Loss Concealment

[kelchy]

Hi,

I noticed that this patch does not compensate for lost packets. May I know the reason why?
according to opus API, you should use opus_decode with null pointer when lost packets are detected.
Is this something not needed? will quality be improved if we do this?

Not sure we can figure out lost packets from within a codec plugin: all methods are invoked by the Asterisk core, and so we wouldn't be able to understand if and when a packet is lost.

Hi,

From what I understand, one of the major feature of Opus is PLC. Using this patch Asterisk/opus is not compensating for lost packet at all ? That mean a conversation with 1% packets loss using Opus will have the same quality than the same 1% packets loss with G711 for example ?
