I had been looking for that, but could not find it. Is it just vol->pts?

Aha, another thing I did not know about volumes.

But what is 'pass through' when this happens not at the beginning of a
stream, but later on? Does that mean 'no adjustment' or use the latest
available adjustment? The latest available would be preferable, but then
you have  to store the value somewhere. As far as I know this is not
done yet.
