I think I know my problem. If I queue all VLC buffers, I have a queue
that can vary between 60 and 65 buffers (on the sample/device I tested).
A difference of 5 buffers may be too big. Indeed, it means that my delay
can vary between 1600ms and 17200ms (for this example). I think that's
what provoke the up and down sampling.
Having a limit of 15 buffers allow to have a smaller difference of
buffers queued and then a smaller delay gap, but it's not a good
solution, the problem can still happen.
