Detailed Description
A VideoTrack that is played at a constant rate.
If the frame count is unknown, you must override endOfTrack().

Member Function Documentation
◆ getDuration()
|
virtual |
Get the duration of the track.
By default, this returns 0 for unknown.
Reimplemented from Video::VideoDecoder::Track.
Definition at line 561 of file decoder.cpp.
◆ getFrameAtTime()
| uint Video::VideoDecoder::FixedRateVideoTrack::getFrameAtTime | ( | const Common::Timestamp & | time | ) | const |
Get the frame that should be displaying at the given time.
This is helpful for someone implementing seek().
Definition at line 548 of file decoder.cpp.
References Common::Timestamp::framerate(), and Common::Timestamp::totalNumberOfFrames().
◆ getFrameRate()
|
protectedpure virtual |
Get the rate at which this track is played.
Implemented in 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 from Video::VideoDecoder::VideoTrack.
Definition at line 544 of file decoder.cpp.
◆ getNextFrameStartTime()
|
virtual |
Get the start time of the next frame since the start of the video.
Implements Video::VideoDecoder::VideoTrack.
Definition at line 537 of file decoder.cpp.
