If you want to detect corrupted video while picking video, you could compare the MD5 value.
But on this way, you need to have correct the MD5 value. For example, i put the correct MD5 value in .txt file of Assets folder and then get the MD5 value when picking video and 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);
}
