Playing video with AVPlayer and recording sound with AVAudioRecorder simultaneously

问题 I was googling this problem for many days but I didn't find a solution for my simple problem. I'm trying to play a video while recording sound. Recording sound works fine without the video. And the video works fine without the recording. As soon as I put both together, the recording throws values which do not react on sound and the video is not playing anymore. By the way this happens only on my device (iPhone 4 / iOS5). In the simulator everything works fine. This is a reduced version of my

iPhone ios4 - Replacing iPod dock icon whilst playing background audio stream

由 给你一囗甜甜゛ 提交于 2019-12-29 14:56:55
问题 I've figured out how I can get audio playing in the background on ios4, however I've noticed that some apps also replace the iPod dock icon with their own app icon. (Last.fm & Spotify for example). They are also able to use the dock media controls to pause and resume their streams. Does anyone know how to do this? Thanks 回答1: It's easy you have to respond to the Remote Control Events. This also lets you control your app with the headset. In lets say viewDidLoad call: [[UIApplication

How to play multiple Audio Files simultaneously using AVPlayer?

问题 I am trying to play multiple audio files using 2 AVPlayer instances, but one of the player stops for a fraction of a second rather than playing all audio files simultaneously. The logic of the program is as follows: var player: AVPlayer? will stream an audio file from my database. On its own is playing perfectly. fileprivate var countPlayer: AVPlayer? plays the count number of the current item being played by var player . The count is a sequence of 1 to 8 and for each digit I am storing

AVPlayer之音乐播放

由 倖福魔咒の 提交于 2019-12-28 23:25:44
今天来整理一下以前自己学到的AVPlayer播放音乐的功能，这虽然简单，但是温故而知新嘛！下面说说做一个简单播放界面的思路和核心代码. 1.创建单例类MusicManager，模型类Music，音乐控制器MusicViewController， 和一个MusictableViewController 2.在单例中声明单例和获取数据，初始化模型数组 3.在表示图控制器中引入单例拿到数据：[[MusicManager shareInstance] getData];//这是单例中获取数据的方法 4.在表视图中显示数据 5.从表视图跳转到MusicViewController的方式：首先需要在故事版中将控制器和MusicViewController相关联，再设置storyboadID: 1)：在点击cell的方法中 通过表视图的故事版实例化MusicViewController 然后模态或者push过去 MusicViewController *musicVC = [self.storyboard instantiateViewControllerWithIdentifier:@"storyboadID"]； 2：通过从表视图的cell连线到MusicViewController上， 然后在表视图的下面方法中跳转：需要设置segue的标示符 - (void)prepareForSegue

Seek to a certain position in AVPlayer right after the asset was loaded

由 冷暖自知 提交于 2019-12-28 11:47:07
问题 This works: I have an AVPlayer which plays a video right after it was loaded. And this works fine. This doesn't : Instead of starting the video at the beginning, I want to play it at a given position. So I wait until the asset is ready for Play using KVO: BOOL isReadyToSeek = (self.playerItem.status == AVPlayerStatusReadyToPlay) And then seek to the given time [playerItem seekToTime:timeInTheMiddleOfTheVideo completionHandler:myHandler]; But the player will always start at the beginning of

问题 Using AVPlayer in a Mac app here to play random videos in fullscreen from a folder, but when I try to play .vob files or .mpg files I just get a black screen that lasts as long as the video lasts. Does AVFoundation not support playback from these containers? I figured that since they were playable with stock QuickTime Player they would also work with AVPlayer. 回答1: The AVURLAsset class has a static methods that you can query for supported video UTIs: + (NSArray *)audiovisualTypes On 10.9.1 it
