Detect Corrupted Video

Question

Hi,

is there anyways to detect the event of video not playing because the video is not in the folder or because it is corrupted ?

When a video is not playing, there is a question pop up with a ok button to dismiss it.

Thank you in advance !!

Hello,​

Welcome to our Microsoft Q&A platform!

If you use this plugin: Plugin.MediaManager.Forms to play the video, when you play the corrupted or nonexistent Video, MediaItemFailed will be executed. You will get exception or message like following code.

   CrossMediaManager.Current.MediaItemFailed += Current_MediaItemFailed;  
       
     
           private void Current_MediaItemFailed(object sender, MediaManager.Media.MediaItemFailedEventArgs e)  
           {  
                
               Console.WriteLine(e.Message);  
               Console.WriteLine(e.Exeption);  
               
           }  

If you want to detect corrupted video from the video layer, you need to get the video's MD5 value, then read the video file compare the MD5 value. For example, I read AboutAssets.txt from the Assets folder. then compare it.

   public void Compare()  
           {  
                
               string content;  
               AssetManager asset1 = Android.App.Application.Context.Assets;  
               using (StreamReader sr = new StreamReader(asset1.Open("AboutAssets.txt")))  
               {  
                   content = sr.ReadToEnd();  
               }  
     
               var InPuthash= GetMd5Hash(content);  
               string hash = "sfsgDGDgds";  
               var result = VerifyMd5Hash(InPuthash, hash);  
              
     
           }  
           static string GetMd5Hash(string input)  
           {  
               using (MD5 md5Hash = MD5.Create())  
               {  
     
                   // Convert the input string to a byte array and compute the hash.  
                   byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));  
     
                   // Create a new Stringbuilder to collect the bytes  
                   // and create a string.  
                   StringBuilder sBuilder = new StringBuilder();  
     
                   // Loop through each byte of the hashed data   
                   // and format each one as a hexadecimal string.  
                   for (int i = 0; i < data.Length; i++)  
                   {  
                       sBuilder.Append(data[i].ToString("x2"));  
                   }  
     
                   // Return the hexadecimal string.  
                   return sBuilder.ToString();  
               }  
           }  
     
           // Verify a hash against a string.  
           static bool VerifyMd5Hash(string input, string hash)  
           {  
               // Hash the input.  
               string hashOfInput = GetMd5Hash(input);  
     
               // Create a StringComparer an compare the hashes.  
               StringComparer comparer = StringComparer.OrdinalIgnoreCase;  
     
               return 0 == comparer.Compare(hashOfInput, hash);  
     
           }
