Hi Jan, I just copied and modified the wav_player.c and wav_writer.c and created two new ports in pjsip (raw_player.c, raw_writer.c). With these ports you are able to play and record from/to a named pipe (raw pcm data without a wave header). Maybe others will also find it useful, so I post it to the list. Just unpack the tar archive in pjproject-0.8.0. It will overwrite a Makefile and the playfile.c/recfile.c example to show how it works. Best regards, Marco ps: The functions can be much more improved and are poorly tested. I think it's a good "startpoint" to work with. _____ Von: pjsip-bounces at lists.pjsip.org [mailto:pjsip-bounces at lists.pjsip.org] Im Auftrag von jvdsandt Gesendet: Dienstag, 19.

I think it is possible to use pjsip/pjsau to stream a VoIP conversation as an mp3 stream without to much work. Unfortunately I am not a C programmer. I will look for someone who can help me to write the correct extension to pjsip/pjsua. Chhers, Jan.

Just find if (file_format == FMT_WAV) { status = pjmedia_wav_writer_port_create(pool, path, pjsua_var.media_cfg.clock_rate, pjsua_var.mconf_cfg.channel_count, pjsua_var.mconf_cfg.samples_per_frame, pjsua_var.mconf_cfg.bits_per_sample, options, 0, &port); in pjsua_media.c and add the following lines right after } else if (file_format == FMT_MP3) { status = pjmedia_mp3_writer_port_create(pjsua_var.pool, path, pjsua_var.media_cfg.clock_rate, pjsua_var.mconf_cfg.channel_count, pjsua_var.mconf_cfg.samples_per_frame, pjsua_var.mconf_cfg.bits_per_sample, enc_param, &port); ... and include mp3_writer.c and mp3_port.h to pjsua-lib project. This works for any pjsua-lib based applications.
