Maybe useful for someone J
I made the following changes in stereo_port.c:
static pj_status_t stereo_get_frame(pjmedia_port *this_port,
pjmedia_frame *frame)
//tmp_frame.buf = sport->get_buf? sport->get_buf : frame->buf; //
allocate get buffer for stereo port ???
//tmp_frame.size = sport->dn_port->info.bytes_per_frame;
if (sport->get_buf)
{
tmp_frame.buf = sport->get_buf;
tmp_frame.size = sport->dn_port->info.bytes_per_frame;
}
else
{
tmp_frame.buf = frame->buf;
tmp_frame.size = frame->size; // da,

}
static pj_status_t stereo_put_frame(pjmedia_port *this_port,
const pjmedia_frame *frame)
//tmp_frame.size = sport->dn_port->info.bytes_per_frame;
tmp_frame.size = sport->dn_port->info.samples_per_frame //
da, 2009-06-30
* sport->base.info.bits_per_sample / 8;
Still have memory problems (heap) in relation with the stereo usage. But
stereo <-> G.711 seems ok now.

I'm trying to use pjmedia_stereo_port_create() resolve my problem. But I
ends at runtime with at this point:
g711_decode: Assertion `output_buf_len >= (input->size << 1)' failed.
The get_frame() function call the decoder with the following values:
outSize:0, frame->size:160, samples_count:80, BYTES_PER_SAMPLE:2
Is the stereo port a practicable way to solve my problem ?

Subject: G.711 with stereo hardware
Hi all,
I'm running PJSIP and PJMEDIA on a hardware that have some problems
with mono sound. Stereo works fine.
I have to use G.711 as audio codec. Is there an "easy" way to add a
second channel (ideally a copy) to the existing one ?
Best regards
David
