A video player app, with demo expired licence???

Hi everyone :smiley:

I’m new in oF, and C++…

I have a little question, I could not find anything in the forum related to that…

I’m doing some exercises, like a simple video player:

void videoApp::setup(){  
	ofBackground(255, 255, 255);  
	screenHeight = float(ofGetScreenHeight());  
	isPaused = false;  

but when compile and run the code, in the app window appears in video:
“demo expired, 3ivx trial”, like in quicktime player 7…
(in the file attached)

is there any way to remove it, or i need to buy quicktime licence?

OF uses the Quicktime library which is also used by the quicktime player. This library as well as every other video player uses codecs like 3ivx to encode the video. A codec is almost an application itself and 3ivx is not a free one. So you’d have to buy a licence for it or do an uninstall and try another one. I use Perian http://perian.org/ for example.
