Good day to All!
I solved issue with latency!
In fact, PJSIP streams to iPad SIP client video with FPS = 30 frames.
And iPad CPU cannot process all the frames.
I modified method enc_clock_cb:
//////////////////////////////////////////////////////////////////////////
g_counter++;
if (g_counter % 6 == 0) //default FPS is 30 frames -> we make 30/6 = 5 FPS
{
vidstream_cap_cb(vp->strm, vp, vp->frm_buf);
}
//////////////////////////////////////////////////////////////////////////
// vidstream_cap_cb(vp->strm, vp, vp->frm_buf);
I achaived FPS, supported by iPad.
I used iPad2. On
-FPS 30 frames iPad CPU usage was 60%;
-FPS 10 frames iPad CPU usage was 40%;
-FPS 5 frames iPad CPU usage was 30%.
iPad was 2 cores by 1GHz each of them.
FPS 10 and 5 frames satisfied iPad and me :-)
in normal state iPad is consuming up to 5 % of CPU.
Now I have ONLY ONE ISSUE: I have bad quality of video.
How can it might be fixed?
I made 3 types of screen shots from iPad:
bad quality

half good quality

good quality

How can I fix bad blocks on the frames?
Thank you!
