Member Function Documentation

getWidth()

uint16 Grim::SmushDecoder::SmushVideoTrack::getWidth ( ) const

inlineoverridevirtual

Get the width of this track

Implements Video::VideoDecoder::VideoTrack.

getHeight()

uint16 Grim::SmushDecoder::SmushVideoTrack::getHeight ( ) const

inlineoverridevirtual

Get the height of this track

Implements Video::VideoDecoder::VideoTrack.

getPixelFormat()

Graphics::PixelFormat Grim::SmushDecoder::SmushVideoTrack::getPixelFormat ( ) const

inlineoverridevirtual

Get the pixel format of this track

Implements Video::VideoDecoder::VideoTrack.

getCurFrame()

int Grim::SmushDecoder::SmushVideoTrack::getCurFrame ( ) const

inlineoverridevirtual

Get the current frame of this track

See also

VideoDecoder::getCurFrame()

Implements Video::VideoDecoder::VideoTrack.

getFrameCount()

int Grim::SmushDecoder::SmushVideoTrack::getFrameCount ( ) const

inlineoverridevirtual

Get the frame count of this track

Note

If the frame count is unknown, return 0 (which is also the default implementation of the function). However, one must also implement endOfTrack() in that case.

Reimplemented from Video::VideoDecoder::VideoTrack.

getFrameRate()

Common::Rational Grim::SmushDecoder::SmushVideoTrack::getFrameRate ( ) const

inlineoverridevirtual

Get the rate at which this track is played.

Implements Video::VideoDecoder::FixedRateVideoTrack.

isSeekable()

bool Grim::SmushDecoder::SmushVideoTrack::isSeekable ( ) const

inlineoverridevirtual

Return if the track is seekable.

Reimplemented from Video::VideoDecoder::Track.

seek()

bool Grim::SmushDecoder::SmushVideoTrack::seek ( const Audio::Timestamp &  time )

inlineoverridevirtual

Seek to the given time.

Parameters

time	The time to seek to, from the beginning of the video.

Returns

true on success, false otherwise.

Reimplemented from Video::VideoDecoder::Track.

decodeNextFrame()

Graphics::Surface * Grim::SmushDecoder::SmushVideoTrack::decodeNextFrame ( )

overridevirtual

Decode the next frame

Implements Video::VideoDecoder::VideoTrack.

getPalette()

const byte * Grim::SmushDecoder::SmushVideoTrack::getPalette ( ) const

inlineoverridevirtual

Get the palette currently in use by this track

Reimplemented from Video::VideoDecoder::VideoTrack.

hasDirtyPalette()

bool Grim::SmushDecoder::SmushVideoTrack::hasDirtyPalette ( ) const

inlineoverridevirtual

Does the palette currently in use by this track need to be updated?

Reimplemented from Video::VideoDecoder::VideoTrack.
