Review request for Asterisk Developers.
Bugs: ASTERISK-20696 and ASTERISK-23836
https://issues.asterisk.org/jira/browse/ASTERISK-20696
https://issues.asterisk.org/jira/browse/ASTERISK-23836
Repository: Asterisk
Description
-------
Target: app_jack.c
Enables the jack-audiohook to cope with dynamic sampling rates from and to
Asterisk.
Information from channel is taken to derive the channel's sampling rate,
suiting SLINxx format and frame->datalen.
Limitations:
* Required information is taken from channel during initialization as audiohook
does not provide this information then. Audiohook.internal_sampl_rate(...) is
set later, but no callback is available to inform app_jack.
* Frame.datalen is computed using "rate / 50" assuming a ptime of 20ms.
There is no internal API available to determine datalen for a SLINxx.
* Ringbuffer size is a DEFINE and thus must be quite big to be able to cope
with 16Khz+
