Many thanks Benny, I followed your advice and gave a directory for the ffmpeg libraries using the --prefix ffmpeg option and then used the --with-ffmpeg pjsip configure option to tell pjsip build about the ffmpeg library locations. The pjsip build now completed without error. Of course I wanted to try some AVI files, but was not able to find any on the net. I saw a lot about avi converters, Xvid, MKV, VOB and other three-letter words, but nothing small with H263+avi or H264+avi suitable for testing. I am probably not looking the right way... Q1.? how can I get H263 and h264 avi files for testing?

"./src/pjmedia-codec/ffmpeg_vid_codecs.c:258:5: error: #error "Must use libavcodec version 53.20 or later to enable FFMPEG H264" The PCs here run the current Long-Term_Support (LTS) version 10.04 of Ubuntu and it is not possible to move away from that at the moment. Libavcodec53 is available for Ubuntu 12.04 and 11.10 but not for Ubuntu 10.04. I checked with Synaptic Manager and Software Centre on 10.04 and these do not show libavcodec53 as a choice, only libavcodec52. So libavcodec53 is not in the standard repositories of Ubuntu 10.04. Q1. can I obtain libavcodec53 et al in some other way? I believe I only need the libavxxxxs (what are they?), not the command-line ffmpeg (correct?) I am using 10.04 too, and I surely don't want to upgrade workstation because of pjsip either. :) The solution is easy though, just download the latest ffmpeg and configure/install it to a private directory using --prefix argument to configure, then use --with-ffmpeg option when running pjsip's configure to tell it where ffmpeg is. The same for SDL etc. ? Q2.? can I leave out the H264 video and still experiment to get a feel for how to use pjsip with video, for example by using H263? I notice pjsip also supports AVI. Is that available without H264? Sure. For AVI, we support decoding few more codecs such as MJPEG. ? There is a macro PJMEDIA_HAS_FFMPEG_CODEC_H264 defined in pjmedia/include/pjmedia-codec/config.h and referenced in pjmedia-codec/ffmpeg_vid_codecs.c. Q3.? should I set PJMEDIA_HAS_FFMPEG_CODEC_H264 to 0 in config.h? Is that safe or are there better ways to force a build without H264 support? No. *Always* use config_site.h to override the settings. Have you not read the user's guide (I hope this is written there somewhere). :) ? Q4.? is it possible to build with H264 support using libavcodec52 i.e. by not using the very latest libavxxxs? Would that result in reduced h264 functionality say, or is it impossible? If possible, what do I need to do? ? See Q1. ?Benny ?
