Of 0.10.1, osx 10.13.6, xcode 9.2.

Receiver does not see sender. sender works fine. NDI monitor app. shows video from sender correctly.

How can this be fixed?

TIA

nariakiiwatani commented 3 years ago

I'm not sure but please make these sure

installed latest NDI SDK
ofxNDI latest master branch without any change

Yes these things are ok. I tried the example router and this shows the source name from your sender example.

if I add: sources_ = ofxNDI::listSources(); in setup then the receiver examle seems to work, and shows the name of the sender.

Maybe something is broken with finder_.watchSources() ??

nariakiiwatani commented 3 years ago

to make things clear, please check following.

add a break point at line 32 of ofxNDIFinder.cpp (a line of unsigned int num_sources=0;) and see you reach there or not.
if not, comment out continue; above the breakpoint, and see value of num_sources after NDIlib_find_get_current_sources.
if num_sources remains 0 for a long time, do NDIlib_find_wait_for_sources with longer wait time. about 10000 or 50000? not sure

I have tried what you suggested, but num_sources is always zero. But changing setup() makes it work as I mentioned:

void ofApp::setup(){
    NDIlib_initialize();
    ofBackground(0);
    ofSetFrameRate(60);
    finder_.watchSources();
   // uncomment this line to make watchSources work
   // sources_ = ofxNDI::listSources();
}
