Loading ofVideoPlayer inside thread

I'm trying to load a video with ofVideoPlayer within an ofThread but it crashes when I try.

btw i'm not trying to make a threaded video player, I just want to load a video in a thread grab some frames from it and then process them.

This is my thread class

#pragma once


#include "ofThread.h"
#include "ofMain.h"


class ThreadedObject: public ofThread
{
public:
    
    /// Create a ThreadedObject and initialize the member
    /// variable in an initialization list.
    ThreadedObject()
    {
    }

    /// Start the thread.
    void start()
    {
        
        // Mutex blocking is set to true by default
        // It is rare that one would want to use startThread(false).
        startThread();
    }

    /// Signal the thread to stop.  After calling this method,
    /// isThreadRunning() will return false and the while loop will stop
    /// next time it has the chance to.
    void stop()
    {
        stopThread();
    }
    void threadedFunction()
    {
        
        ofVideoPlayer vid;
        vid.loadMovie("01.mov");
        
        vid.play();
    
    }
};

And this is how its being called:

#include "ofApp.h"

void ofApp::setup()
{
	
}

void ofApp::update()
{
}

void ofApp::draw()
{
    ofBackground(ofColor::black);
	ofSetColor(ofColor::white);

    
}

void ofApp::keyPressed(int key)
{
    if (key == 'a')
    {
        threadedObject.start();
    }
    else if (key == 's')
    {
        threadedObject.stop();
    }
}
