Linux is a moving target.
Try it without libavcore. The codec will build. Enable codec tracing and
check if the codecs load properly.
I know libavcore is definitely required on some platforms and versions of
FFMPEG.

Hi Simon,
I've installed libavcodec-dev and libavformat-dev, but I can't seem to find
libavcore-dev for Ubuntu Oneiric... The closest I could find was
http://ftp.br.debian.org/debian-multimedia/pool/main/f/ffmpeg-dmo/libavcore-
dev_0.6.1+svn20101128-0.2squeeze2_i386.deb, would that work?

Sorry
It should be avcore-dev
So it should look like
sudo apt-get install libavcodec-dev libavformat-dev libavcore-dev
Thanks

Simon,
In the H.263 instructions, you list libavcodec-dev twice. Is that correct?
or is there a 3rd dependency?
thanks,

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:
=================== Plugin configuration ======================
prefix : /usr/local
exec_prefix : ${prefix}
libdir : ${exec_prefix}/lib
Audio Codec plugin install dir : ${libdir}/opal-1.23.0/codecs/audio

LID plugin install prefix : ${libdir}/opal-1.23.0/lid
FAX plugin install prefix : ${libdir}/opal-1.23.0/fax
GSM : yes (internal)
gsm-amr : yes
iLBC : yes (internal)
Speex : yes (internal, version 1.1.11.1)

G.726 : yes
IMA_ADPCM : yes

CELT : no
SpanDSP FAX : no

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 at 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
