openmcu hangs when second client accepts invitation
by Sander 29 Mar '10

29 Mar '10

Dear all, I'm trying to do a three-way videoconferencing with openmcu. After inviting two ekiga clients to the same conference room (from within the webinterface), openmcu hangs. Hangs means: http://10.0.0.1:1420/Status doesn't refresh anymore (reload times out eventually) and openmcu has to be killed with -9. When inviting the first ekiga client, the client sees the openmcu logo as 'remote video', and that client gets listed on the status page. When inviting the second ekiga client to the same room, that client sees it's own video, and 'remote video' is grayed out. If the second client is invited to a different room from the first instead, both clients see the openmcu logo (and openmcu doens't hang and the status page gets refreshed with both clients listed in their rooms). This all happened back in early february too. Now I found the time to try again. I've read al mails in the archive at http://lists.packetizer.com/pipermail/h323plus/ from november 2009 till now, but didn't find a similar case. The system on which all software is compiled and which is running openmcu, is an up to date Debian Sid (unstable) amd64, and selfcompiled kernel 2.6.32-rc6. The clients are a Debian Sid on Intel Core2 Duo and a Debian Sid on ARM (SheevaPlug). How can I debug what happens to openmcu? Or is there an obvious mistake in the steps below? With kind regards, Sander # ldd `which openmcu` linux-vdso.so.1 => (0x00007fff1f1ff000) libh323_linux_x86_64_.so.1.22.0 => /usr/local/h323plus/lib/libh323_linux_x86_64_.so.1.22.0 (0x00007eff1581c000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007eff15606000) libpt.so.2.9-beta0 => /usr/local/ptlib/lib/libpt.so.2.9-beta0 (0x00007eff150c8000) libpthread.so.0 => /lib/libpthread.so.0 (0x00007eff14eac000) librt.so.1 => /lib/librt.so.1 (0x00007eff14ca4000) libexpat.so.1 => /usr/lib/libexpat.so.1 (0x00007eff14a7b000) libdl.so.2 => /lib/libdl.so.2 (0x00007eff14877000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007eff14563000) libm.so.6 => /lib/libm.so.6 (0x00007eff142e0000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007eff140ca000) libc.so.6 => /lib/libc.so.6 (0x00007eff13d76000) /lib64/ld-linux-x86-64.so.2 (0x00007eff16278000) http://10.0.0.1:1420/Status (one client): Room Name Room Members Name Duration Codec RTP Packets/Bytes tx RTP Packets/Bytes rx TX Video frame rate/RX Video frame rate conference Sander 2:07.003 G.711-ALaw-64k/G.711-ALaw-64k 6350/1016000 6391/1022560 10.0007/9.68926 H.261-CIF/H.261-CIF The steps: svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg cvs -d:pserver:anonymous@h323plus.cvs.sourceforge.net:/cvsroot/h323plus login cvs -z3 -d:pserver:anonymous@h323plus.cvs.sourceforge.net:/cvsroot/h323plus co h323plus cvs -z3 -d:pserver:anonymous@h323plus.cvs.sourceforge.net:/cvsroot/h323plus co applications svn co http://opalvoip.svn.sourceforge.net/svnroot/opalvoip/ptlib/trunk ptlib svn co http://opalvoip.svn.sourceforge.net/svnroot/opalvoip/opal/trunk opal wget ftp://ftp.videolan.org/pub/videolan/x264/snapshots/x264-snapshot-20100315-2… tar jcf ptlib.tar.bz2 ptlib & tar jcf opal.tar.bz2 opal & tar jcf h323plus.tar.bz2 h323plus & tar jcf extensions.tar.bz2 extensions & tar jcf applications.tar.bz2 applications & tar jcf ffmpeg.tar.bz2 ffmpeg & export PKG_CONFIG_PATH=/usr/local/ffmpeg/lib/pkgconfig:/usr/local/ptlib/lib/pkgconfig export LD_LIBRARY_PATH=/usr/local/ffmpeg/lib:/usr/local/ptlib/lib export PTLIBDIR=/usr/src/h323/ptlib export OPENH323DIR=/usr/src/h323/h323plus export PTLIBPLUGINDIR=/usr/local/ptlib/lib/pwlib cd /usr/src/h323 tar xf x264-snapshot-20100315-2245.tar.bz2 cd x264-snapshot-20100315-2245 ./configure --enable-shared > /dev/null && \ make -j4 > /dev/null && \ make install > /dev/null cd /usr/src/h323 tar xf ffmpeg.tar.bz2 cd ffmpeg ./configure --prefix=/usr/local/ffmpeg --enable-shared --enable-libx264 \ --enable-libtheora --enable-libvorbis --enable-gpl --enable-decoder=h263 \ --enable-decoder=h263i --enable-decoder=h264 --enable-decoder=theora \ --enable-encoder=h263 --enable-encoder=h263p --enable-encoder=libx264 \ --enable-encoder=libtheora && \ make -j4 > /dev/null && \ make install > /dev/null ldconfig cd /usr/src/h323 tar xf ptlib.tar.bz2 cd ptlib export PTLIBDIR=/usr/src/h323/ptlib ./configure --prefix=/usr/local/ptlib && \ make -j4 > /dev/null && \ make install > /dev/null cd /usr/src/h323 tar xf h323plus.tar.bz2 cd h323plus ./configure --prefix=/usr/local/h323plus && \ make -j4 > /dev/null && \ make install > /dev/null cd /usr/local/include ln -s /usr/local/ffmpeg/include/libavcodec/ ffmpeg cd /usr/src/h323 cd extensions/plugins ./configure --prefix=/usr/local/ptlib && \ make -j4 > /dev/null && \ make install > /dev/null cp -a /usr/local/ptlib/lib/pwlib /usr/local/ cd /usr/src/h323 tar xf applications.tar.bz2 cd applications/openmcu/ make -j4 > /dev/null && \ make install > /dev/null /etc/ld.so.conf.d/openmcu.conf: /usr/local/h323plus/lib cd /usr/local/ptlib/lib/pwlib/ ln -s /usr/local/ffmpeg/lib/libavcodec.so ldconfig cd /bin/openmcu -d -- Humilis IT Services and Solutions http://www.humilis.net

H264 PLUGIN in H323Plus
by ooi khai chin 19 Mar '10

19 Mar '10

Hi All, In my latest status, I able to have the conference with polycom and other softphone using H.264 plugin. But I face the problem of delaying (my movement only show on the other endpoint after around 5 seconds in local network). I think this problem occur because of fragmentation of 1 encoded picture that has size greater than 1.4KB to multiple slices, then sent it out. Currently, my default frame rate is 10fps. My question is how to solve the delaying problem because I see polycom PVX 8.0.2 and other softphone do not have any delay? Another question, If my default frame rate is 10fps, is it means that my program will call Codec Encode function 10 times in a second? As I know, inside the encode function, every time it will check for remanding frame length for last packet, if exist it repeatably packet it with size less than 1.4KB until finish, then it only start to encode a new frame. So, Let say I have one encoded picture that consist of 10 slices, is it means that I only able to sent one complete picture in 1 second (if my fps=10)? Thanks.
