System level FFmpeg support for Firefox

x3x7 — Sat, 27 Jun 2026 12:31:15 GMT

I am not a Firefox developer but looking at the code there is FFmpeg included at dom/media/platforms/ffmpeg. Unfortunately there is no support for using the system level FFmpeg if available. This would allow for up to date audio/video codec support.

Would it be possible the use the system level FFmpeg in a future Firefox version?

Are you living under a rock? After all the recent FFmpeg security issues, why would Firefox want to depend on whatever system FFmpeg version happens to be installed? Bundling a known, tested version gives Mozilla much more control over security updates and compatibility.

As you wrote, security fixes can more easily be updated to the system FFmpeg than to the bundled version. Please also note that I did not ask to replace the version included but to allow the option of a system level support if so desired.
