'Use Apache tika get .mp4 file contentType,got "video/quicktime"

I use this function to get files contentType ，when use the .jpg file receive "image/jpg". use .mp4 receive "video/quicktime"

public static String detectMediaType(String fileName,byte[] data) {
    ByteArrayInputStream inputStream = new ByteArrayInputStream(data);
    AutoDetectParser parser = new AutoDetectParser();
    Detector detector = parser.getDetector();
    Metadata md = new Metadata();
    md.add(Metadata.RESOURCE_NAME_KEY, fileName);
    try{
        MediaType mediaType = detector.detect(inputStream, md);
        return mediaType.toString();
    }catch (IOException ex){
        throw new RuntimeException("Failed to detect mediaType for file: " + fileName,ex);
    }
}

Solution 1:[1]

This is expected because you are using tika detector functionality which for mp4 or for other QuickTime formats returns generic 'video/quicktime'. If you need to get exact type like 'video/mp4' you should additionally use tika parser, for example:

if (mediaType.equals(MediaType.video("quicktime"))) {
    Parser parser = new AutoDetectParser();
    ContentHandler handler = new BodyContentHandler();
    Metadata metadata = new Metadata();
    ParseContext context = new ParseContext();
    parser.parse(inputStream, handler, metadata, context);
}

I had the same problem using Tikas DefaultDetector.

The solution, as indicated here: https://tika.apache.org/2.3.0/detection.html (under "Container Aware Detection"), is to use TikeInputStream, instead of a standard InputStream.

detector.detect(TikaInputStream.get(inputStream), metadata);

Don't forget to close the streams
