So much about the "easy" part. I tried to match two groups now (and get
the first into a different record stored in $2) like this:

in
"%.1/uid=\$1.*?connected-uid=(\$2)([-a-zA-Z0-9]+)/
%.1/.*?device-identifier=([-a-zA-Z0-9]+)/";

This basically passes manual testing on regex101 (matches two groups as
desired), but fails with streamdevice with "input does not match format". I
guess I am doing soemthing wrong when trying to parse two regex into
different channels. Is there an example somewhere how to do this properly?
