Hi,

Is it safe to use sdpops and the rtpproxy* modules together, given that
the latter modify SDP? In other words, can I prune some codecs first,
and then call rtpproxy_offer()? Is it safe?

Thanks,

Sorry, I didn't see the previous thread about this very issue. That was
a dumb post. The question arose entirely coincidentally.

To conclude here, it should work if you call msg apply changes, so the
sdp body is built again. I use this in a prototype deployment and seems
all going well. I did it only for requests, though.

Cheers,
Daniel

Hi Daniel,

You did not invoke rtpproxy symmetrically on replies? Or just not sdpops?

Hello,

just not sdpops. My specific need was removing video and then the
replies don't come with a video offering anymore. It is very likely to
be the same for codecs. Hoever, the msg_apply_changes() should work with
replies for latest version (or at least is on master).

Cheers,
Daniel
