[jira] [Issue Comment Edited] (TIKA-851) M4V and M4A detection
invalid
[ https://issues.apache.org/jira/browse/TIKA-851?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13195027#comment-13195027 ]

Nick, although you add the ftyp for M4B (the bookmarkable format), you don't take into account its extension .m4b. Do you think you can add that?

> 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}
> Moreover, if the same test is run against an M4A file, the results are even more incorrect:
> {code}
> File + filename: video/quicktime
> File only: video/quicktime
> Filename only: application/octet-stream
> {code}
