The replacement package is available on CTAN. It is called media9 and documented on CTAN.
Use the MiKTeX package manager for installation.
A simple example embedding an SWF would be:
\documentclass{article}
\usepackage{media9}
%\usepackage[dvipdfmx]{media9} % only for latex->dvipdfmx
\begin{document}
\includemedia[
activate=pageopen,
width=200pt,height=150pt,
}{}{myexample.swf}
\end{document}
A minimal example for embedding a video file, using the video player component VPlayer.swf shipping with media9 and using the pdflatex, lualatex, latex-->dvips-->ps2pdf or latex->dvipdfmx/xelatex (TeXLive-2012) work-flows would be
\documentclass{article}
\usepackage{media9}
%\usepackage[dvipdfmx]{media9} % only for latex->dvipdfmx
\begin{document}
\includemedia[
activate=pageopen,
width=200pt,height=150pt,
addresource=mymovie.mp4,
flashvars={%
source=mymovie.mp4% same path as in addresource!
% &autoPlay=true% % optional configuration
% &loop=true% % variables
}
]{}{VPlayer.swf}
\end{document}
Video files must be in the MP4 or FLV formats. Videos in other formats must be converted to MP4 or FLV, or recreated from the raw material. The H.264 codec gives high quality video at stunningly small file size. With ffmpeg, video files can be created easily.
From an existing video file, such as Sample.avi:
ffmpeg -i Sample.avi -vcodec libx264 Sample.mp4
From a numbered sequence of bitmaps, such as frame-0.png, frame-1.png, ... :
ffmpeg -i frame-%d.png -vcodec libx264 myvideo.mp4
