我有一些编辑视频的代码,然后创建一个AVAssetExportSession来保存编辑过的视频.我想将它保存到相机胶卷,但无法弄清楚NSURL是什么.
var session: AVAssetExportSession = AVAssetExportSession(asset: myasset,presetName: AVAssetExportPresetHighestQuality) session.outputURL = ??? session.exportAsynchronouslyWithCompletionHandler(nil)
有谁知道如何确定将视频保存到相机胶卷的正确NSURL？在此先感谢您的帮助.
解决方法
只需使用session.outputURL = ….就无法将视频直接保存到相机胶卷.您必须将视频保存到文件路径(临时或其他),然后将该视频的视频写入相机使用writeVideoAtPathToSavedPhotosAlbum :,滚动：
var exportPath: Nsstring = NstemporaryDirectory().stringByAppendingFormat("/video.mov")
var exportUrl: NSURL = NSURL.fileURLWithPath(exportPath)!
var exporter = AVAssetExportSession(asset: myasset,presetName: AVAssetExportPresetHighestQuality)
exporter.outputURL = exportUrl
exporter.exportAsynchronouslyWithCompletionHandler({
let library = ALAssetsLibrary()
library.writeVideoAtPathToSavedPhotosAlbum(exportURL,completionBlock: { (assetURL:NSURL!,error:NSError?) -> Void in
// ...
})
})
