Hello everybody, I'm a new member and I'm currently developing an application that requires video\audio calls. I'm trying to use PJSIP which seems to be a really great project. I've compiled the source code and I've started the pjsua tool. Audio calls work perfectly but I've some problems using video call. In particular I haven't been able to compile the pjsip source with support for H.264 video. Currently it shows only H.263 codec. I've followed the instructions reported in the trac: http://trac.pjsip.org/repos/wiki/Getting-Started/Autoconf So this is what I did: - installed SDL 2.0 (from sources) - installed ffmpeg library (from sources) - installed libx264 (from ubuntu repositories) - enabled the flag PJMEDIA_HAD_VIDEO (which enables the vid command in pjsua) After that I ran the configuration with the flags reported in the getting started. I compiled and started the pjsua tool, however the vid codec list command shows only the H.263 codec. I have no idea what I did wrong. Thank you for your help Federico.
