Hello,
I’m developong system which will be using Wowza Engine. I’m receiving audio and video from devices. They are sending video as h264 AVC codec and audio as PCMU. I’m receiving them separately. For now I only have managed to display video without sound. Is that mean that I should pack video and audio in some container and then send signal to Wowza o du something another way to achieve sound in video?
Best regards,
Bart

Hello,
Thanks for contacting the Wowza Community!
Wowza does not support that audio codec. Here is a link of supported codecs Wowza accepts for input:

Hope this helps. If any further questions, feel free to contact us.

Hello, thanks for replying. Shouldn’t transcoder deal with my PCMU input? It is G.711U exactly.
