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.
