Re: Reducing CPU usage with Gstreamer

Hello,

I think your audioconvert is the main culprit, either you find a way to not use it or optimize audioconvert.

I have wolfson pi with raspberry pi. I am able to stream audio over network with gstreamer library.

But problem is the CPU usage. It is taking almost 90% cpu usage. 

I am using following pipeline for this...

AUDIO SERVER

gst-launch alsasrc !  audioconvert ! audio/x-raw-int,channels=1,depth=16,width=16, rate=44100 ! rtpL16pay  ! udpsink host=127.0.0.1 port=5000

AUDIO CLIENT

gst-launch udpsrc port=5000 caps="application/x-rtp, media=(string)audio, clock-rate=(int)44100, width=(int)16, height=(int)16, encoding-name=(string)L16, encoding-params=(string)1, channels=(int)1, channel-position=(int)1, payload=(int)96" ! gstrtpjitterbuffer do-lost=true ! rtpL16depay ! audioconvert ! alsasink sync=false

Please let me know how to reduce CPU usage with this.

Thanks 

pirpi
