[asterisk-app-dev] ARI Snoop Channel CPU Usage

[George Ladoff]

Didn't have a lot of luck frame copying directly from the channel. I
imagine it has something to do with not being able to actually answer the
spyee channel in snoop for blocking reasons.

Can I trouble you for one more clue: might extending Snoop with the
Framehook API be an option? And then I imagine creating some sort of frame
buffer (similar to the Audiohook's slin buffer) that snoop_read accesses at
the same/similar interval internal?

Please forgive me if I'm overextending the purpose of this list, I'm newish
to the world of Asterisk development at the source level and having a time
just getting used to some of the general "givens" of the environment.

Also, FWIW, when I stripped out the Audiohook references from the Snoop
driver, the CPU issue stopped showing up.
