<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using calling functionality with rtp. But I am facing issue related to echo when the call is ongoing.<o:p></o:p></p>
<p class="MsoNormal">To prevent this I added feature push to talk on temporary basis.<o:p></o:p></p>
<p class="MsoNormal">But to get rid of it, I found that webrtcdsp with webrtcechoprobe is a good option.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So after integration in my C++ application when I run my app I am getting errors as below:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Courier New";color:black;mso-fareast-language:EN-IN">GST:: "No echo probe with name webrtcechoprobe0 found." 164<o:p></o:p></span></p>
<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Courier New";color:black;mso-fareast-language:EN-IN">GST:: "../../../gst-plugins-bad-1.12.4/ext/webrtcdsp/gstwebrtcdsp.cpp(523): gst_webrtc_dsp_start (): /GstPipeline:audio_tx/GstWebrtcDsp:audio_rtc_dsp"</span><span style="font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:EN-IN"><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">FYI : I have taken two gst elements for webrtcdsp & webrtcechoprobe but I think when I am linking them at that time I am getting error as above. I am using Gstreamer 1.12.4.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please suggest any resolution or example, because on the forum there is not any example related to webrtcdsp echo cancellation.<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-IN">Regards,<o:p></o:p></span></p>
