Member Function Documentation

getWidth()

uint16 Video::AVIDecoder::AVIVideoTrack::getWidth ( ) const

inlinevirtual

Get the width of this track

Implements Video::VideoDecoder::VideoTrack.

getHeight()

uint16 Video::AVIDecoder::AVIVideoTrack::getHeight ( ) const

inlinevirtual

Get the height of this track

Implements Video::VideoDecoder::VideoTrack.

getPixelFormat()

Graphics::PixelFormat Video::AVIDecoder::AVIVideoTrack::getPixelFormat ( ) const

virtual

Get the pixel format of this track

Implements Video::VideoDecoder::VideoTrack.

setOutputPixelFormat()

bool Video::AVIDecoder::AVIVideoTrack::setOutputPixelFormat ( const Graphics::PixelFormat &  format )

virtual

Set the default high color format for videos that convert from YUV.

Reimplemented from Video::VideoDecoder::VideoTrack.

getCurFrame()

int Video::AVIDecoder::AVIVideoTrack::getCurFrame ( ) const

inlinevirtual

Get the current frame of this track

See also

VideoDecoder::getCurFrame()

Implements Video::VideoDecoder::VideoTrack.

getFrameCount()

int Video::AVIDecoder::AVIVideoTrack::getFrameCount ( ) const

inlinevirtual

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.

decodeNextFrame()

const Graphics::Surface* Video::AVIDecoder::AVIVideoTrack::decodeNextFrame ( )

inlinevirtual

Decode the next frame

Implements Video::VideoDecoder::VideoTrack.

getPalette()

const byte* Video::AVIDecoder::AVIVideoTrack::getPalette ( ) const

virtual

Get the palette currently in use by this track

Reimplemented from Video::VideoDecoder::VideoTrack.

hasDirtyPalette()

bool Video::AVIDecoder::AVIVideoTrack::hasDirtyPalette ( ) const

virtual

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

Reimplemented from Video::VideoDecoder::VideoTrack.

canDither()

bool Video::AVIDecoder::AVIVideoTrack::canDither ( ) const

virtual

Can the video track dither?

Reimplemented from Video::VideoDecoder::VideoTrack.

setDither()

void Video::AVIDecoder::AVIVideoTrack::setDither ( const byte *  palette )

virtual

Activate dithering mode with a palette

Reimplemented from Video::VideoDecoder::VideoTrack.

isRewindable()

bool Video::AVIDecoder::AVIVideoTrack::isRewindable ( ) const

inlinevirtual

Return if the track is rewindable.

If a video is seekable, it does not need to implement this for it to also be rewindable.

Reimplemented from Video::VideoDecoder::Track.

rewind()

bool Video::AVIDecoder::AVIVideoTrack::rewind ( )

virtual

Rewind the video to the beginning.

If a video is seekable, it does not need to implement this for it to also be rewindable.

Returns

true on success, false otherwise.

Reimplemented from Video::VideoDecoder::Track.

setReverse()

virtual bool Video::AVIDecoder::AVIVideoTrack::setReverse ( bool  reverse )

virtual

Set the video track to play in reverse or forward.

By default, a VideoTrack must decode forward.

Parameters

reverse

true for reverse, false for forward

Returns

true for success, false for failure

Reimplemented from Video::VideoDecoder::VideoTrack.

isReversed()

virtual bool Video::AVIDecoder::AVIVideoTrack::isReversed ( ) const

inlinevirtual

Is the video track set to play in reverse?

Reimplemented from Video::VideoDecoder::VideoTrack.

endOfTrack()

virtual bool Video::AVIDecoder::AVIVideoTrack::endOfTrack ( ) const

virtual

Returns true if at the end of the video track

Reimplemented from Video::VideoDecoder::VideoTrack.

getFrameRate()

Common::Rational Video::AVIDecoder::AVIVideoTrack::getFrameRate ( ) const

inlinevirtual

Get track frame rate

Implements Video::VideoDecoder::FixedRateVideoTrack.

setFrameRate()

void Video::AVIDecoder::AVIVideoTrack::setFrameRate ( const Common::Rational &  r )

inline

Force sets a new frame rate
