我打算在播放hls流时获得视频分辨率.
我有典型的玩家init：
我有典型的玩家init：
let urlAsset = AVURLAsset(URL: currentVideoUrl) self.player=AVPlayer(playerItem: AVPlayerItem(asset:urlAsset)) .......
我使用KVO,我试图获得视频大小,当我得到.ReadyToPlay状态AVPlayerItem：
func resolutionSizeForVideo() {
guard let videoTrack = self.player.currentItem?.asset.tracksWithMediaType(AVMediaTypeVideo).first else
{ return
}
let size = CGSizeApplyAffineTransform(videoTrack.naturalSize,videoTrack.preferredTransform)
let frameSize = CGSize(width: fabs(size.width),height: fabs(size.height))
print ("video size: \(frameSize)")
}
问题是trackWithMediaType()总是返回空数组(但适用于非流文件,例如.mov).
如何获取AVPlayer内播放的HLS视频的大小(CGRect)？
解决方法
您是否能够使用此方法至少记录视频信息？
func checkVideoRez(videoURL: NSURL) -> Bool {
let videoAssetSource = AVAsset.init(URL: videoURL)
let videoTrack = videoAssetSource.tracksWithMediaType(AVMediaTypeVideo)[0]
let size = videoTrack.naturalSize
let txf = videoTrack.preferredTransform
let realVidSize = CGSizeApplyAffineTransform(size,txf)
print(videoTrack)
print(txf)
print(size)
print(realVidSize)
...
}
