avplayer

问题 I'm using AVPlayer (I don't need to, but I wanna stream it and start playing as soon as possible) to play an m4a file (it's an iTunes audio preview). Only I only want it to play a part of that file. I'm able to set a start time but not an end time. Using a timer is not working because I'm using URL as a http address. I'm playing as it loads, without downloading the file. I also saw solutions in Objective-C to use KVO to know when music starts playing but I'm thinking this is not the best

问题 I am now trying to export an mp3 file that has been player using AVPlayer (using an url) so it doesn't have to be downloaded twice. This is my sample code: I've tried every outputFileType... self.exporter = [[AVAssetExportSession alloc] initWithAsset:self.asset presetName:AVAssetExportPresetPassthrough]; } NSError *error; NSLog(@"export.supportedFileTypes : %@",self.exporter.supportedFileTypes); // "com.apple.quicktime-movie", // "com.apple.m4a-audio", // "public.mpeg-4", // "com.apple.m4v

问题 I successfully enabled my app to be able to play audio and video in background after the screen is locked. However, for better user experience I want to show play and pause controls of the running media on the locked screen.

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 I've managed to reference images for my custom data model which is used to show unique cells their different information. I've been able to do it for images, as it's a lot easier, I just have no clue how to do it for videos. My data model looks like this: fileprivate let data = [ CustomData(title: "Test", image: #imageLiteral(resourceName: "ss-1"), url: "this-will-be-a-local-url-in-cache-to-a-video"), CustomData(title: "Test2", image: #imageLiteral(resourceName: "done-button"), url: "this

问题 I have somewhat of a confusing problem. I declared these variables in my class: var audioPlayer = AVPlayer() var videoPlayer = AVPlayer() var videoLayer = AVPlayerLayer() I have these codes for adding the container of the videoPlayer: let aspectHeight = view.frame.width * 9/16 let viewFrame = CGRect(x: 5, y: 0, width: view.frame.width - 10, height: aspectHeight) let layerFrame = CGRect(x: 0, y: 0, width: view.frame.width - 10, height: aspectHeight) videoPlayerContainerView.frame = viewFrame
