example-sender - corrupt video on Linux

[steeley]

In example-sender the OF video grabber gets corrupted and and sends a faulty image. Note the video grabber preview in the sender is also corrupted.

Maybe pixel type is wrong ?? This seems to be a workaround, but means a copy(??)

void ofApp::update(){
    camera_.update();
            if(camera_.isFrameNew()) {
        //video_.send(camera_.getPixels()); //video gets corrupted by this call on linux
        ofPixels pix = camera_.getPixels();
        video_.send(pix);
    }

}

corrupted image:

correct image:

ofxNDISendVideo sends frames async by default. Guessing from the situation, the pixels may be edited inside camera_ before NDI sends the frame. probably from another thread?

So your workaround is correct.
