[h323plus] Opal H.264 plugin with OpenMCU and H323plus

Hi,

I have taken latest code for ptlib, h323plus, avplugins from h323plus and H.264 plugin from opal.

I manged to have video call on OpenMCU with H263. I found it has dependency on specific version of libavcoded, 0.4.7.

For H264 I compiled the code and put the .so in $PWLIBPLUGINDIR, also I put libx264 in $LD_LIBRARY_PATH. But somehow H.264 codec is not getting loaded. The libraries are getting linked on start of openmcu but I cant see capabilities being added in OpenMCU traces.

Is there any specific version of libx264 needed? I tried with version 78 and 67. Also, H264 requires avcoded too. Is this needed to be built with option --enable-libx264 ?
