Hello all,

I'm trying to compile OpenAM and use the plugins from the plugins dir of h323plus. I've downloaded the latest ptlib, h323plus core and applications from http://www.h323plus.org/source/.

I started with a virgin install of Ubuntu 10.04 and installed dependent libs as necessary. Which version of ffmpeg works best with the plugins? apt-get retrieves ffmpeg 0.5.1. everything compiles fine and when I point PWLIBPLUGINDIR to OPENH323DIR/plugins openam lists all the codecs I expect to see - including H263. However, when I connect my video endpoint to it the video is freezes on what appears to be the first frame.

I've tried later versions of ffmpeg from ffmpeg.org and libav from libav.org (recompiling h323plus, the plugins and openam after each ffmpeg change) but then openam doesn't list H263 in its list of codecs - only H261. The configure script indicates libavcodec and h263 is available for every combination I've tried.

So, what's the secret to building openam with the H263 codecs? What version of ffmpeg must I use? Any help is greatly appreciated!

PS: my apologies for first accidentally sending this to open323gk-users.

Thanks! -Ben
