Video lags and out of sync with audio

Hi.
I hope that someone can help me with this.

Straight to the point: RPi 1B, minibian, OF0.9.0
Example videoPlayerExample works smooth. Replaced the fingers.mov with my own video and got a huge performance drop. Audio goes fine, but video is slow (about 10fps) or doesn't show at all (black rectangle). Sound ends much quicker then video. Removed all extra code so I'm left just with:

void ofApp::setup(){
	ofBackground(255,255,255);
	ofSetVerticalSync(true);
	fingerMovie.load("movies/s999_010.mov");
	fingerMovie.setLoopState(OF_LOOP_NORMAL);
	fingerMovie.play();
}

//--------------------------------------------------------------
void ofApp::update(){
    fingerMovie.update();
}

//--------------------------------------------------------------
void ofApp::draw(){
	ofSetHexColor(0x000000);
    fingerMovie.draw(100,20);
    ofDrawBitmapString(ofToString(ofGetFrameRate())+"fps", 20, 20);
}

Toggled the ofSetVerticalSync() with no difference.
Added ofDrawBitmapString(ofToString(ofGetFrameRate())+"fps", 20, 20); to try troubleshoot it, but even with the failing video I get 59-60fps of the app at all time or even 110-140 with ofSetVerticalSync(false).
