Good day, All!
pjsip-2.0-RC much more reliable then beta.
BTW I can successfully make video call with resolution HD(1280x720),
1680x1050 , etc. It works. Also I have to do first 3-5 frames as I-Frames
to reach video rapidly after start video call.
The fix looks like(method ffmpeg_codec_encode_whole)- using global
counter m_first_frame_counter :
...
if (opt && opt->force_keyframe) {
...
//we set I-Frame all first 4 frames of video stream
if (m_first_frame_counter < 4)
{
avframe.pict_type = AV_PICTURE_TYPE_I;
m_first_frame_counter++;
}else
{
m_first_frame_counter = 4;
}
...
av_init_packet(&avpacket);
So, closer to my problem, my question: is it possible to change video
resolution directly during video call making? for example I do video call
with resolution 800x600 and, directly in call, I change output video to
1024x768.
Is it possible?
How can I do that in right way?
As I can see from pjsua_app.c code:
--------------------------------------------
} else if (argc==6 && strcmp(argv[2], "size")==0) {
pjmedia_vid_codec_param cp;
pj_str_t cid;
int M, N;
cid = pj_str(argv[3]);
M = atoi(argv[4]);
N = atoi(argv[5]);
status = pjsua_vid_codec_get_param(&cid, &cp);
if (status == PJ_SUCCESS) {
cp.enc_fmt.det.vid.size.w = M;
cp.enc_fmt.det.vid.size.h = N;
status = pjsua_vid_codec_set_param(&cid, &cp);
}
--------------------------------------------
we should get codec, change it properties and set it back.
but then I do:
status = pjsua_vid_codec_get_param(&codec_id, ¶m);
I have an assertion:
pj_assert(!"Calling pjlib from unknown/external thread. You must "
"register external threads with pj_thread_register() "
"before calling any pjlib functions.");
}
call stack:

That I do in wrong way? How can I do this correct?
Thank you!
