Video embedded into the PDF of a LaTeX beamer document as flash makes Acrobat Reader 9.4.1 crash on slide transition

Question

I have tried to embed a .flv video file into a PDF using either the package flashmovie or the package media9 together with beamer and pdfLaTeX, as described, for instance, here.

The video is shown correctly in Acrobat Reader 9.4.1 on Ubuntu. However, the reader crashes when I move on to the next slide, irrespective of the contents of that slide. The reader issues the error message (acroread:7653): Gdk-WARNING **: gdk_window_set_user_time called on non-toplevel.

Has anyone come across this problem and knows the reason/a solution?

Is the procedure described above still the recommended way of including videos into PDFs? Given that Acrobat Reader does not support flash anymore, it seems like there should be better ways.

Here is a minimal non-working example with the flashmovie package:

\RequirePackage{flashmovie} 
\documentclass{beamer}
\usepackage{flashmovie}
\begin{document}
    \begin{frame}
        \flashmovie[engine=flv-player,loop=1,width=146px,height=108px,auto=1,controlbar=0]{movie.flv} 
    \end{frame}
    \begin{frame}
    \end{frame}
\end{document}

Here is a minimal non-working example with the media9 package:

\documentclass{beamer}
\usepackage{media9}[2013/11/12]
\begin{document}
    \begin{frame}
        \includemedia[width=146px,height=108px,activate=pageopen,addresource=movie.flv,flashvars={source=movie.flv}]{alternative}{VPlayer9.swf}
    \end{frame}
    \begin{frame}
    \end{frame}
\end{document}

Answer 1

Alexander Grahn's animate package is a great fallback option that works beautifully when converting videos to sequences of images.

Answer 2

Quote from the file flashmovie.sty:

There seems to be some trouble with the latex package beamer. You can't use
the flv-player reliably with it. It is prone to crash the acrobat reader while
changing pages.

Instead, you could try the media9 package (myvideo.flv to be replaced by some file of yours):

\documentclass{beamer}
\usepackage{media9}[2013/11/12]

\begin{document}
\begin{frame}{Video}
  \includemedia[
    width=0.4\linewidth,height=0.3\linewidth,
    activate=pageopen,
    addresource=myvideo.flv,        %adjust
    flashvars={source=myvideo.flv}  %adjust
  ]{\frame{Click!}}{VPlayer9.swf}
\end{frame}

\begin{frame}{Other}
  \dots stuff
\end{frame}
\end{document}
