Member Function Documentation

◆ loadFile()

bool Video::QuickTimeDecoder::loadFile ( const Common::Path & filename )

virtual

Load a video from a file with the given name.

A default implementation using Common::File and loadStream is provided.

Parameters

filename the filename to load

Returns: whether loading the file succeeded

Reimplemented from Video::VideoDecoder.

◆ loadStream()

bool Video::QuickTimeDecoder::loadStream ( Common::SeekableReadStream * stream )

virtual

Load a video from a generic read stream. The ownership of the stream object transfers to this VideoDecoder instance, which is hence also responsible for eventually deleting it.

Implementations of this function are required to call addTrack() for each track in the video upon success.

Parameters

stream the stream to load

Returns: whether loading the stream succeeded

Implements Video::VideoDecoder.

◆ close()

void Video::QuickTimeDecoder::close ( )

virtual

Close the active video stream and free any associated resources.

All subclasses that need to close their own resources should still call the base class' close() function at the start of their function.

Reimplemented from Video::VideoDecoder.

◆ getWidth()

uint16 Video::QuickTimeDecoder::getWidth ( ) const

inlinevirtual

Returns the width of the video's frames.

By default, this finds the largest width between all of the loaded tracks. However, a subclass may override this if it does any kind of post-processing on it.

Returns: the width of the video's frames

Reimplemented from Video::VideoDecoder.

◆ getHeight()

uint16 Video::QuickTimeDecoder::getHeight ( ) const

inlinevirtual

Returns the height of the video's frames.

By default, this finds the largest height between all of the loaded tracks. However, a subclass may override this if it does any kind of post-processing on it.

Returns: the height of the video's frames

Reimplemented from Video::VideoDecoder.

◆ decodeNextFrame()

const Graphics::Surface* Video::QuickTimeDecoder::decodeNextFrame ( )

virtual

Decode the next frame into a surface and return the latter.

A subclass may override this, but must still call this function. As an example, a subclass may do this to apply some global video scale to individual track's frame.

Note that this will call readNextPacket() internally first before calling the next video track's decodeNextFrame() function.

Returns: a surface containing the decoded frame, or 0

Note: Ownership of the returned surface stays with the VideoDecoder, hence the caller must not free it.; this may return 0, in which case the last frame should be kept on screen

Reimplemented from Video::VideoDecoder.

◆ getDuration()

Audio::Timestamp Video::QuickTimeDecoder::getDuration ( ) const

inlinevirtual

Get the duration of the video.

If the duration is unknown, this will return 0. If this is not overriden, it will take the length of the longest track.

Reimplemented from Video::VideoDecoder.
