------------------------------------

             Summary: Parsing for OGV file with invalid checksum
                 Key: TIKA-1112
                 URL: https://issues.apache.org/jira/browse/TIKA-1112
             Project: Tika
          Issue Type: Bug
          Components: metadata, parser
    Affects Versions: 1.3
            Reporter: Alexander Chow


When parsing any OGV file (e.g., [Typing_example.ogv|http://commons.wikimedia.org/wiki/File:Typing_example.ogv]), log will output something like the following:

{code}
Warning - invalid checksum on page 2 of stream 155f (5471)
Warning - invalid checksum on page 3 of stream 155f (5471)
Warning - invalid checksum on page 4 of stream 155f (5471)
Warning - invalid checksum on page 5 of stream 155f (5471)
Warning - invalid checksum on page 6 of stream 155f (5471)
Warning - invalid checksum on page 7 of stream 155f (5471)
...

My test code was the following:

{code:java}

	void parse(String fileName) throws Exception {
		InputStream inputStream = new FileInputStream(fileName);
		
		Metadata metadata = new Metadata();
		
		Parser parser = new AutoDetectParser();
		
		ParseContext parserContext = new ParseContext();

		parserContext.set(Parser.class, parser);

		ContentHandler contentHandler = new WriteOutContentHandler(
			new DummyWriter());

		parser.parse(inputStream, contentHandler, metadata, parserContext);
		
		System.out.println(metadata);
	}
{code}
