1560276 - Webrtc signal only VP8 as supported codec in SDP

Status: RESOLVED DUPLICATE of bug 814227

(Core :: WebRTC: Signaling, defect)

Description

[Francesco Durighetto]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/75.0.3770.80 Safari/537.36

Steps to reproduce:

I created a simple fiddle to reproduce:
https://jsfiddle.net/z7qpLhrk/

STEPS:

1. open the fiddle in two separate tabs of firefox.

TAB 1)

• click get media
• click create peerconnection
• click create offer
• copy the generated offer

TAB 2)

• paste the generated offer of the other tab in the "offer sdp" textarea
• tick the checkboxes "offer to receive video" and "offer to receive audio"
• click create peerconnection
• click set offer as remote
• click generate answer

Actual results:

the generated answer does not contains the H264 and VP9 codec, even if the offer does.

same goes for audio, no G722 PCMU or PCMA are signaled.

Expected results:

all capable codecs should be listed, then the sender will decide based on the priority which one to use.

I have tested this with osx and windows.
also tested with an older v62 build. same issue.

Am I missing something?
Thanks, Francesco
