SDP attribute manipulation or codec managment per stream?

[Eric Dev]

Hello i would like to know if rtpengine has currently the feature to do per stream operation.

suppose receiving this as ingress

v=0

o=PBX 1000 1000 IN IP4 x.x.x.x

s=-

c=IN IP4 x.x.x.x

t=0 0

m=audio [port1] RTP/AVP 8 18 101

a=rtpmap:8 PCMA/8000

a=rtpmap:18 G729/8000

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-15

a=ptime:20

m=audio [port2] RTP/AVP 18 9 101

a=rtpmap:18 G729/8000

a=rtpmap:9 G722/8000

a=rtpmap:101 telephone-event/8000

a=fmtp:101 0-15

a=ptime:20

can i strip G729 only for stream audio on port1 ?

can i apply sdp-attr manipulation only for stream audio on port2 ?

No, we don't have such an option. Attribute manipulations can be applied based on media type only, and codec manipulations are global.

Cheers
