视频一帧一帧求 [英] Video Frame by Frame seeking

问题描述

有没有办法来逐步通过画面的视频文件的框架？我使用的是VideoView尝试和我有轻微的成功。我能得到通过视频关键帧而不是单个帧的步骤。我想这将是默认的设置，尤其是与路视频融为一体pression作品。有没有一种方法来覆盖此默认行为或配置，我可以改变吗？

Is there a way to step through a video file frame by frame? I've tried using a VideoView and I've had minor success. I can get the video the step through key frames but not individual frames. I figured this would be the default settings, especially with the way video compression works. Is there a way to override this default behavior or a configuration I can change?

推荐答案

在stagefright媒体框架的默认行为是始终寻求关键帧。 （相对于前面的框架的 - 的OpenCore其默认搜索行为是寻求到时间）

The default behaviour in stagefright media framework is always to seek to key frame. (As opposed to the earlier framework's - opencore whose default seeking behaviour was to seek to time.)

您不能使用MediaPlayer的API的搭载Android提供做一帧一帧搜索。

You cannot do frame by frame seeking by using the MediaPlayer API's provided by Android.

如果你真的想实​​现逐帧求，那么你将不得不使用第三方的多媒体框架，比如FFmpeg中或者需要实现自己的。

If you really want implement frame by frame seeking then you will have to use a 3rd party multimedia framework like FFMPEG or you will need to implement your own.
