Speex dev - Oct 2012 - Is it possible to change the quality with encoding ?

Hi All,

Actually, the question is right on the topic.

Is it possible to change the quality while encoding ?

If the answer is yes, does the jitter buffer provides info about latency, e.g. :
if latency is too high, we lower down the quality, if the latency is okay, we
are raising the quality until latency rise up again...

Thank you for your help.

Yes, you can change the quality while encoding. You can get all kinds
of statistics from jitter buffer (number of packets stored, etc.) and
can adjust the quality based on that. Please note that jitter buffer
is on receiving side and adjusting the quality is on sender side, so
you need to communicate your measurements to the other side.

Hi Jozsef,

Thank you for your answer.

Yes I'm aware of that, I have implemented a control stream in order to
change quality...
