Hi, I am building an ffmpeg-based audio sink system to use a Raspberry Pi as a bluetooth speaker. Since the audio takes quite a long time to get past the processing on the Pi, I need to tell the bluetooth "client" device how much delay should be added (eg. for video playback) for it to be in sync. I've looked at the code and it looks like it's fully supported, but I don't understand how to signal bluez (running a2dp sbc sink profile) an extra latency for the source device to be aware. Can anyone help?
