I have been suffering from finding a PDF presentation viewer for beamer output on Windows that can play embedded videos (by media9 package) and show the elapsed presentation time.

I have tried the following:

Adobe Reader with tdclock package:

  • Pros: plays videos and loads tdclock properly
  • Cons: sluggish and crashes frequently

Foxit Reader with tdclock package:

  • Pros: smooth viewer and plays videos

  • Cons: can't load tdclock clock/stopwatch despite enabling javascript

Impressive:

  • Pros: fast and has internal clock

  • Cons: can't play embedded videos

Dual-Screen PDF Viewer:

  • Pros: very fast, has internal clock and dual screen support

  • Cons: can't play embedded videos

Is there any other solution that can properly play embedded videos and show elapsed presentation time flawlessly and smoothly on Windows?

P.S. when I mean tdclock javascript is not loaded, those empty red boxes show up instead of the clock/stopwatch,

enter image description here

and when embedded video can't be loaded, a white page shows up.

I think I figured out what made tdclock not load properly when using Foxit Reader.

I tried to follow the same way in this answer to add a clock in the footline instead of headline. However, it works only in Adobe Reader and failed in Foxit Reader (I don't understand why).

It seemed that the proper way to load tdclock clock/stopwatch is to place \initclock after \begin{document} as said in the package documentation not inside the preamble definition of headline/footline.

5 Macros

The clock must be initialized with \initclock, usually at the beginning of the document, after \begin{document}.

Before testing the following MWE in Foxit Reader, make sure you use the last version of free Foxit Reader 8.0.0.624 as of today. After installation, you may need to mark the document file/folder as trusted in Preferences > Security and make sure that javascript is enabled in Preferences > Trust Manager.

\documentclass{beamer}
\usepackage{lipsum}

\usepackage[font=Times,
timeinterval=30,
timeduration=20,
timewarningfirst=75,
timewarningsecond=90,
colorwarningfirst=blue,
colorwarningsecond=red]{tdclock}
\setbeamertemplate{footline}{%
    \hspace*{2ex}%
    \scriptsize{%
        \cronominutes~-~\tdhours\hspace{0.1ex}:\hspace*{0.5ex}\tdminutes%
    }%
    \hfill\insertframenumber/\inserttotalframenumber
    \hspace*{2ex}%
}

\author{Author}
\title{Title}

\begin{document}

    \frame[plain]{\maketitle\initclock}

    \begin{frame}
        \lipsum[1]
    \end{frame}

    \begin{frame}
        \lipsum[2]
    \end{frame}

\end{document}

It seems that Foxit Reader is the best choice for me to smoothly view a presentation with embedded videos and tdclock objects.

    Extract from tdclock documentation (p.4): "The clock must be initialized with \initclock, usually at the beginning of the document, after \begin{document}." – Paul Gaborit Jul 29 '16 at 17:25
  • Exactly that is what I read to fix my problem. Your comment reminded me to quote it inside the answer. Thanks. – Diaa Jul 29 '16 at 17:33
  • Ok. So, your sentence about package documentation is ambiguous... – Paul Gaborit Jul 29 '16 at 17:47
  • @DiaaAbidou : Your code doesn't work for me. Can you please provide the complete code, aka MWE ? – AlexG Jul 29 '16 at 19:19
  • @AlexG, check my MWE. Does it work? – Diaa Jul 29 '16 at 19:33
  • In AR yes, but not in Foxit-7.3.6.321 – AlexG Jul 29 '16 at 19:52
  • You can try last version of free Foxit Reader 8.0.0.624. After you install it, you may need to mark the document file/folder as trusted in Security in Preferences and make sure that javascript is enabled in Trust Manager. – Diaa Jul 29 '16 at 20:01
  • Ok. FR-8 works. Nice! – AlexG Jul 29 '16 at 20:30
  • Tried once more with a fresh Foxit-8 install, adding the file in the trust manager and enabling JavaScript doesn't help. Don't get the clock working. – AlexG Jan 10 '18 at 13:53
