I'm using XCDYouTubeKit, written as a subclass of MPMoviePlayerViewController.
I'm having an issue playing the next video in my playlist. When I tap the forward button, the state of the player is stopped, and I'm not sure how to resume it?
Here's my code:
override func viewDidLoad()
{
super.viewDidLoad()
youtubeVideoPlayer = XCDYouTubeVideoPlayerViewController(videoIdentifier: videoID)
self.view.addSubview( (youtubeVideoPlayer?.view)! )
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "moviePlayerNowPlayingMovieDidChange:",
name: MPMoviePlayerNowPlayingMovieDidChangeNotification,
object: youtubeVideoPlayer?.moviePlayer)
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "moviePlayerLoadStateDidChange:",
name: MPMoviePlayerLoadStateDidChangeNotification,
object: youtubeVideoPlayer?.moviePlayer)
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "moviePlayerPlaybackDidChange:",
name: MPMoviePlayerPlaybackStateDidChangeNotification,
object: youtubeVideoPlayer?.moviePlayer)
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: "moviePlayerPlayBackDidFinish:",
name: MPMoviePlayerPlaybackDidFinishNotification,
object: youtubeVideoPlayer?.moviePlayer)
}
func moviePlayerPlayBackDidFinish(notification: NSNotification)
{
print("moviePlayerPlayBackDidFinish")
youtubeVideoPlayer!.view.removeFromSuperview()
self.dismissViewControllerAnimated(true, completion: nil);
}
func moviePlayerNowPlayingMovieDidChange(notification: NSNotification)
{
print("moviePlayerNowPlayingMovieDidChange")
}
func moviePlayerLoadStateDidChange(notification: NSNotification)
{
print("moviePlayerLoadStateDidChange")
youtubeVideoPlayer?.moviePlayer.play()
let state: MPMoviePlaybackState = (youtubeVideoPlayer?.moviePlayer.playbackState)!
switch state
{
case MPMoviePlaybackState.Stopped:
print("stopped")
break
case MPMoviePlaybackState.Interrupted:
print("interrupted")
break
case MPMoviePlaybackState.SeekingForward:
print("forward")
break
case MPMoviePlaybackState.SeekingBackward:
print("backward")
break
case MPMoviePlaybackState.Paused:
print("paused")
break
case MPMoviePlaybackState.Playing:
print("playing")
break
}
}
func moviePlayerPlaybackDidChange(notification: NSNotification)
{
print("moviePlayerPlaybackDidChange")
let state: MPMoviePlaybackState = (youtubeVideoPlayer?.moviePlayer.playbackState)!
switch state
{
case MPMoviePlaybackState.Stopped:
print("stopped")
videoIDIndex = videoIDIndex + 1
playNextVideo()
break
case MPMoviePlaybackState.Interrupted:
print("interrupted")
break
case MPMoviePlaybackState.SeekingForward:
print("forward")
break
case MPMoviePlaybackState.SeekingBackward:
print("backward")
break
case MPMoviePlaybackState.Paused:
print("paused")
break
case MPMoviePlaybackState.Playing:
print("playing")
break
}
}
func playNextVideo()
{
if segueIdentifer == "SegueFromPlaylistVideos"
{
print("Playlist")
NSNotificationCenter.defaultCenter().removeObserver(
self,
name: MPMoviePlayerPlaybackDidFinishNotification,
object: youtubeVideoPlayer?.moviePlayer
)
print("videoIDs_ARRAY = \(videoIDs_ARRAY)")
print("videoIDs_ARRAY[videoIDIndex] = \( (videoIDs_ARRAY[videoIDIndex] as String) )")
youtubeVideoPlayer?.videoIdentifier = videoIDs_ARRAY[videoIDIndex] as String
}
}
The sequence are as follows when the first video is played in the playlist, and I tap the forward to move to the next video:
moviePlayerNowPlayingMovieDidChange
moviePlayerLoadStateDidChange
moviePlayerPlaybackDidChange
playing
playing
moviePlayerLoadStateDidChange
playing
moviePlayerPlaybackDidChange
stopped
Playlist
videoIDs_ARRAY = ["NztC0z1JNq0", "uqRBijuCZd8"]
videoIDs_ARRAY[videoIDIndex] = uqRBijuCZd8
moviePlayerLoadStateDidChange
stopped
As you can see at the end, the state of the player is stopped.
I'm not sure how to resume it so it will play the next video. I've tried to add youtubeVideoPlayer?.moviePlayer.play() within moviePlayerLoadStateDidChange but the player does not resume playing.
Any thoughts on this?
