how to get frame rate of video in android os? : <p>I want to get frame rate of video, but i don't want to use FFMPEG,JAVACV lib.
is that possible to get frame rate of video in android?</p>

<p>I read <a href="https://developer.android.com/reference/android/media/MediaFormat.html#KEY_FRAME_RATE" rel="noreferrer">KEY_FRAME_RATE</a> it's says that,"Specifically, MediaExtractor provides an integer value corresponding to the frame rate information of the track if specified and non-zero."
but i don't know how to use it?</p>
