[pulseaudio-discuss] [RFC v2 0/3] Add dynamic configuration of SBC bitpool

[Frédéric Danis]

This series of patch allows to manage the bandwidth used by an A2DP source
using SBC encoder by adding ability to change the bitpool dynamically during
runtime.
In a crowded environment this can allow to limit interference between source
and headphones.
An external application should be able to control the SBC bitrate of up
to 300 BT transmitters in a noisy and possibly RF perturbed environment, for
which it can get the statistics for dropouts, and if it gets too high,
reduce the quality either globally, or across a physically-adjacent set of
transmitters.

This needs "Message API v2" patches from Georg Chini [1]

I am currently not sure in patch 2 where should occur the SBC bitpool apply.

Since V1:
- Added patch 3 to expose number of bytes skipped for the A2DP connection.

Any comments appreciated.
