The video plays perfectly as I want it to, but only once I watch a video that is clicked on in the UIImagePickerController elsewhere in the app. So for example, the AVPlayer will show a black background (this occurs with all of the AVPlayer's in the app), except for when I watch a video from the

Why AVPlayer ask several union range in same session?

问题 I'm would to know why AVPlayer ask's union ranges in requests. Example: 1. We have good wi-fi connection. 2. Track with total length = 1000000. AVPlayer in first will ask bytes=0-1 - its ok, it just "ping" the availability of track. But after that it will ask bytes=0-999999 - and get content-len 1000000 ; And after that it will ask bytes=40000-999999 - and get content-len 599999 ; Why it make third request if we must have all data from second request (bytes=0-999999)? 来源： https:/

用户点击了播放视频,但是此时手机是静音状态,产品说静音状态下也需要把声音给播放出来,so~ 原文: https://www.jianshu.com/p/998709165dfd 首先你要确保player的属性muted为NO，即非静音，当然NO是系统默认的。然后设置一下category即可 //静音状态下播放 [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil]; AVAudioSessionCategory是一个字符串枚举，讲一下几个常用的category的含义: // app的声音可与其它app共存，但锁屏和静音模式会被静音，除非当前app是唯一播放的app AVAudioSessionCategoryAmbient // 会停止其他程序的音频播放。当设备被设置为静音模式，音频会随之静音 AVAudioSessionCategorySoloAmbient // 仅用来录音，无法播放音频 AVAudioSessionCategoryRecord // 会停止其它音频播放，并且能在后台播放，锁屏和静音模式都能播放声音 AVAudioSessionCategoryPlayback // 能播也能录，播放默认声音是从听筒出来

问题 I'm having trouble with UISlider and AVPlayer scrubbing method. Every time the method is invoked the player restarts from 0. I tried debugging and seems that the slider value is right but when I Step Over, it's set 0, thus the player restarts. This is what I've tried: var desiredTime = CMTimeMake(Int64(self.progressSlider.value), 1) AudioManager.sharedInstance.audioPlayer.seekToTime(desiredTime) I've also tried looking at similar questions and found that it was the same when I tried their
