Frame lost, clicking sounds and jitter buffer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm running PJSIP 2.1.0 on an ARM platform and am experiencing various loud
clicking sounds (mostly) at the beginning of a call. The following is
printed in the log when the clicks occur:

09:24:46.628   strm0x8d1184  Frame lost, recovered!
09:24:46.629   strm0x8d1184  Jitter buffer starts returning normal frames
(after 1 empty/lost)

>From what I understand this is just adaptation of the jitterbuffer? (I have
no network packet-loss whatsoever.) It should be taken care of by the PLC,
and this actually does happen (I've checked that pjmedia_wsola_generate()
indeed is called when this happens), but nevertheless I get loud clicks.
The CPU load resides below 20% (according to "top") and I'm using the G722
codec. I have been trying various configuration changes (WSOLA/buffer sizes
etc.) to no avail. Any kind of help to get rid of the clicks is greatly
appreciated!

Regards,
Christian
