I usually name these filters "utility filters".

Note that there are also "information filters" that modify neither the
frame data nor the metadata and just extract and prints information. (We
still need a framework to let users reliably extract that information,
just printing in the log is not sustainable, and neither is each filter
inventing it own solution. But that would require an unified efficient
string API.)
