Class OggDetector

java.lang.Object

org.apache.tika.detect.ogg.OggDetector

All Implemented Interfaces:

Serializable, SelfConfiguring, Detector

public class OggDetector
extends Object
implements Detector

Detector for identifying specific file types stored within an Ogg container. Xiph provide a fairly unhelpful guide to mimetypes at https://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions but we try to use more specific ones, as given by the Tika mimetypes xml file.

Description copied from interface: Detector

Detects the content type of the given input document. Returns application/octet-stream if the type of the document can not be detected.

If the document input stream is not available, then the first argument may be null. Otherwise the detector may read bytes from the start of the stream to help in type detection. The detector is expected to mark the stream before reading any bytes from it, and to reset the stream before returning. The stream must not be closed by the detector.

The given input metadata is only read, not modified, by the detector.

Specified by:

detect in interface Detector

Parameters:

tis - document input stream, or null

metadata - input metadata for the document

parseContext - the parse context

Returns:

detected media type, or application/octet-stream

Throws:

IOException - if the document input stream could not be read

toMediaType

protected static MediaType toMediaType(org.gagravarr.ogg.OggStreamIdentifier.OggStreamType type)

Converts from vorbis-java type to Tika's type
