Original GitHub issue: https://github.com/netblue30/firejail/issues/4978

Description

Playing any video fails with ffplay under firejail's current profile.

Steps to Reproduce

Install ffmpeg and firejail and play a video file after running firecfg.

Expected behavior

It should play the video.

Actual behavior

Errors out with error code 139

Behavior without a profile

Plays video just fine.

Additional context

Adding:

ignore dbus-user
ignore dbus-system

to ffplay.local resolves the problem.

Environment

Linux distribution: Arch Linux
Firejail version: 0.9.68

Checklist

The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
[x I can reproduce the issue without custom modifications (e.g. globals.local).
The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
The profile (and redirect profile if exists) hasn't already been fixed upstream.
I have performed a short search for similar issues (to avoid opening a duplicate).
- I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

I can not reproduce this (Fedora Linux 35).

Same here, ffplay works fine on my Arch Linux box.

$ pacman -Q ffmpeg
ffmpeg 2:5.0-4

I remember seeing something on issues with ffmpeg 5.x and Firefox on the Arch Linux forums. Do you happen to have ffmpeg4.4 installed?

I do in fact have both ffmpeg4.4 and ffmpeg 2:5.0-4 installed. I would appreciate a link to the Arch Linux forums if you still have it @glitsj16 .

Having ffmpeg4.4 installed alongside ffmpeg is the correct 'fix' for firefox video play on Arch Linux. Here are the links I found:

Looking through the forums, I did actually have the issue mentioned in the forums, but restarting firefox actually fixed it for me.

However, since no one can reproduce this issue, it seems to be a configuration-specific problem, so I'll close this issue.

Thanks for the help.
