Status: VERIFIED INCOMPLETE

(Core :: WebRTC: Audio/Video, defect)

Description

[boykinjim]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.57 Safari/537.36

Steps to reproduce:

Firefox version: 27.01 & Latest trunk 30

We have created a voip application which works fine in all the three webrtc enabled browsers - Chrome, Firefox and Opera with the exception that Firefox produces garbled audio is the stream is Opus mono. 

It's important to note that the:
1) Chrome/Opera plays it flawlessly 
2) Firefox plays fine if it's Opus stereo or any other codecs but not if it's Opus mono.

At the sending end, Opus is encoded using Opus profile OPUS_APPLICATION_VOIP

opus_encoder_create(48000, 1, OPUS_APPLICATION_VOIP, &err);




Actual results:

Garbled audio


Expected results:

Clean audio


Actual results:

Garbled audio


Expected results:

Clean Audio

Can you still reproduce it in latest Nightly in fresh clean new profile without any addons and plugins?
