Liquidsoap 2.2.5

This is the fifth release of the 2.2.x release cycle, following the initial 2.2.0 release.

This release comes with some minor bugfixes and changed feature and one big chunk of new functionality around crossfading: autocue.

We will post a longer article about this on our blog. The gist of the functionality is that it should allow to compute excellent crossfade transition parameters in your sources, at the expense of an increased CPU usage.

Users can register their own autocue implementations and there is a default one that is available if you have compiled liquidsoap with its ffmpeg support.

In this case, you can try to add:

enable_autocue_metadata()

To your script and see what happens!
