Steps to reproduce:

I use firefox(version 61) to test
I set these lines under audio m line in SDP offer& SDP answer:
m=audio 1 RTP/SAVPF 111
a=rtpmap:111 opus/48000/2
a=maxptime:60
a=ptime:60"
means I want to sent 60ms packet size of OPUS


Actual results:

But firefox still send 20ms packet size


Expected results:

I want to sent 60ms packet size of OPUS.
Seems that the a=ptime didn't make sense.
So How can I control the opus packet size as I want?

As far as I can tell, we parse the ptime and maxptime attributes in sdp, but then don't actually use the values anywhere.

Thanks for your reply.
So do you have a way to control the opus send packet time as I want(i.e. 60ms)? acturlly it sent 20ms packet time now
And do you have plan to support "ptime" attribute not only parse it?

:drno, what do you think about supporting ptime, assuming I'm correct, and we're only parsing it, not using it?
