摘要： An example apparatus is caused to receive a video sequence of a plurality of frames, and activate one of a plurality of available decoding processes based on a comparison of a size of the frames to a predefined threshold. The apparatus is also caused to select some but not all of the frames of the video sequence as potential key frames of the video sequence. The selected frames are located at or close to predefined positions along a length of the video sequence. The apparatus is also caused to decode the potential key frames according to the activated decoding process, and cause output of at least some of the potential key frames as key frames of the video sequence. The apparatus may be caused to discard from the potential key frames, one or more plain frames and/or a frame identified as being similar to other potential key frames.
摘要翻译：使得示例性装置接收多个帧的视频序列，并且基于将帧的大小与预定阈值的比较来激活多个可用解码处理中的一个。该设备还被导致选择视频序列的一些但不是全部的帧作为视频序列的潜在关键帧。所选择的帧位于或靠近视频序列的长度的预定位置。该装置还根据激活的解码处理对潜在的关键帧进行解码，并且使至少一些潜在的关键帧的输出作为视频序列的关键帧。可以使该装置从潜在的关键帧，一个或多个明确的帧和/或被识别为类似于其他潜在的关键帧的帧丢弃。

摘要： An example apparatus is caused to receive a video sequence of a plurality of frames, and perform a number of operations as each of at least some of the frames is received but before all of the frames are received. The apparatus is caused to calculate a score for the frame, and compare the score for the frame to a predefined threshold. The apparatus is caused to cause output of the frame as a key frame in an instance in which the frame is received within a specified period of time and the score for the frame is above the predefined threshold. Otherwise, in an instance in which none of the scores for frames received within the specified period of time is above the predefined threshold, the apparatus is caused to cause output of one of the frames received within the specified period of time as a key frame.
摘要翻译：使得示例设备接收多个帧的视频序列，并且在接收到至少一些帧中的每一个之后但在接收到所有帧之前执行多个操作。使该装置计算该帧的分数，并将该帧的得分与预定义的阈值进行比较。导致该装置在帧的指定时间段内接收帧的情况下将帧的输出作为关键帧，并且帧的分数高于预定阈值。否则，在指定时间段内接收到的帧的分数都不高于预定义阈值的情况下，使装置将指定时间段内接收到的一个帧的输出作为关键帧。