Thanks
I don't know syntax in Swift so please translate objective-c to swift
I have 2 solutions for you problem :-
1. You can stop current playing video syntax in objective-c like
[self.youtubeVideoPlayer.moviePlayer stop];
and then you can set new video
self.youtubeVideoPlayer.videoIdentifier=videoIdentifier;
self.youtubeVideoPlayer.moviePlayer.shouldAutoplay=TRUE;
[self.youtubeVideoPlayer presentInView:self.playerView];
[self.youtubeVideoPlayer.moviePlayer prepareToPlay];
self.youtubeVideoPlayer.moviePlayer.shouldAutoplay=TRUE;
2. You can do like this
set nil to your XCDYouTubeVideoPlayerViewController reference and set it again
self.youtubeVideoPlayer = nil;
self.youtubeVideoPlayer = [[XCDYouTubeVideoPlayerViewController alloc] init];
self.youtubeVideoPlayer.moviePlayer.shouldAutoplay=TRUE;
self.youtubeVideoPlayer.moviePlayer.controlStyle= MPMovieControlStyleNone;
self.youtubeVideoPlayer.moviePlayer.scalingMode = MPMovieScalingModeFill;
and then you can set new video
self.youtubeVideoPlayer.videoIdentifier=videoIdentifier;
self.youtubeVideoPlayer.moviePlayer.shouldAutoplay=TRUE;
[self.youtubeVideoPlayer presentInView:self.playerView];
[self.youtubeVideoPlayer.moviePlayer prepareToPlay];
self.youtubeVideoPlayer.moviePlayer.shouldAutoplay=TRUE;
Example: -
#import "ViewController.h"
#import "XCDYouTubeVideoPlayerViewController.h"
@interface ViewController ()
{
NSArray *urlArray;
int arrindex;
}
@property (weak, nonatomic) IBOutlet UIView *playerView;
@property (nonatomic, strong) XCDYouTubeVideoPlayerViewController *videoPlayerViewController;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
urlArray = [[NSArray alloc] initWithObjects:@"zVyEPNIR-yk",@"r5RXlY3at-E",@"sUFKakydp2c",@"1xvLHxFUwIk", nil];
arrindex = 0;
NSNotificationCenter *defaultCenter = [NSNotificationCenter defaultCenter];
[defaultCenter addObserver:self selector:@selector(moviePlayerPlaybackStateDidChange1:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:nil];
[defaultCenter addObserver:self selector:@selector(moviePlayerLoadStateDidChange1:) name:MPMoviePlayerLoadStateDidChangeNotification object:nil];
[self setVideo];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)setVideo
{
self.videoPlayerViewController = [[XCDYouTubeVideoPlayerViewController alloc] init];
self.videoPlayerViewController.moviePlayer.shouldAutoplay=TRUE;
self.videoPlayerViewController.moviePlayer.controlStyle= MPMovieControlStyleNone;
self.videoPlayerViewController.moviePlayer.scalingMode = MPMovieScalingModeFill;
[self.playerView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
NSString *videoIdentifier =[urlArray objectAtIndex:arrindex];
self.videoPlayerViewController.videoIdentifier=videoIdentifier;
self.videoPlayerViewController.moviePlayer.shouldAutoplay=TRUE;
[self.videoPlayerViewController presentInView:self.playerView];
[self.videoPlayerViewController.moviePlayer prepareToPlay];
self.videoPlayerViewController.moviePlayer.shouldAutoplay=TRUE;
}
- (IBAction)Next:(id)sender {
arrindex++;
if (arrindex<urlArray.count) {
self.videoPlayerViewController=nil;
[self setVideo];
}
}
- (void) moviePlayerLoadStateDidChange1:(NSNotification *)notification
{
MPMoviePlayerController *moviePlayerController = notification.object;
MPMovieLoadState state = moviePlayerController.loadState;
if (state & MPMovieLoadStatePlayable)
{
[self.videoPlayerViewController.moviePlayer play];
}
else if (state & MPMovieLoadStatePlaythroughOK)
{
}
else if (state & MPMovieLoadStateStalled)
{
}
}
- (void) moviePlayerPlaybackStateDidChange1:(NSNotification *)notification
{
long reason=(long)self.videoPlayerViewController.moviePlayer.playbackState;
if (reason==0)
{
NSLog(@"I'm Not Playing");
}
else if (reason==1)
{
NSLog(@"I'm Playingggggggggggggggg");
}
else if (reason ==2)
{
NSLog(@"pause....................................");
}
else if (reason ==3)
{
//NSLog(@"Interrupteddddddddddddddddd");
}
else if (reason ==4)
{
//NSLog(@"Seeking Forward");
}
else if (reason ==5)
{
//NSLog(@"Seeking Backward");
}
}
@end
I hope this helps you.
