How to send video file to firebase storage in ios - ios

Question

I am working on a Video sharing iOS app and using Firebase5 as backend. It allow User can choose video and send it to storage. When I tried the video cannot push to database server. Below is my code:
static func uploadVideoToFirebaseStorage(videoUrl: URL, onSuccess: #escaping (_ videoUrl: String) -> Void) {
let videoIdString = NSUUID().uuidString
//Config.STORAGE_ROOT_REF is var STORAGE_ROOT_REF = "gs://****-cdc3c.appspot.com"
let storageRef = Storage.storage().reference(forURL: Config.STORAGE_ROOT_REF).child("posts").child(videoIdString)
storageRef.putFile(from: videoUrl, metadata: nil) { (metadata, error) in
if error != nil {
ProgressHUD.showError(error!.localizedDescription)
return
}
}
storageRef.downloadURL(completion: { (url, error) in
if let error = error {
return
}else {
let videoUrl = url!.absoluteString
onSuccess(videoUrl)
}
})
}

Call this function to upload the video to firebase storage
func uploadTOFireBaseVideo(url: URL,
success : #escaping (String) -> Void,
failure : #escaping (Error) -> Void) {
let name = "\(Int(Date().timeIntervalSince1970)).mp4"
let path = NSTemporaryDirectory() + name
let dispatchgroup = DispatchGroup()
dispatchgroup.enter()
let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
let outputurl = documentsURL.appendingPathComponent(name)
var ur = outputurl
self.convertVideo(toMPEG4FormatForVideo: url as URL, outputURL: outputurl) { (session) in
ur = session.outputURL!
dispatchgroup.leave()
}
dispatchgroup.wait()
let data = NSData(contentsOf: ur as URL)
do {
try data?.write(to: URL(fileURLWithPath: path), options: .atomic)
} catch {
print(error)
}
let storageRef = Storage.storage().reference().child("Videos").child(name)
if let uploadData = data as Data? {
storageRef.putData(uploadData, metadata: nil
, completion: { (metadata, error) in
if let error = error {
failure(error)
}else{
let strPic:String = (metadata?.downloadURL()?.absoluteString)!
success(strPic)
}
})
}
}
Following function converts the video to mp4 format so that it can be viewed on any device either it be iOS or android
func convertVideo(toMPEG4FormatForVideo inputURL: URL, outputURL: URL, handler: #escaping (AVAssetExportSession) -> Void) {
try! FileManager.default.removeItem(at: outputURL as URL)
let asset = AVURLAsset(url: inputURL as URL, options: nil)
let exportSession = AVAssetExportSession(asset: asset, presetName: AVAssetExportPresetHighestQuality)!
exportSession.outputURL = outputURL
exportSession.outputFileType = .mp4
exportSession.exportAsynchronously(completionHandler: {
handler(exportSession)
})
}

Call this function to upload video the firebase storage. Its working for me incase any confusion you can ask
static func upload(file: URL, completion: #escaping UploadCompletion) {
let name = "\(Int(Date().timeIntervalSince1970)).mp4"
do {
let data = try Data(contentsOf: file)
let storageRef =
Storage.storage().reference().child("Videos").child(name)
if let uploadData = data as Data? {
let metaData = StorageMetadata()
metaData.contentType = "video/mp4"
storageRef.putData(uploadData, metadata: metaData
, completion: { (metadata, error) in
if let error = error {
completion(nil, error.localizedDescription)
}else{
storageRef.downloadURL { (url, error) in
guard let downloadURL = url else {
completion(nil, error?.localizedDescription ?? "")
return
}
completion(downloadURL, nil)
}
}
})
}
}catch let error {
print(error.localizedDescription)
}
}
