You can always replace the master port with your own loop, something like
this:
while (1) {
pjmedia_port_get_frame(mem_player, ..., frame);
pjmedia_port_put_frame(stream_port, ..., frame);
usleep(...);
}
And it should be easy to replace the mem_player with your driver:
while (1) {
read_from_driver(pcm);
frame.data = pcm;
frame.size = ..;
pjmedia_port_put_frame(stream_port, ..., frame);
usleep(...);
}
If your driver provides blocking interface then the usleep() above probably
is not necessary.
The recommended way to do this is to make pjmedia_port abstraction for your
driver, so then you can integrate it nicely with the rest of pjmedia
framework. You still have the option on whether to use the master port or to
do the loop manually as above.
