Thanks for your anwser Norman.
You are using a very diferent approach from mine. Could you provide some more information ( or some source code ) ?
My DirectShow sound reading routines are pushing audio frames that i need to send throw PJSIP.
So i need to call put_frame on a media port.
How did you created this "Passive" port ?
You also add it to the conference bridge, right ?
Thanks in advance...

pool = pjsua_pool_create("MyPlayerPool", 4000, 4000);
pj_strdup2(pool, &base.info.name, "MyPlayer");
base.get_frame = &file_get_frame_get;
base.put_frame = &file_put_frame_get;
base.on_destroy = &file_on_destroy_get;
pjmedia_port_info_init(&base.info, &name, SIGNATURE, sampling_rate, channel_count, bits_per_sample, samples_per_frame);
This works well for playing files in a non-standard format that I need to support. You put your sample generation code in file_get_frame_get.

Hi, i made a media player in DirectShow that captures PCM audio frames from mp3 audio files. I need to send this audio frames to PJSIP. Can anyone help me? I have tried adding a passive_port to the conference bridge and it did not worked. Now i am trying to use splitcomb. And i can send some noise. Here's a code sample: // 1? pjmedia_splitcom_createpj_status_t status = pjmedia_splitcomb_create(pool_vars, nSamplesPerSec, nChannels, samplesPerFrame, wBitsPerSample, 0, &p_splitcomb);// for each channelfor(unsigned int i = 0; i < nChannels; i++) { unsigned int p_slot; pjmedia_port* p_port; // 2? pjmedia_splitcom_create_rev_channel status = pjmedia_splitcomb_create_rev_channel(pool_vars, p_splitcomb, i, 0, &p_port); // 3? pjmedia_conf_add_port status = pjmedia_conf_add_port(conference_bridge, pool_vars, p_port, NULL, &p_slot);} And then, when i want to send an audio frame i do the following: pjmedia_port_put_frame(p_splitcomb, &frame); What is wrong with my code?Am i using splitcom correctly? Any help would be appreciated... Rafael Maia
