G722 codec

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

 



Is there a specific reason why the default codec ptime is 10ms but 2 frames
are used per packet to get to the 20ms?

For me that means that the encoding and decoding has to be done twice with
the half sample count.
Isn't it possible to set the PTIME to 20ms and frames_per_pkt = 1?

Involved lines of code:
pjmedia/src/pjmedia-codec/g722.c: line 41,43 and 295
