videoPlayer GST isPaused isPlaying fix

[dimitre]

Changes in isPlaying() and isPaused() for uniformity in different platforms, as discussed here

• ofVideoPlayer isPlaying(), different behavior on ofVideoPlayer with or without Gstreamer #6527

Hey @ofTheo here is the PR for GStreamer Linux
I don't have my linux box working to test it so it would be great if somebody else could review and test the changes.

If anybody has Linux and a little time to test this PR here is one sample test:
press key:
a to play,
s to pause,
d to stop

if everything is OK the program should print the result of isplaying is paused
1, 0 for play
0, 1 for pause
0, 0 for stop.

#pragma once
#include "ofMain.h"

class ofApp : public ofBaseApp{
	public:

	ofVideoPlayer video;
	ofRectangle rect;

	void setup(){
		video.load("/Users/z/Desktop/WERK2022/Elka/Elka.mov");
		video.play();
	}

	void update(){
		if (video.isLoaded()) {
			video.update();
		}
	}

	void draw(){
		if (video.isLoaded()) {
			ofSetColor(255);
			video.draw(0,0,video.getWidth() * .5, video.getHeight() * .5);
			string msg;
			msg += "isPlaying() " + ofToString(video.isPlaying()) + "\n";
			msg += "isPaused() " + ofToString(video.isPaused());
			ofDrawBitmapString(msg, 40,40);
		}
	}

	void keyPressed(int key) {
		if (key == 'a') {
			video.play();
		}
		
		if (key == 's') {
			video.setPaused(true);
		}
		if (key == 'd') {
			video.stop();
		}
	}
};

Hello, I just tested on Ubuntu 20.04. There is a typo here
https://github.com/openframeworks/openFrameworks/pull/6987/files
pPaused should be bPaused on line 353.
Once that was corrected it functioned as expected.

• play(): isPlaying(): true isPaused(): false
• setPaused(true): isPlaying(): false isPaused(): true
• stop(): isPlaying(): false isPaused(): false
