avplayeritem

问题 I am implementing AVPlayer (not AVAudioPlayer) and trying to play audio from URL. It is working fine. But as we know that sometimes we can have invalid URL (URL that does not have Audio byte). When I play audio from any URL AVPlayer status shows always AVPlayerStatusReadyToPlay which is wrong. For example : In URL part if give invalid URL like : http://soundx.mp3slash.net/indian/jhankar_beats/1%28mp3pk.com%29.mp3 (it does not works even in your browser) and even if you give https:/

问题 I'm trying to read the duration of a locally stored audio file using the following code: #import <Foundation/Foundation.h> #import <CoreMedia/CoreMedia.h> #import <AVFoundation/AVFoundation.h> AVPlayer *player = [AVPlayer playerWithURL: urlForLocalAudioFile]; // busy wait - I know, not elegant, please ignore int timeout = 0; while (([player status] == AVPlayerStatusUnknown || [[player currentItem] status] == AVPlayerItemStatusUnknown) && timeout < 100) { [NSThread sleepForTimeInterval: 0.1];

问题 I have a vc that has an AVPlayer inside of it. From that vc I can push on a different vc with another player inside of it and I can keep pushing on more vcs with a player inside them also. After about the 14th vc getting pushed on the app crashes with Terminated due to memory issue . When I look at the memory graph (9th icon in left pane) it's at about 70mb so there isn't an obscene jump in memory. All of my video files are saved to and retrieved from disk and whenever I pop a vc I have a

问题 In a WWDC 2016 video, Apple says create the AVPlayer without an AVPlayerItem, create the AVPlayerLayer, and then assign the AVPlayerItem to the AVPlayer. I got the above code from @matt's Programming iOS 10 book. In it he says: Apparently there is some sort of efficiency if you do things in this order. The reason, it turns out, is that when an AVPlayerItem is assigned to an AVPlayer that doesn't have and associated AVPlayerLayer, the AVPlayer assumes that only the audio track of the AVAssest

问题 I'm using AVPlayer which I connect to an remote URL via an AVPlayerItem . The problem is that I want to play the sound from the URL immediately and don't let the user wait for the AVPlayer to buffer. The thing is that if the remote URL's asset media is very short then it doesn't buffer for long at all but if the media is a bit longer it takes a while. Is there a way to skip the buffering process or at least shorten it substantially? 回答1: Swift 5 You just need to use the

问题 I am trying to create a table view such that I am able to play videos . I am able to do this using AVPlayer and layer. I want to add a custom play and pause button with a slider to the bottom of a video view. AVPlayerController comes built in with these controls. How can I implement these in AVPlayer. I have been looking for examples. But I haven't found any. Are there any GitHub examples or code samples that I can follow? Any help will be really appreciated. 回答1: here I add the points , you

问题 Sometimes AVPlayer fails with AVPlayerItemStatusFailed and after that failure occurred, AVPlayer continues to failed with AVPlayerItemStatusFailed . I tried to clear the AVPlayer instance and create new one, but I cannot achieve AVPlayerItemStatusFailed failure to solve. Also removingFromSuperview UIView with AVPlayer instance and initializing new item with AVPlayer does not solve the problem. So I figured that out AVPlayer couldn't been cleared completely. Is there anybody suggest anything
