<div dir="ltr">I hear what you are saying and I agree. When I saw my CPU going through the roof I saw the job running as ad detection and when I disabled it my CPU went right down to normal. Strange. SO I have always thought this was a CPU intensive thing,. I noted the jobs ran after the recording completed and it redid those until I disabled the detection. Anyways I am happy enough to give it another go now as I am setting up new mythtv on 18.04. <br></div><div class="gmail_extra"><br><div class="gmail_quote">On 7 May 2018 at 15:19, Nick Rout <span dir="ltr"><<a href="mailto:nick.rout@gmail.com" target="_blank">nick.rout@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Silence detection is not CPU intensive as it involves no video decoding. <div><div class="h5"><br><div class="gmail_extra"><br><div class="gmail_quote">On Mon, May 7, 2018 at 2:59 PM, James Walker <span dir="ltr"><<a href="mailto:james.walker.nz@me.com" target="_blank">james.walker.nz@me.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word"><div><div>The tooling I have setup is per this wiki page:</div><div>https://<a href="http://www.mythtv.org/wiki/Commercial_detection_with_silences" target="_blank">www.mythtv.org/wiki/Co<wbr>mmercial_detection_with_silenc<wbr>es</a></div><div><br></div><div>The processing seems to be reasonably light weight and pretty fast.

I also changed my recording templates to turn off the option in there<br>
that creates the mythcommflag job, and used SQL to do the same in all<br>
my recording rules.<br>
