Since jack inputs do not have metadata or track marks, you will need to
insert those yourself at the required time.
In this page: http://www.liquidsoap.info/doc-1.3.3/metadata.html you will
find a detailed example that should guide you through the process.
Basically, you need to do the following:
* Use insert_metadata to obtain a way to programmatically insert new
metadata. This is described in the example
* Use add_timeout to run a function every 10 seconds
* Write the function to insert metadata that will be executed each 10
seconds. This part you almost already have it.
Additionally you may want to use a variable reference to keep track of the
last inserted metadata and only update if it has changed.
Hope this helps!
