ios - 快速将自定义控件添加到 AVPlayer

Question

我正在尝试创建一个表格 View 以便我能够播放视频。我可以使用 AVPlayer 和层来做到这一点。

我想在视频 View 的底部添加一个带有 slider 的自定义播放和暂停按钮。

AVPlayerController 内置了这些控件。

我如何在 AVPlayer 中实现这些。我一直在寻找例子。但是我还没有找到。

是否有任何我可以遵循的 GitHub 示例或代码示例？任何帮助将不胜感激。

Answer 1

这里我加点，大家可以根据自己的需要定制。

第一步

最初隐藏您的 AVPlayer 控件，

 YourAVPlayerViewController.showsPlaybackControls = false

第二步

创建如下结构

one label for current Duration, One label for overall Duration, one UIbutton for pause and play your current player and one UISlider for seek The video.

第三步

初步关闭简单的步骤。

first stop and play the player using button action , currentPlayer is your AVPlayer name.

@IBAction func handlePlayPauseButtonPressed(_ sender: UIButton) {
   //  sender.isSelected ?  currentPlayer.pause() :   currentPlayer.play()
    if sender.isSelected {
        currentPlayer.pause()
    }
    else {
        currentPlayer.play()
    }
}

second set the video duration, as like

    let duration : CMTime = currentPlayer.currentItem!.asset.duration
    let seconds : Float64 = CMTimeGetSeconds(duration)

    lblOverallDuration.text = self.stringFromTimeInterval(interval: seconds)

third set the player current time to current duration label

    let duration : CMTime = currentPlayer.currentTime()
    let seconds : Float64 = CMTimeGetSeconds(duration)

    lblcurrentText.text = self.stringFromTimeInterval(interval: seconds)

the following method is convert from NSTimeinterval to HH:MM:SS

func stringFromTimeInterval(interval: TimeInterval) -> String {

    let interval = Int(interval)
    let seconds = interval % 60
    let minutes = (interval / 60) % 60
    let hours = (interval / 3600)
    return String(format: "%02d:%02d:%02d", hours, minutes, seconds)
}

finally we go for slider control for calulate the seek time

_playheadSlider.addTarget(self, action: #selector(self.handlePlayheadSliderTouchBegin), for: .touchDown)
_playheadSlider.addTarget(self, action:    #selector(self.handlePlayheadSliderTouchEnd), for: .touchUpInside)
_playheadSlider.addTarget(self, action: #selector(self.handlePlayheadSliderTouchEnd), for: .touchUpOutside)
_playheadSlider.addTarget(self, action: #selector(self.handlePlayheadSliderValueChanged), for: .valueChanged)

lets we go for action, initially when touchbegin is start then stop the player

handlePlayheadSliderTouchBegin

@IBAction func handlePlayheadSliderTouchBegin(_ sender: UISlider) {
currentPlayer.pause()
}

set the current item label for calculate the sender.value * CMTimeGetSeconds(currentPlayer.currentItem.duration)

@IBAction func handlePlayheadSliderValueChanged(_ sender: UISlider) {

        let duration : CMTime = currentPlayer.currentItem!.asset.duration
     let seconds : Float64 = CMTimeGetSeconds(duration) * sender.value
 //   var newCurrentTime: TimeInterval = sender.value * CMTimeGetSeconds(currentPlayer.currentItem.duration)
lblcurrentText.text = self.stringFromTimeInterval(interval: seconds)
   }

finally move the player based on seek

 @IBAction func handlePlayheadSliderTouchEnd(_ sender: UISlider) {

  let duration : CMTime = currentPlayer.currentItem!.asset.duration
var newCurrentTime: TimeInterval = sender.value * CMTimeGetSeconds(duration)
var seekToTime: CMTime = CMTimeMakeWithSeconds(newCurrentTime, 600)
currentPlayer.seek(toTime: seekToTime)
}
