Member Function Documentation
◆ endOfTrack()
|
virtual |
Return if the track has finished.
Implements Video::VideoDecoder::Track.
Reimplemented in Video::XboxMediaVideo::XMVVideoTrack.
Definition at line 528 of file decoder.cpp.
◆ getCurFrame()
|
pure virtual |
Get the current frame of this track.
Implemented in Video::QuickTimeDecoder::VideoTrackHandler, Video::XboxMediaVideo::XMVVideoTrack, and Video::Fader::FaderVideoTrack.
◆ getFrameCount()
|
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 in Video::QuickTimeDecoder::VideoTrackHandler, and Video::Fader::FaderVideoTrack.
◆ getFrameTime()
|
virtual |
Get the time the given frame should be shown.
By default, this returns a negative (invalid) value. This function should only be used by VideoDecoder::seekToFrame().
Reimplemented in Video::VideoDecoder::FixedRateVideoTrack.
Definition at line 532 of file decoder.cpp.
References Common::Timestamp::addFrames().
◆ getHeight()
|
pure virtual |
Get the height of this track.
Implemented in Video::QuickTimeDecoder::VideoTrackHandler, Video::XboxMediaVideo::XMVVideoTrack, and Video::Fader::FaderVideoTrack.
◆ getNextFrameStartTime()
|
pure virtual |
Get the start time of the next frame since the start of the video.
Implemented in Video::VideoDecoder::FixedRateVideoTrack, Video::QuickTimeDecoder::VideoTrackHandler, and Video::XboxMediaVideo::XMVVideoTrack.
◆ getTrackType()
|
inlinevirtual |
Get the type of track.
This must not return kTrackTypeNone.
Implements Video::VideoDecoder::Track.
Definition at line 231 of file decoder.h.
References Video::VideoDecoder::Track::kTrackTypeVideo.
◆ getWidth()
|
pure virtual |
Get the width of this track.
Implemented in Video::QuickTimeDecoder::VideoTrackHandler, Video::XboxMediaVideo::XMVVideoTrack, and Video::Fader::FaderVideoTrack.
