Re: [h323plus] Adding H263 codec to openmcu
Hi Jan,

Are you able to supply me with your patched ffmpeg 0.4.7 so I can continue with my current compilation with gcc 4.3, albeit an inelegant solution?
I'd like to learn how the openmcu works with your fantastic gnugk before the day is over.

Thanks Prasad,
I try install ffmpeg 0.4.7 from http://www.voxgratia.org/bin/ffmpeg-0.4.7.tar.gz but I get the following:

But I proceed and continue to configure and make and make install the a/v pugins in the ~/h323plus/plugins directory.
I create a directory ~/codecs and copy both h263-ffmpeg_video_pwplugin.so and libavcodec.so (from the libavcodec-0.4.7-linux.bin.tar.gz file) into there. I rename libavcodec.so to avcodec
I set export P_T_LIBPLUGINDIR=~/codecs (does this have to be P_W_LIBPLUGINDIR ?????)
I run openmcu and connect with Polycom PVX, and I see the video window!! But the video has strange lines with pink and blue colours, but it is the video from the webcam!
I assume it may be because I do not have the ffmpeg 0.4.7 installed correctly?
I will have a look at installing ffmpeg 0.4.7 direct from ffmpeg site.
So I am closer....
Thanks again for the help.

I compiled on a 64bit system. I would guess ffmpeg uses different assembler code on your 32bit system. I don't really want to get into supporting such an old ffmpeg version. I'm glad it works here and hope that Somon soon has the new version ready for a current ffmpeg.
