###Acrobat Reader

linenums | Acrobat Reader

\usepackage[controls]{animate}
 
\begin{figure}
    \animategraphics[width=6cm]{3}{basename_}{28}{63}
\end{figure}

###Okular et pdfpc

linenums | Okular and pdfpc

\usepackage{multimedia}
 
\movie[
  height = 6cm,
  width = 6cm,
  showcontrols,
  poster
] 
{}{GB_irrad_these_2.avi} % codec: theora, pas de mpeg

For Okular, you may want to change the backend of Phonon (which is used by Okular to play videos) to the VLC one.

sudo apt install phonon-backend-vlc

On newer versions of Ubuntu, the crucial package is phonon4qt5-backend-vlc

{
    \href{run:#2?#1}{\includegraphics[#4]{#3}}
}
\begin{frame}[t]{title}
    %\inlineMovie[loop&autostart&start=5&stop=12]{file.avi}{thumbnail.jpg}{height=0.7\textheight}
