Class FLVParser

java.lang.Object

org.apache.tika.parser.video.FLVParser

All Implemented Interfaces:

Serializable, Parser

public class FLVParser
extends Object
implements Parser

Parser for metadata contained in Flash Videos (.flv). Resources: http://osflash.org/flv and for AMF: http://download.macromedia.com/pub/labs/amf/amf0_spec_121207.pdf

This parser is capable of extracting the general metadata from header as well as embedded metadata.

Known keys for metadata (from file header):

1. hasVideo: true|false
2. hasSound: true|false

In addition to the above values also metadata that is inserted in to the actual stream will be picked. Usually there are keys like: hasKeyframes, lastkeyframetimestamp, audiocodecid, keyframes, filepositions, hasMetadata, audiosamplerate, videodatarate metadatadate, videocodecid, metadatacreator, audiosize, hasVideo, height, audiosamplesize, framerate, hasCuePoints width, cuePoints, lasttimestamp, canSeekToEnd, datasize, duration, videosize, filesize, audiodatarate, hasAudio, stereo audiodelay

parse

public void parse(InputStream stream,
 ContentHandler handler,
 Metadata metadata,
 ParseContext context)
           throws IOException,
SAXException,
TikaException

Description copied from interface: Parser

Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

Specified by:

parse in interface Parser

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

IOException - if the document stream could not be read

SAXException - if the SAX events could not be processed

TikaException - if the document could not be parsed
