Today we are proudly releasing libav 11.9.

This is the 8th bugfix release for the major release 11.

Here are the updated changelogs: Changelog for 11.9

We encourage distributors and system integrators to update, and share their patches against our release branches.

If you need or want monthly releases for the current release branch, builds for specific platforms or you just want to help and you do not know how, we welcome donations through Bountysource.


After almost 2 years of hard work, the Libav community is happy to announce that version 12.0 has been released!

What changed? See the changelog here.

As this is an even-numbered release, please be aware that while care has been taken to keep it as minimal as possible, this release may break ABI and API for our users and so will most likely require applications to be recompiled.

We would like to take this opportunity to say thank you for all the efforts of our developers, contributors, testers, and the infrastructure team, without which this release would not be possible.
