'Control the playback speed of video in android

I am using a VideoView to play a video file kept in res/raw. I couldnt find a way to control the playback speed of the video. Basically i want to reduce and increase the playback while moving a scroll bar. Is there any work around for implementing this?

No, you cannot change the playback rate by simply using VideoView. VideoView and MediaPlayer only provide limited media functions.

You have to use some third party library, e.g., PVPlayer, and implement that yourself.

That's also why good media players on Android are so valuable:)

you can use this but it works on api 23 and above

 mVideo.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {

            //works only from api 23
            PlaybackParams myPlayBackParams = null;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
                myPlayBackParams = new PlaybackParams();
                myPlayBackParams.setSpeed(0.8f); //you can set speed here
                mp.setPlaybackParams(myPlayBackParams);
            }

        }
    });

I want to say than Mk Kamal's solution have an unexpected side effect: calling setPlaybackParams in OnPreparedListener will force VideoView to repeat the latest played video when the app was returned from the background. I don't know is it a bug or a feature, but I found a way to avoid such behavior:

private float speed = 0.8f;
private final MediaPlayer.OnInfoListener listener = (mp, what, extra) -> {

    if (what == MediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START) {
        mp.setPlaybackParams(mp.getPlaybackParams().setSpeed(speed));
        return true;
    }
    return false;
};


videoView.setOnPreparedListener(
                mp -> {
                    mp.setOnInfoListener(listener);
                }
        );

MEDIA_INFO_VIDEO_RENDERING_START will be send only if the palyer was already started.

And I want to emphasize that getPlaybackParams is annotated as @NonNull, so it's not necessary to create new PlaybackParams object.

Kotlin variant, API above 23

val playerView = itemView.findViewById<VideoView>(R.id.videoview)
playerView.setVideoURI(Uri.parse("android.resource://" + context.packageName + "/" + R.raw.123.mp4))

playerView.setOnPreparedListener { mediaPlayer ->
   playerView.seekTo(1) // for video preview
   mediaPlayer.playbackParams = mediaPlayer.playbackParams.apply {
      speed = 0.6f
   }
   playerView.start()
}
