AMR-WB support

[mehmetozi]

Hi,

Is there any plan to support AMR-WB codec?
Or do I need any codec support while using SFU? Because I just want to forward audio and video RTP/AVP packets as one-to-many,

Regards

The codec must be present in the supportedRtpCapabilities list in order to be usable in mediasoup.

mediasoup :: API

Please, don’t make us investigate what you mean. Could you explain why AMR-WB codec is important? for what? is audio? video? simulcast? SVC? WebRTC? which devices?

Amr-wb is a mandatory audio codec within some 3gpp defined networks. I am posting a link including some specs related with this, in case you would like to check :

To much info in there. Honestly I don’t want to navigate through tons of 3GPP specs. Please, take a look to how audio codecs are defined in mediasoup here:

• https://github.com/versatica/mediasoup/blob/v3/src/supportedRtpCapabilities.ts#L5

And let’s know the exact new entry for AMR-WB audio codec. PR also welcome.

Right now the list of codecs supported by mediasoup are defined in the file above and also in C++ in:

• https://github.com/versatica/mediasoup/blob/v3/worker/include/RTC/RtpDictionaries.hpp#L46
• https://github.com/versatica/mediasoup/blob/v3/worker/src/RTC/RtpDictionaries/RtpCodecMimeType.cpp#L24
