      Description

      When the mime type of an M4V file is detected using its name only, it returns video/x-m4v. When it is detected using the InputStream (hence utilising the MagicDetector), it incorrectly returns video/quicktime.

      Using the sample M4V file from Apple's knowledge base:

      TikaTest.java
      public class TikaTest {
      
      	public static void main(String[] args) throws Exception {
      		String userHome = System.getProperty("user.home");
      
      		File file = new File(userHome + "/Desktop/sample_iPod.m4v");
      
      		InputStream is = TikaInputStream.get(file);
      
      		Detector detector = new DefaultDetector(
      			MimeTypes.getDefaultMimeTypes());
      
      		Metadata metadata = new Metadata();
      
      		metadata.set(Metadata.RESOURCE_NAME_KEY, file.getName());
      
      		System.out.println("File + filename: " + detector.detect(is, metadata));
      
      		System.out.println("File only:       " + detector.detect(is, new Metadata()));
      
      		System.out.println("Filename only:   " + detector.detect(null, metadata));
      	}
      
      }
      

      Renders the output:

      File + filename: video/quicktime
      File only:       video/quicktime
      Filename only:   video/x-m4v
      

      Moreover, if the same test is run against an M4A file, the results are even more incorrect:

      File + filename: video/quicktime
      File only:       video/quicktime
      Filename only:   application/octet-stream
