XuggleVideo介绍

[英]Wraps a Xuggle video reader into the OpenIMAJ Video interface.

Some Notes:

The #hasNextFrame() method must attempt to read the next packet in the stream to determine if there is a next frame. That means that it incurs a time penalty. It also means there's various logic in that method and the #getNextFrame() method to avoid reading frames that have already been read. It also means that, to avoid #getCurrentFrame() incorrectly returning a new frame after #hasNextFrame() has been called, the class may be holding two frames (the current frame and the next frame) after #hasNextFrame() has been called.

The constructors have signatures that allow the passing of a boolean that determines whether the video is looped or not. This has a different effect than looping using the VideoDisplay. When the video is set to loop it will loop indefinitely and the timestamp of frames will be consecutive. That is, when the video loops the timestamps will continue to increase. This is in contrast to setting the VideoDisplay end action (using VideoDisplay#setEndAction(org.openimaj.video.VideoDisplay.EndAction)where the looping will reset all timestamps when the video loops.
[中]将Xuggle视频阅读器包装到OpenIMAJ视频接口中。
注意：
#hasNextFrame（）方法必须尝试读取流中的下一个数据包，以确定是否存在下一个帧。这意味着它会受到时间惩罚。这还意味着该方法和#getNextFrame（）方法中有各种逻辑，可以避免读取已经读取的帧。这还意味着，为了避免在调用#hasNextFrame（）后#getCurrentFrame（）错误地返回新帧，该类可能在调用#hasNextFrame（）后保留两个帧（当前帧和下一帧）。
构造函数具有允许传递布尔值的签名，该布尔值决定视频是否循环。这与使用VideoDisplay循环的效果不同。当视频设置为循环时，它将无限循环，帧的时间戳将是连续的。也就是说，当视频循环时，时间戳将继续增加。这与设置VideoDisplay结束操作（使用VideoDisplay#setEndAction（org.openimaj.video.VideoDisplay.EndAction））形成对比，在该操作中，当视频循环时，循环将重置所有时间戳。
