i have 2 mp4 videos playing on screen, , both of them supposed loop. both reset @ same time, when 1 ends. how adjust code videos loop separately?

    let videourl: nsurl = nsbundle.mainbundle().urlforresource("duda", withextension: "mp4")!     let sakeleurl: nsurl = nsbundle.mainbundle().urlforresource("sakele_blikas", withextension: "mp4")!       player = avplayer(url: videourl)     player?.actionatitemend = .none     player?.muted = true      player2 = avplayer(url: sakeleurl)     player2?.actionatitemend = .none     player2?.muted = true      let playerlayer = avplayerlayer(player: player)     playerlayer.videogravity = avlayervideogravityresizeaspectfill     playerlayer.zposition = -1      let playerlayer2 = avplayerlayer(player: player2)     playerlayer2.videogravity = avlayervideogravityresizeaspectfill     playerlayer2.zposition = -1        playerlayer.frame = cgrect(x: 50.0, y: 100.0, width: 240.0, height: 433.0)     playerlayer2.frame = cgrect(x:647.0, y: 90.0, width: 115.0, height: 44.0)      view.layer.addsublayer(playerlayer)     view.layer.addsublayer(playerlayer2)     player?.play()     player2?.play()      //loop video     nsnotificationcenter.defaultcenter().addobserver(self,         selector: "loopvideo",         name: avplayeritemdidplaytoendtimenotification,         object:nil)      nsnotificationcenter.defaultcenter().addobserver(self, selector: "loopvideo2", name: avplayeritemdidplaytoendtimenotification, object: nil)    } 

func loopvideo(notification: nsnotification) {

if let finishedplayer = notification.object as! avplayer! {     if finishedplayer == self.player2     {       self.player2?.seektotime(kcmtimezero)       self.player2?.play()     } else {       self.player?.seektotime(kcmtimezero)       self.player?.play()     } } 

}

heres error code not sure how format it

so have these 2 lines of code:

//loop video nsnotificationcenter.defaultcenter().addobserver(self,     selector: "loopvideo",     name: avplayeritemdidplaytoendtimenotification,     object:nil)  nsnotificationcenter.defaultcenter().addobserver(self,      selector: "loopvideo2",      name: avplayeritemdidplaytoendtimenotification,      object: nil) 

which registering 2 functions called exact same notification. you're not determining there video (or video player) has finished up.

but have way this.

the object passed along in avplayeritemdidplaytoendtimenotification notification "is item finished playing".

try doing:

func loopvideo(notification: nsnotification) {      if let finishedplayer = notification.object avplayer!     {         if finishedplayer == self.player2         {           self.player2?.seektotime(kcmtimezero)           self.player2?.play()         } else {           self.player1?.seektotime(kcmtimezero)           self.player1?.play()         }     } } 

for work, need make player1 , player2 properties of view controller (instead of local variables live in viewdidload or viewwillappear functions).
