The reason why your codecs are loading and then unloading is that the codec
checks to see if all the dependencies are present and if they are not then
the codec is unloaded.

 

It is not clear on the platform you are running on but make sure you have
both x264 and FFMPEG  dependencies binaries are in path.

Using environmental variable PTLIB_TRACE_CODECS = 4 to output trace log
information on why the dependencies are not found.

Hi guys, 

 

I'm getting stuck with OpenMCU loading, and only starting the H.261 codecs. 

 

It seems it can detect H.263/H.264, but removes them shortly after
detection, and then only shows one set of codecs in the video section of the
startup.

Codecs loaded: 

 

     1:

       H.261-CIF{sw} <13>

 

I'm also seeing no split screen video - When new endpoints join, video on
the first endpoint freezes, and the new endpoint is not displayed until
either endpoint disconnects, then it switches back to whichever endpoint is
still connected and video resumes. 

 

Can anyone help? 

 

Thanks! 

 

Victor
