Romain Beauxis commented on LS-520:
-----------------------------------
I have though about this in the paste and I think its an difficult topic, as
David described. However, I'd be curious to see if such algorithm is feasible.
I would, however, suggest to take a conservative approach: these issues affect
relatively few broadcasters, thus it is important to maintain a functional
harbor for the other.
Therefore, making it optional and disabled by default would be a good first
step.
Secondly, from Solvik's experience, the drift seems to be pretty constant for a
given situation. Thus, maybe it could be implemented with a fixed value for the
correction, which the user would chose according to its own context.
In this case, it could even be combined very nicely with
on_connect/on_disconnect the following way:
* Export a function allowing to set the drifting/lagging countereffect
parameter
* Document how to identify a broadcaster, either in on_connect or in auth and
how to set the correct value accordingly
> Deal linearly with drifting

> I think I have a simple idea to deal with drifting: if the client streams
> data too fast we could drop a sample once in a while, and if the client is
> too slow we could duplicate a sample once in a while. If the drift is not too
> important, it won't be audible. And the implementation is simple: it's just a
> matter of scaling linearly the buffer.

> PS: from what I understand, this should be dont by improving Generated
