Well, my ears aren't really
Hi again,
Here is the other codec I added for my bluetooth needs: aptX.
This one is based on my reverse engineering and my understanding
of patent EP0398973B1 (long expired).
[PATCH 1/2] aptx: implement the aptX bluetooth codec
[PATCH 2/2] aptx: add raw muxer and demuxer for aptX

Hello everyone,
Long time no see !
I'm glad to see ffmpeg still strong.
I'm curently playing with bluetooth audio (A2DP) and I wanted to
use lavc to do the encoding/decoding, so I added some codecs that
I need to ffmpeg.
Here is the result for the SBC codec.
[PATCH 1/3] sbc: implement SBC code
