pdf with movie demonstrating the problem
Hi,
This is an old bug. I have an issue with vlc-phonon backend which might be the
same issue, but I am not sure.
I am trying to build pdf with embedded movie; I am using latex with the
beamer/multimedia package. The idea is that a rectangle on the pdf is defined,
and when the user clicks on it (using a compatible pdf reader; I am using
okular), the video is played tight on top the rectangle, as if it was embedded
in the pdf itself. Internally, okular uses the poppler library which calls
phonon which uses vlc.
I am using a video with a 2:1 aspect ratio, and I define a rectangle with the
same aspect ratio. My problem is that the video occupies the full height of the
rectangle, but not its full width: it has been squeezed horizontally, and black
bands appear on both sides. In order for the video to fill the whole rectangle,
it seems that the rectangle must have an aspect ratio of 7:4.
Now here's the catch: the problem seems to appear only using Wayland. It seems
to be working as expected with X11. I am using an uptodate fedora38 beta.
I have attached a pdf file embedding twice the same movie: once onto a
rectangle with a 2:1 aspect ratio, and once onto a rectangle with a 7:4 aspect
ratio. The video should fit the first rectangle, and horizontal black band
should appear in the second rectangle. this works as expected under X1. Under
wayland, the video is squeezd and fits the second rectangle. On the first
rectangle, vertical black bands appear. For documentation, I have also included
the latex file.
Is this the same bug? Should I open a new one? Is there a workaround?
