Cannot play wav file of opus into rtp_stream

[salmanchauhan]

When I am trying to play a .wav file of opus codec the audio is not clear and very distorted any help will be surely appreciated.

As far as I can tell, there is no built in support for Opus, only ulaw, alaw and g729. If these values match your opus codec, it might work, but if it doesn't, you'll surely get distorted audio.
