回答1:

You can use the MediaMetadataRetriever class. It has getFrameAt() method wherein you can specify the time of the frame that you want to get.

For details refer to MediaMetadataRetriever

回答2:

Actually, MediaMetadataRetriever.getFrameAtTime uses microseconds as a parameter, not milliseconds. Once you make that change, you can get the correct frames from the video.
