fmtp - attributes are considered payload format parameters, therefore
they're not filtered by this filter.

If you want to have a go at the code, have a look at filterSDPalines
in SDPFilter.cpp, and filter also sdp_format_parameters of
media.payloads. I'd say it would make sense to have
'sdp_alinesfilter_list=vad' then.
