[Solved] Play just created movie

beginners
#1

Hi everybody,

I create a video mov file using ofxQtVideoSaver.
If I try to play the movie just after the saver.finishMovie() call, the application crash:

  
saver.finishMovie();  
ofVideoPlayer * player = new ofVideoPlayer();  
player->loadMovie("theMovie.mov"); // Crash!!!

I guess this is because the file isn’t “finalized” so quickly.

If I wait 2 seconds, and then try to load the movie, it work.
But I guess this delay may not fit all cases.
Do you know how can I check if the file creation is complete? Thank you very much.

(I’m working under Windows 7)

After some others tries, I see that my application can crash even if I wait 30 seconds before the loadMovie :frowning:

I try to detect if the file is available doing:

  
  
try {  
	fstream f (ofToDataPath(_file), ios::in | ios::out | ios::binary); // Open the file using the std lib  
	if (!f.is_open()) {       // check if it's possible to open the file  
		ofLogWarning("!f.is_open()"); // this message never appear  
		return;  
	}  
	if (!f.good()) {          // check if file is ready for read/write operations  
		f.close();  
		ofLogWarning("!f.good()"); // this message never appear  
		return;  
	}  
	f.close();  
	_content.loadMovie(_file);   // load the movie  
} catch (...) {  
	ofLogWarning("loading error");  // this message never appear. But the program crash.  
	return;  
}

I’ve got no ofLogWarning displayed, the program crash, the debugger say:

Program received signal SIGSEGV, Segmentation fault.

I solved my problem using ofxVideoRecorder instead of ofxQtVideoSaver.
