Hi

H.263,H.264 & MPEG4 requires the FFMPEG library and placed in the same directory as the plugin.

Hi, all.

I'm trying to set up an MCU server on SLES11 x64 with latest patches. I've grabbed the latest snapshots of ptlib and opal libraries (from http://opalvoip.svn.sourceforge.net) and latest h323plus and OpenMCU (from http://h323plus.cvs.sourceforge.net). After successful compilation with debug flags and a slight modification of Makefiles to repair "make install", I'a able to launch openmcu. But it gives messages like these in the startup log: ============ quote of openmcu startup ============= 2009/11/03 15:00:37.682 OpenMCU Debug2 H323 Found capability: H.261-QCIF{sw} <25> 2009/11/03 15:00:37.683 OpenMCU Debug2 H323 Removing capability: H.261-QCIF{sw} <25> 2009/11/03 15:00:37.684 OpenMCU Debug2 H323 Found capability: H.261{sw} <26> 2009/11/03 15:00:37.684 OpenMCU Debug2 H323 Removing capability: H.261{sw} <26> 2009/11/03 15:00:37.685 OpenMCU Debug2 H323 Found capability: H.263{sw} <27> 2009/11/03 15:00:37.686 OpenMCU Debug2 H323 Removing capability: H.263{sw} <27> 2009/11/03 15:00:37.687 OpenMCU Debug2 H323 Found capability: MPEG4{sw} <28> 2009/11/03 15:00:37.688 OpenMCU Debug2 H323 Removing capability: MPEG4{sw} <28> ============ end of quote of openmcu startup ============= And when the final codec list is printed, it looks like this: ============ quote of openmcu startup ============= 1: H.261-CIF{sw} <24> 2: ============ end of quote of openmcu startup ============= And like the last message shows, OpenMCU doesn't use h263 and MPEG-4 codecs, only H.261 Codecs for H.264 are compiled too and placed just near the other (h261,h263) codecs, but aren't even being noticed by openmcu. I've tried both with h323plus/plugins and opal/plugins by creating symlinks to their ".so" files in "/usr/local/lib/ptlib" directory. The same result, though many audio codecs from opal are being successfully loaded.

The questions are: 1. Why openmcu removes capabilities that were successfuly found? 2. Why openmcu doesn't load plugins in the plugin dir?

Thanks for any response. Tell me, if any additional info is required.
