Video codecs are plugins (external libraries) and H.263 and H.264 have dependencies that are required before they will build.

H.261

No dependencies. Make sure your copy the plugin to the same directory (or subDir) as the executable or set the PTLIBPLUGINDIR environmental variable to point to where the *plugin.so resides.

H.263

Dependency FFMPEG

for debian based systems

sudo apt-get install libavcodec-dev libavformat-dev libavcodec-dev

Goto H.261

H.264

Dependency FFMPEG (decode) and X264 (encode)

for debian based systems

sudo apt-get install libx264-dev

Goto H.263

Rerun ./configure and the codecs should then be available. Do a Make and the the *plugin.so should be in the h323plus/plugins directory. Copy them from there.

H.264 also has a *helper.so file which needs to be copied as well. This *MUST* be in the same directory as the executable. It does not understand the PTLIBPLUGINDIR environmental variable.

You should then be good to go.

To debug the codecs set the environmental variable PTLIB_TRACE_CODECS=4

You should see in the console the initial tests to check that all the dependencies are found at startup.

Hi everyone,

I’m having a lot of trouble setting up an OpenMCU server on either FreeBSD/Ubuntu (Ubuntu preferred).

On FreeBSD, after all the packages are installed I am seemingly limited to H.261 – The endpoints are capable of H.263/264, however I cannot get OpenMCU to use this codec.

On Ubuntu (my preferred system) OpenMCU preferences report the use of the G711 audio codecs, but do not even use the H.261 video codecs. There is no video output to any of the endpoints.

I think it might have to do with the codec installation on Ubuntu – How can I check if these are installed properly?

When I try to configure the h323plus install, I get the following:

There seem to be no video codecs being found or loaded… I’m running the latest version of everything from the h323plus.org site, OpenMCU 2.2.5-1, h323plus 1.23.0.

I’ve added what I believe to be the video codec directories in the following locations (yes, it’s a mess):

/usr/local/lib/opal-1.23.0/plugins/video

/usr/local/lib/opal-1.23.0/codecs/video

/usr/local/lib/opal-1.23.0/codecs/video/video

/usr/local/lib/opal-1.23.0/temp/plugins/video

/usr/local/lib/opal-1.23.0/video

/usr/lib/ptlib/plugins/video

/usr/lib/ptlib/codecs/video

/usr/lib/ptlib/video

/usr/lib/ptlib-2.4.5/plugins/video

The contents of these are:

root@OpenMCU:/usr/lib/ptlib/codecs/video# ls

common  H.261-vic  H.263-1998  H.263-ffmpeg  H.264

I’m also seemingly missing the H.264 codec:

configure: h264 support disabled due to disabled dependency HAVE_H264_DECODER

checking enable H.264 support... no

Can anyone shed some light on this?

Thanks!

Victor
