mp4

[rdcs]

I have used your tool very successfully, however, my code returns a null in the following when an mp4 is tested:
(The filePath extension is mp4)
NSUrl videoFileURL = NSUrl.FromString(filePath);
Uri uri = new Uri(videoFileURL.ToString());
StreamReader streamReader = new StreamReader(filePath);
FileInfo fileInfo = new FileInfo(filePath);

            Stream stream = streamReader.BaseStream;
            FileType fileType = MimeDetective.FileInfoExtensions.GetFileType(fileInfo);

(The fileType here is null)
This code works fine for .mov files (quicktime) but fails with mp4. Please let me know if I am using it incorrectly for these type of files or if there is actually an issue.
Thanks!

The library works by attempting to read file headers out of the actual file. MPEG files usually have a decent enough file header for the library to match against. However, it looks like you're on an apple device... Which can get weird as they're not consistent with their mp4 headers. Do you have a test file that repros this or the first 560 bytes of a file?
