I am trying to use libjitsi to stream some audio, but I can't get it to work. I'm on Windows 10. Here's what I've done:




  1. Clone https://github.com/jitsi/libjitsi.git

  2. Import into Eclipse as a Maven project. Everything compiles fine.

  3. I eventually realized (by looking at the Ant buildfile) that I needed some native libs, so I added the libs in /lib/native to the java.library.path.

  4. I am running AVTransmit2 with --local-port-base=5100 --remote-host=localhost --remote-port-base=5200 and AVReceive2 with --local-port-base=5200 --remote-host=localhost --remote-port-base=5100.


When I run either file, I get a similar error. First I see

and then later in the logs I see

Since I saw “ffmpeg” in the unsatisfied link error, I tried downloading ffmpeg from https://ffmpeg.zeranoe.com/builds/win64/shared/ffmpeg-4.1-win64-shared.zip. I chose the “shared” one because it has DLLs that I thought were needed to link the JNI interfaces to. I added the bin folder of the ffmpeg installtion to the java.library.path, but no joy - same error. It doesn't seem that any of their installers "install" anything - they just unzip files to the disk.



From the error stack, I’m guessing that somehow I’m missing some native libraries that are needed for DirectShow, but I cannot figure out what they should be.



Has anyone been able to get those examples to run? Is there something I need to install to get it working?

          Apparently there was something preventing the video media streams from initializing on every laptop I tried. But the audio streams were fine. By adding



          if(mediaType != MediaType.AUDIO) continue;


          inside the MediaType loop (using only AUDIO), I was able to get the example to work.
