views file which defines additional named views of the 3D object. Moreover, the possibilities of the extended 3D context menu can be evaluated. They were enabled by adding the `\verb+3Dmenu+' option to \verb+\includemedia+. All part and scene rendering attributes that can be changed via the `\emph{\sffamily Part Options}' and `\emph{\sffamily Viewing Options}' menu entries, as well as a cross section to be added with the `\emph{\sffamily Cross Section}' menu entry can be saved into a new view (`\emph{\sffamily Get Current View}'). Position, orientation and scaling of individual parts and of the cross section can be changed using the keyboard (keys \keys{\arrowkeyleft}, \keys{\arrowkeyright}, \keys{\arrowkeyup}, \keys{\arrowkeydown}, \keys{X}, \keys{\shift+X}, \keys{Y}, \keys{\shift+Y}, \keys{Z}, \keys{\shift+Z}, \keys{S}, \keys{\shift+S}).
