M4V magic detection invalid --------------------------- Key: TIKA-851 URL: https://issues.apache.org/jira/browse/TIKA-851 Project: Tika Issue Type: Bug Components: mime Affects Versions: 1.0 Reporter: Alexander Chow
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|http://support.apple.com/kb/HT1425]: {code:title=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)); } } {code} Renders the output: {code} File + filename: video/quicktime File only: video/quicktime Filename only: video/x-m4v {code} -- This message is automatically generated by JIRA.
