If you encounter wrong scaling of PDFs within the presenter and presentation window, you can try the:
--wayland-workound
flag. See issue #312 and #214 for more informations.
You likely have a gstreamer codec issue. Try loading the video file you
want to play with the following command: gst-launch-1.0 filesrc
location=<your video> ! decodebin ! autovideosink If the video plays, go
ahead and submit an issue.
Otherwise, the command will likely output some good hints for why gstreamer
cannot decode the video.
For tiling window managers, the movement and fullscreening of the windows do not work reliable. It is therefore important to tell your WM to force floating the pdfpc windows.
If you are using i3-wm add this to your config file:
for_window [ title="^pdfpc - present" ] border none floating enable
