High CPU usage

Added by Josu Lazkano over 8 years ago

Hello all,

I have some problems with CPU usage in my Debian server.

I installed from this repository:

deb https://dl.bintray.com/tvheadend/deb jessie unstable

If I stream a single channel I have high CPU in the server:

I am using "Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz" proccesor.

How could I debug it?

Where could I see the tvheadened log?

Thanks for your help.

Kins regards.

libav indicates that your doing transcoding and on an old CPU it's to be expected..

RE: High CPU usage - Added by Josu Lazkano over 8 years ago

Thanks!

Is there any hardware to make transcode without CPU power?

Kind regards.
