Re: [OpenSIPS-Users] RTPEngine - changing codec format parameters from default values when transcoding - OpenSIPS 3.1

[Mark Allen]

Just posting this to document the end result. The following line to
pass the transcoding parameters I wanted directly to the RTPEngine daemon
worked for me:


transcode-opus/48000/2/32000//stereo--0;useinbandfec--1;maxplaybackrate--16000;sprop-maxcapturerate--16000

NB - The '--' part means '=' and is there to avoid parsing errors in
RTPEngine

Ah! Thanks Răzvan and Johan. I was thinking that the options described in
the OpenSIPS RTPEngine module documentation were the only ones
available, but I missed the key phrase...

*When passing an option that OpenSIPS is not aware of, it will be
blindly sent to the rtpengine daemon to be processed.*

...I should be fine from here I think. Thanks for your help.

Re: [OpenSIPS-Users] RTPEngine - changing codec format parameters from default values when transcoding - OpenSIPS 3.1

[Răzvan Crainea]

I think the proper way to do it is 
`transcode-opus/48000/2/32000//maxplaybackrate--48000;stereo--0;useinbandfec--1;maxaveragebitrate--32000`
Anyway, as Johan suggests, follow the rtpengine documentation, you will 
find more info there.

No. I'm not sure how I would specify this in the opensips.cfg 
rtpengine_offer parameters. From the documentation for the 
rptengine OpenSIPS module, it doesn't seem as if something like the 
following is an option...


 
transcode-opus='opus/48000/2/32000//maxplaybackrate=48000;stereo=0;useinbandfec=1;maxaveragebitrate=32000' 



...however, if I have tried this in the code (with or without quotes) it 
doesn't produce an error, either from OpenSIPS or rtpengine, but neither 
does it do anything - Opus fmtp in the SDP is not changed. I guess I'm 
looking for the correct OpenSIPS syntax to pass these parameters 
successfully to rtpengine

Follow the rtpengine documentation. The necessary flags are given there,
just pass them in an avp to rtpengine_offer or answer

Hi, Mark!

OpenSIPS passes the commands to RTPengine as you supply them, so in 
theory this should be supported. Did you try to set this up? Can you 
provide any logs about this?

I'm using RTPEngine for transcoding between Opus and PCMU. According to
