# Change in Video embedding?

I am trying to embed a video in a beamer presentation. I must specify that the exemple below using media9 package was previously working. It is not working anymore, and I don't understand why. I am aware that many similar subjects were created, and from them, I managed to produce the working code linked below.

\documentclass[10pt]{beamer}
\usetheme{Frankfurt}

\usepackage{media9}

\begin{document}
\begin{frame}
\frametitle{title}

\includemedia[
width=1\linewidth,height=0.3\linewidth,
activate=pageopen,
passcontext,
flashvars={source=NRCollisionalQuenchToh.mp4
%&autoplay=true
%&loop=true
\end{frame}
\end{document}


Once again, this was working, but it's not the case anymore.

I am working on windows 10 using TexStudio as editor. The miktek console is up-to-date, and I have the latest version of adobe acrobat reader DC (20.013.20064).

It is compiled without error, and adobe open the pdf. Although, once on the slide, a small box appear to say its loading the video. Once the box show "ready" nothing happen, and the video don't play.

Also, I am aware that it should be possible to embed video in beamer directly with the multimedia package. I am totally fine with it, but I just never could get it to work. I am also aware tht it is possible to have external links, and I know how to do it, but this is not what I am looking for. Here is my code for that:

\documentclass[10pt]{beamer}
\usetheme{Frankfurt}

\usepackage{multimedia}

\begin{document}

\begin{frame}
\frametitle{title}
\movie[
poster,
showcontrols=true]
{Embedded}{water.avi}\\
\end{frame}

\end{document}


I am open to any solutions for embedded videos in a latex beamer, whatever video format I should use. I would prefer solutions using the media9 package, to be able to send the pdf to someone, whithout having to dend the video on the side, but at this point, I am fine with anything.

Thank you in advance for help.

• Can people watching this tell me if this bit of code is working for them at least? So I can have an idea about where the problem is coming from... Nov 4 '20 at 12:34

• Did you test whether both RichMedia methods (media9 and \embedvideo) work with the example video file example-movie.mp4 from pkg mwe? Maybe your video file has an encoding issue. Nov 20 '20 at 8:30
