I use pjmedia_port_info_init to create a player port. Something like
this:
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.
