Hi All, I would like to decode AAC payload from A2DP packets, and feed AAC data into AAC audio decoder to output audio, ie, Bluetooth speaker function supporting AAC streaming. I have found there are sbc_decode() source code in pulseaudio-2.1, but I cannot find aac_decode(). Could all of you tell me how to get the aac_decode() source code and related application in the internet? Thanks a lot.
I don't think AAC is royalty-free so you probably need to get a license first, you could use a Open Source implementation like ffmpeg but that doesn't mean you will be able to distribute it (see https://en.wikipedia.org/wiki/Advanced_Audio_Coding#Licensing_and_patents). *OPUS would probably be much easier to be supported by pulseaudio since it royalty-free (see: https://www.opus-codec.org/license/) -- Luiz Augusto von Dentz
