Currently I’m writing on a professional article about Asterisk and Video-Calling.
One of the questions we want to answer is “What is the audio-quality like in a Video-Call?”
Can anybody tell me which Audio-Codec is used in combination with H.264 in Asterisk?
If I’m not completely wrong you can use H.264 with different Audio-Codecs.
Wow. You are absolutely incredible. I never got that fast a reply to a community-question in my life. Thank you.
I checked my Bria-Softphone on my iPhone. What I can select is the Video-Codec. And I can select the SIP-Audio-Codec like G.722. Is it that what you meant? Does the standard SIP-Audio-Codec of the SIP-Peer get combined with H.264 as Video-Codec?
They don’t get combined precisely. It negotiates separate media streams. One carries audio, one carries video. They aren’t muxed or combined together for transport.
No. I understand. The SIP-Protocol will say everything about the Audio-Stream and everything about the Video-Stream. But now I understand that I can configure audio exactly the same way like I do it for Non-Video-Calls.
