[opus] Question about PLC in OPUS

[Abhijit Patait]

I have a question about PLC used by OPUS.

We are using OPUS for streaming music in some application.

Due to some network problems, we are running into problems related to clock drifts. This causes jitter buffer underflows at the receiver and hence we need to rebuffer the jitter buffer periodically. We are looking at the root cause of this problem (drift), but that's besides the point.

During jitter buffer rebuffering, we are sending null frames to the OPUS decode, indicating lost frames. My question is - Is this the most effective way of handling this situation?

Or is it a better to detect such imminent underflow by some means and then insert "lost" frames in the middle sporadically to avoid the complete jitter buffer underflow?

Thanks for your help,
Abhijit
