Android从视频/拍摄视频时获取特定帧

[英]Android get specific frames from video/while filming video

My app is filming a video from which i need to get specific frames. 我的应用正在拍摄视频,我需要从中获取特定的帧。 Is it possible to save specific frames while taking the video or even after saving the video? 可以在拍摄视频时或保存视频后保存特定的帧吗? how? 怎么样?

EDIT: Another option is to take several pictures in a row with no video(moving the camera and taking a picture every second) is this possible? 编辑:另一个选择是连续拍摄几张图片而没有视频(移动相机并每秒拍摄一张图片),这可能吗?

The MediaMetadataRetriever class has a function called getFrameAtTime() . MediaMetadataRetriever类具有一个名为getFrameAtTime()的函数。 I think this works only after saving the file. 我认为这仅在保存文件后有效。 You will only get key frames. 您只会得到关键帧。
