Asterisk 16.11 StreamEcho()

bkervaski · June 16, 2020, 5:56pm

Hi all,

When using StreamEcho(6) I’m getting back just 1 stream and a bunch of inactive streams, here’s the streams from the channel, note the additional streams are of State “inactive” and Group “-1”.

Shouldn’t StreamEcho(6) be giving me 6 active streams? :: confused ::

Any insight appreciated!

You’d need to provide the full SDP negotiation, because ultimately it’s up to what the other side allows when a re-negotiation occurs.

Okay, this is helpful. I’m using JsSIP 3.5, going to dig in to the packets and report back. Thanks!

Just as a datapoint (still digging) but the same thing happens in the CMP2K demo when run against Asterisk 16.11 using Chrome or Firefox.

I wanted so bad to figure this one out on my own, but the issue escapes me.

Here’s the SDP’s, thanks for any insight, as always, very much appreciated.

If you open the apps/app_stream_echo.c source file and replace AST_STREAM_STATE_RECVONLY with AST_STREAM_STATE_SENDONLY, recompile and install, does it resolve the problem?

bkervaski · June 17, 2020, 8:00pm

Boom! Yep

You’re the man!

bkervaski · June 17, 2020, 8:08pm

This of course also fixes the CMP2K demo.

jcolp · June 17, 2020, 8:13pm

Please file an issue[1] with it, just mention that I’ll sort it out. I’ll upload the fix tomorrow morning on code review.
