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

[George Ladoff]

Thanks Joshua. Will do. :)

On a similar note though, do snoop channels always transcode? I've noticed
that decoding or encoding (depending on snoop type) starts the moment I
start a snoop channel.

At first I thought this was what was causing the CPU usage but it doesn't
appear to be. The same transcoding will occur on recording and playback
(when necessary) and doesn't appear to have the same CPU overhead.

Maybe another way to put my question: is there any voodoo I can do to
prevent a snoop channel from transcoding, then only trigger a transcode
when needed (recording, playback, some bridges)? Or will it always
transcode (something about how snoop works)? Or have I encountered another
bug? ;)

Thanks again!
