Detailed Description

An abstract representation of a track in a movie. Since tracks here are designed to work independently, they should not reference any other track(s) in the video.

Member Enumeration Documentation

TrackType

enum Video::VideoDecoder::Track::TrackType

The types of tracks this class can be.

Member Function Documentation

getTrackType()

virtual TrackType Video::VideoDecoder::Track::getTrackType ( ) const

pure virtual

Get the type of track.

Implemented in Video::VideoDecoder::AudioTrack, and Video::VideoDecoder::VideoTrack.

endOfTrack()

virtual bool Video::VideoDecoder::Track::endOfTrack ( ) const

pure virtual

Return if the track has finished.

Implemented in Video::VideoDecoder::AudioTrack, Video::VideoDecoder::VideoTrack, Video::AVIDecoder::AVIVideoTrack, and Video::FlicDecoder::FlicVideoTrack.

isRewindable()

virtual bool Video::VideoDecoder::Track::isRewindable ( ) const

virtual

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 in Video::VideoDecoder::RewindableAudioTrack, Video::AVIDecoder::AVIVideoTrack, and Video::FlicDecoder::FlicVideoTrack.

rewind()

virtual bool Video::VideoDecoder::Track::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 in Video::VideoDecoder::RewindableAudioTrack, Video::AVIDecoder::AVIVideoTrack, and Video::FlicDecoder::FlicVideoTrack.

isSeekable()

virtual bool Video::VideoDecoder::Track::isSeekable ( ) const

inlinevirtual

Return if the track is seekable.

Reimplemented in Video::VideoDecoder::SeekableAudioTrack.

seek()

virtual bool Video::VideoDecoder::Track::seek ( const Audio::Timestamp &  time )

inlinevirtual

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 in Video::VideoDecoder::SeekableAudioTrack.

pause()

void Video::VideoDecoder::Track::pause

(

bool

shouldPause

)

Set the pause status of the track.

isPaused()

bool Video::VideoDecoder::Track::isPaused ( ) const

inline

Return if the track is paused.

getDuration()

virtual Audio::Timestamp Video::VideoDecoder::Track::getDuration ( ) const

virtual

Get the duration of the track (starting from this track's start time).

By default, this returns 0 for unknown.

Reimplemented in Video::VideoDecoder::SeekableAudioTrack, and Video::VideoDecoder::FixedRateVideoTrack.

pauseIntern()

virtual void Video::VideoDecoder::Track::pauseIntern ( bool  shouldPause )

inlineprotectedvirtual

Function called by pause() for subclasses to implement.

Reimplemented in Video::VideoDecoder::AudioTrack.
