parseFile()

bool Common::QuickTimeParser::parseFile

(

const Path &

filename

)

Load a QuickTime file

Parameters

filename

the filename to load

parseStream()

bool Common::QuickTimeParser::parseStream	(	SeekableReadStream *	stream,
		DisposeAfterUse::Flag	disposeFileHandle = DisposeAfterUse::YES
	)

Load a QuickTime file from a SeekableReadStream

Parameters

stream	the stream to load
disposeFileHandle	whether to delete the stream after use

close()

void Common::QuickTimeParser::close

(

)

Close a QuickTime file

flattenEditLists()

void Common::QuickTimeParser::flattenEditLists

)

Flattens edit lists to a single edit containing the first edit contiguously through the last edit. Used to work around bad edit offsets.

setChunkBeginOffset()

void Common::QuickTimeParser::setChunkBeginOffset ( uint32  offset )

inline

Set the beginning offset of the video so we can modify the offsets in the stco atom of videos inside the Mohawk/mTropolis archives

Parameters

offset

the beginning offset of the video

getTimeScale()

uint32 Common::QuickTimeParser::getTimeScale ( ) const

inline

Returns the movie time scale

isOpen()

bool Common::QuickTimeParser::isOpen ( ) const

inline

Find out if this parser has an open file handle
