VideoTrackHandler()

Video::QuickTimeDecoder::VideoTrackHandler::VideoTrackHandler	(	QuickTimeDecoder *	decoder,
		QuickTimeTrack *	parent
	)

Definition at line 965 of file quicktime.cpp.

Member Function Documentation

decodeNextFrame()

bool Video::QuickTimeDecoder::VideoTrackHandler::decodeNextFrame

(

Graphics::Surface &

surface

)

Definition at line 991 of file quicktime.cpp.

References Video::QuickTimeDecoder::VideoSampleDesc::_videoCodec.

getCurFrame()

int Video::QuickTimeDecoder::VideoTrackHandler::getCurFrame ( ) const

inlinevirtual

Get the current frame of this track.

Implements Video::VideoDecoder::VideoTrack.

Definition at line 238 of file quicktime.h.

References _curFrame.

getDuration()

Common::Timestamp Video::QuickTimeDecoder::VideoTrackHandler::getDuration ( ) const

virtual

Get the duration of the track.

By default, this returns 0 for unknown.

Reimplemented from Video::VideoDecoder::Track.

Definition at line 968 of file quicktime.cpp.

getFrameCount()

int Video::QuickTimeDecoder::VideoTrackHandler::getFrameCount ( ) const

virtual

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.

Definition at line 980 of file quicktime.cpp.

getFrameDuration()

uint32 Video::QuickTimeDecoder::VideoTrackHandler::getFrameDuration ( )

private

Definition at line 1055 of file quicktime.cpp.

getHeight()

uint32 Video::QuickTimeDecoder::VideoTrackHandler::getHeight ( ) const

virtual

Get the height of this track.

Implements Video::VideoDecoder::VideoTrack.

Definition at line 976 of file quicktime.cpp.

getNextFramePacket()

Common::SeekableReadStream * Video::QuickTimeDecoder::VideoTrackHandler::getNextFramePacket ( uint32 &  descId )

Here is the call graph for this function:

getNextFrameStartTime()

Common::Timestamp Video::QuickTimeDecoder::VideoTrackHandler::getNextFrameStartTime ( ) const

virtual

Get the start time of the next frame since the start of the video.

Implements Video::VideoDecoder::VideoTrack.

Definition at line 984 of file quicktime.cpp.

getWidth()

uint32 Video::QuickTimeDecoder::VideoTrackHandler::getWidth ( ) const

virtual

Get the width of this track.

Implements Video::VideoDecoder::VideoTrack.
