Hi,
we've got a recurring issue which is described here:
https://github.com/AzuraCast/AzuraCast/issues/1415
The expected behavior is this:
1. at 4pm a show A is scheduled to play.
2. at 5pm show A ends and a jingle is played.
3. right after step 2 a new show B is scheduled to play (approx. 1 minute after
5pm).
The actual behavior was this:
1. same.
2. same.
3. new show B won't start (see error in log), instead a fallback will be used.
I speculate that the error may have to do with the fact that show A is more
than 1 hour long. As a result, Liquidsoap cannot start show B on time also
because playing the jingle takes time too. Shouldn't Liquidsoap be resilient
against a situation like this? As you can see in the configuration below we're
using predicates such as `{1w and 17h-18h}` and I would expect the predicate to
be true at 17:02 as well.
Do you have any idea how to fix it?
Here is the context of the error from the Liquidsoap log:
