pjmedia_port_put_frame frame size

[Manuel Quinteiro <mquinteiro@xxxxxxxxx>]

Hello, 

I'm trying to send a RTP stream.

I have negotiated and sdp then created an stream and retrieved de port  with pjmedia_stream_create

My internal audio is originaly defined as:

baudrate = 44100

samples per frame = 554

bits per sample 16

So I've create a resample por with:

pjmedia_resample_port_create( pool, port,44100, PJMEDIA_RESAMPLE_USE_LINEARPJMEDIA_RESAMPLE_USE_SMALL_FILTER|,&resample_port));

and sent the audio using

frame.size=554*2;

frame.buf=bufPt;  (bufPt is my frame with 554 samples)

rc=pjmedia_port_put_frame(resample_port,&frame);

Everything lucks ok but in the other side the audio is received distorted.

I've started to make different test and I have detect that I can't send my frame with 554 samples, that I have to send 20ms. (that is 882 samples)

What I'm doing wrong? I couldn't send the frame size that I want? If actually I have to send a predefined frame size (or time size), how I get that size/time?

Thanks!!!

Best regards.
