I have a video.avi movie that I have converted to video.mp4 with ffmpeg using libx264 as follows:

ffmpeg -i video.avi -c:v libx264 -profile:v high -pix_fmt yuv420p -g 30 -r 30 video.mp4

Now I have tried to include it in a tex document "full screen mode" with media9. Minimal code:

\documentclass[
    paper=128mm:96mm,
    fontsize=9pt,
    pagesize,
    parskip=half-,
    numbers=noendperiod,
    captions=nooneline 
    ]{scrartcl}
\usepackage{graphicx}
\usepackage{media9}

\begin{document}
\thispagestyle{empty}
\begin{figure}[p]
\centering
\vspace*{-1.36cm} % to be in the right place
    \includemedia[
          height=\paperheight,
          activate=pageopen,        
          keepaspectratio,
          transparent,
          playbutton=plain,
          addresource=video.mp4,
          flashvars={
              source=video.mp4 
             &autoPlay=true
             &loop=true}
             ]{}{VPlayer.swf}
\end{figure}
\end{document}

This just produced a blank page, in newest Adobe Acrobat Reader for Windows with security settings disabled and multimedia enabled. Where do you think the problem lies? Thanks for the help.

Look at the terminal output of the LaTeX run. It tells you that the media annotation has zero width:

*************************************************
* media9 warning: "zero width"
* 
* Media annotation on line 28 has zero width.
* 
* Provide a poster text with non-zero width or
* set a valid one using the `width' option.
*************************************************

Therefore you get a blank page.

The warning message gives you instructions about what to do:

Either

  1. providing a poster text

or

  1. providing a non-zero width using the width option.

If you set the height only (height=\paperheight in your example), you need to also provide a poster text, such as \includegraphics{something} as the last-but-one argument of \includemedia:

\includemedia[
          height=\paperheight,
          activate=pageopen,        
          keepaspectratio,
          transparent,
          playbutton=plain,
          addresource=video.mp4,
          flashvars={
              source=video.mp4 
             &autoPlay=true
             &loop=true}
             ]{\includegraphics{example-image}}{VPlayer.swf}
