vlc always opens new window, rather than embedding about pympress

[gbaier]

Sorry for hijacking this issue. I had the same problem using fedora 28. Though the minmal working example did not work for me. The problem was that fedora uses Wayland instead of X11. The solution was simply to launch pympress the following way:

GDK_BACKEND=x11 pympress test.pdf

Hi @jpezaris, can you provide also your vlc version?

[jpezaris]

VLC media player 3.0.1 Vetinari (revision 3.0.1-0-gec0f700fcc)

Alright well there should be some error message somewhere. Maybe we don't manage to catch it because it's outside of python (e.g. VLC or Gtk).
Can you run pympress from a console in the following way, and tell me if there's anything error messages that are printed?

python3 -m pympress <file.pdf>

[jpezaris]

This is the only message: (__main__.py:11842): Gtk-WARNING **: Allocating size to GtkPaned 0x562958d74f20 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?

Even when playing the VLC embed? Can you copy the sources of the beamer file?

[jpezaris]

I had not looked, and you are right: it happens at startup, and not when the movie is clicked. Perhaps this is an important clue: I have found that by changing the File Associations for MP4 files in System Settings, I can switch whether VLC or another program (e.g., mplayer) gets called when the movie pane is clicked within pympress.

So no messages at all when the movie is clicked? Also what beamer package do you use to include the video? Could you share the sources of a minimal compilable latex file here?

Sounds like you use the external option of the media package in your .tex file

[jpezaris]

\documentclass{beamer} \begin{document} \begin{frame} \href{run:test.mp4}{\includegraphics[height=0.2\textwidth]{test.jpg}} \end{frame} \end{document} ... the files test.jpg, test.mp4, and test.pdf are available from http://pezlab.org/test.jpg http://pezlab.org/test.mp4 http://pezlab.org/test.pdf The beamer version is Document Class: beamer 2015/01/05 3.36 A class for typesetting presentations (rcs-revision 8a39122e1f63)

Alright that seems to be a link to open the file in its default program, which we do correctly.

Try this:

\documentclass[10pt]{beamer}
\usetheme{Warsaw}
\usepackage{multimedia}

\begin{document}
   \begin{frame}[plain]
      \movie[height=.2\textwidth]{\includegraphics[height=.2\textwidth]{test.jpg}}{test.mp4}%
   \end{frame}
\end{document}

[jpezaris]

Awesome, thanks! Now the video in the minimal example works correctly. The call to \usetheme{Warsaw} is not necessary, I've found. However, when you expand the minimal example as follows: \documentclass[aspectratio=169,20pt]{beamer} \usepackage{multimedia} \usepackage{pgfpages} \setbeameroption{show notes} \setbeameroption{show notes on second screen=right} \begin{document} \begin{frame} \movie{\includegraphics[width=0.8\textwidth]{test.jpg}}{test.mp4} \end{frame} \end{document} The resulting movie plays, but has the wrong size and position, compared to the frame grab, which remains correct. The problem remains the same whether the width is specified in absolute size (e.g., "width=4in") or as a fraction of \textwidth.

Alright, that's a different issue. Only with notes on second screen it appears.

@gbaier Thank you so much! That was exactly my problem running pympress under xwayland fixed it for me as well!
Is there any chance to make the internal video player also work on wayland? :)
Great project tho
