They are safe for filtering for the FOP2 manager user. Do not set them for the admin user or any user that might be used by other applications. Also, check the fop2 documentation for the latest version of recommendations/setup at www.fop2.com/docs. I have seen in some systems that rtcp events should be filtered out via wildcard, like RTCP* , for example.

I wrote an entry in the blog showing the events you can filter out:

The list is not complete, but this events are safe to filter right now.
