Compute OpenSubtitles Hash From Torrent File

Is it possible? If so how can I do that?

Its possible. You would use the streaming output.
From the stream, you can use the following logic to compute Opensub hash.
`
//From Sample code.
var manager = await Engine.AddStreamingAsync (link, "downloads");
var stream = await manager.StreamProvider.CreateStreamAsync (largestFile, false);

private string ComputeMovieHash(Stream input, long length = -1)
{

long lhash, streamsize;
streamsize = input.Length;
lhash = length == -1 ? streamsize : length;

long i = 0;
var buffer = new byte[sizeof(long)];
while (i < 65536 / sizeof(long) && (input.Read(buffer, 0, sizeof(long)) > 0))
{
    i++;
    lhash += BitConverter.ToInt64(buffer, 0);
}

input.Position = Math.Max(0, streamsize - 65536);
i = 0;
while (i < 65536 / sizeof(long) && (input.Read(buffer, 0, sizeof(long)) > 0))
{
    i++;
    lhash += BitConverter.ToInt64(buffer, 0);
}

var result = BitConverter.GetBytes(lhash);
Array.Reverse(result);
var stringBuilder = new StringBuilder();
for (var counter = 0; counter < result.Length; counter++)
{
    _=stringBuilder.Append(result[counter].ToString("x2"));
}

return stringBuilder.ToString();

}`
N.B the code was made by me but comes with 0 testing and maybe outdated. My player uses both filename, year and hash so I can't say now which works. :)

Not working application freezes

Would you please provide a sample application/repo to see what’s not working.
