I detect a problem with the conference facility in pjmedia. In a slow/old machine, when the CPU is working in another process (something hard like opening a browser or another big program) the conference process stop its execution. How to test: First, enable the #define CONF_DEBUG in conference.c and build. Second, start in a terminal (I use gnome-terminal) the pjproject-1.14/pjsip-apps/bin/samples/i686-pc-linux-gnu/confsample program. Then, you will see a lot of debug lines, make a long click or try to select some text in the terminal to stop/delay execution. At least in my machine, the program still works with no hangs, but the conference stop and the get_frame() is never called again. Same effect opening something like Firefox, OpenOffice, etc. during conference execution. Thank you. Regards. -- ------------------------------------------------------------------------ Fabio E.
