% - Marco Aurélio Graciotto Silva
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% This package allows direct embedding of flash movies into PDF files. It is
% designed for use with pdflatex.
%
% Basically it uses the fact that the Adobe Reader 9 contains an embedded Adobe Flash
% player which can be invoked with the "rich media annotation" feature which is described
% in "Adobe Supplement to the ISO 32000 BaseVersion: 1.7 ExtensionLevel: 3".
%
% advantages:
% - You can directly embed videos into the pdf (external window is optimal and not necessary).
% - You can play back videos without worrying about platform dependencies.
%
% disadvantages:
% - You can only play back embedded videos with Adobe Reader 9 and upwards.
%
% example (1)
% - download a video file to use, for example
% http://heasarc.gsfc.nasa.gov/Videos/historical/saturn5.avi
% - transform this video into the flash format with ffmpeg:
% ffmpeg -i saturn5.avi saturn5.swf
% (or use any other program capable of this, for example mencoder)
% - put following line into your tex-file:
% \flashmovie[width=10cm,height=10cm]{saturn5.swf}
% (both width and height are needed!)
% - translate with pdflatex
% - advantages:
% - easy
% - does not rely on external components
% - disadvantages:
% - ffmpeg is incapable of embedding h.264 into swf-files, so one can only
% use inferior video codecs (sorenson h.263 aka flv,...).
% - no controls (play,pause,stop,seek,...) possible
%
% example (2)
% - warning: The following example assumes that you have obtained VideoPlayer.swf
% and SkinOverPlaySeekStop.swf from Acrobat 9 Pro and put it into the working
% directory.
% - download a video file to use, for example
% http://heasarc.gsfc.nasa.gov/Videos/historical/saturn5.avi
% - transform this video into the mp4 format with ffmpeg:
% ffmpeg -i saturn5.avi -vcodec libx264 -vpre hq -crf 22 -acodec libfaac -ab 128k -ac 2 saturn5.mp4
% (or use any other program capable of this, for example mencoder)
% - alternatively the flv-format with video-codec sorenson h.263 (aka flv) and audio-codec mp3 is also possible:
% mencoder saturn5.avi -o saturn5.flv -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=300:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -ofps 24 -vf harddup -oac mp3lame -lameopts abr:br=56 )
% (or use ffmpeg to do the same thing...)
% - put following line into your tex-file:
% \flashmoviex[width=10cm,height=10cm]{saturn5.mp4}
% (both width and height are needed! instead of saturn5.mp4 one can also use saturn5.flv but not saturn5.swf)
% - translate with pdflatex
% - advantages:
% - controls (play,pause,stop,seek,...) possible
% - superior video codec possible (h.264)
% - one can directly embed mp4 and flv files without conversion
% - disadvantages:
% - use of external non-free components.
%
% todo:
% - replace VideoPlayer.swf and SkinOverPlaySeekStop.swf by some freely available software.
% it should be possible to program a simple video player with flexsdk and activescript.
% the video-player should play mp4 and flv files and should and be capable of play,pause,seek,stop.
% controls should be hide-able.
% - make more options of rich-media annotations usable, for example activation by clicking, play-count,...
% - display a picture when the player is deactivated.
% - efficient multiple inclusion of video files.
%
% warning:
% - Because the file names of the movies are directly embedded into the PDFs please use only
% "normal" file names. More specific use only names compatible with internal PDF strings.
% There is even a specification what conforming file names are (see the PDF reference).
