title: faild to build Libyuv library (PJSIP) for android
body: <p>I'm developing a chat android application. I want to use also the call functionality. I have successfully built the pjsua2.so library for SIP call VoIP but I failed to build Libyuv.so Library for video call</p>
  <p>I followed the instructions in thows to links
  <a href="https://trac.pjsip.org/repos/wiki/Getting-Started/Android#Requirements1" rel="nofollow noreferrer">libyuv building</a> <a href="https://trac.pjsip.org/repos/ticket/1776" rel="nofollow noreferrer">libyuv 1776</a></p>
  <p>After running ndk-build command in step 2 from the second link, I do not have this lib libyuv. So I don't have also [libyuv_dir]/libs/armeabi</p>
  <p>Also for openH264, after runnig this command <code>/configure-android --with-openh264=/home/ubuntu/openh264-1.0.0/android</code>  I got that :</p>
  <blockquote>
  <p>Using OpenH264 prefix... /home/ubuntu/PJSIPTOOLS/openh264-1.0.0/openlib/
  checking OpenH264 usability... no</p>
  </blockquote>
  <p>Can anybody help me please
  (sorry for bad english)</p>
