I'm successfully using the media9 package to compile presentation pdf's with embedded mp4 files. The problem is that after the video is done, and I am ready to change to the next slide, it takes at least 10 seconds until the pdf renders the next page. I usually work in Linux, but I'm trying to use Windows just to play this presentation. I'm using MiKTeX 2.9 to compile the slides, and the version of media9 compiled on March 27, 2013.

My slide is as follows:

    \includemedia[ label=vidA, 

I have tried using VPlayer.swf, and the videos did not play at all. I have also tried embedding the videos directly into the pdf i.e. not using a local webserver, and I get the same behavior. Any suggestions?

  • The deactivate=onclick option definitely seemed to help the situation significantly! Thanks for the advice. If you make it an answer, I'd be happy to accept it. Jun 21, 2013 at 17:35

The reason for VPlayer not working might be a wrong FlashVar for setting the video source. It must read source=... for VPlayer, while src=... for Strobe.

Try deactivate=onclick. This keeps the video + player app loaded when leaving the slide, and might reduce latency.

    But wouldn't that sort of hang Acrobat?, I mean if all the videos keep playing in the background at the same time?
