By the end of the previous comment I had experienced a weird bug. But I
decided to post it here as a separate comment because this is still
relevant to this thread.
I resolved the issues by:
1. changing the default player
2. opening a PDF document that contains a link to a local video
3. clicking the link to the video (and failing to open)
4. closing evince and opening the same document again
5. clicking the link to the video again (and succeeding this time)
I had to reproduce those steps for both totem and for vlc, ... but now,
everything just works!
After that initial hurdle, changing default players results in opening
the correct default video player.
I'm not really sure what happened, but the issue just fixed itself.
There are still some odd messages in the kernel log (see attached file).
I don't know if this is reproducible elsewhere, or if this bug should be
marked as resolved or not, as I'm way past due to do a clean install of
the newest Ubuntu:
rolandog@computer:~$ lsb_release -rd
Description: Ubuntu 20.10
Release: 20.10
rolandog@computer:~$ apt-cache policy evince
evince:
Installed: 3.38.0-1
Candidate: 3.38.0-1
Version table:
*** 3.38.0-1 500
500 http://nl.archive.ubuntu.com/ubuntu groovy/main amd64 Packages
100 /var/lib/dpkg/status
I hope this helps out someone getting unexpected behavior.

Title:
evince apparmor profile prevents movies from opening
Status in apparmor package in Ubuntu:
Fix Released
Status in evince package in Ubuntu:
Fix Released
Bug description:
Binary package hint: evince
Trying to open a movie with vlc or totem from within evince. I get the
error: "Failed to execute child process vlc (Permission denied)". The
same with totem.
I have been looking at all the "apparmor prevents" bugs that have been
reported of late. DVI printing, chromium, etc... the package
maintainers' strategy has been to add an exceptions to the apparmor
profile as the bugs come in. May I comment that this is a ludicrous
situation? There are going to be numerous helper applications that
people might want to use within a PDF file... why is apparmor blocking
them all?
