I have problems about how to implement PlaybackParams to set video speed:
public PlaybackParams getPlaybackParams ()Added in API level 23
Gets the playback rate using PlaybackParams.
PlaybackParams setSpeed (float speed) //Sets the speed factor. Returns:
the playback rate being used.
Throws IllegalStateException:
if the internal sync engine or the audio track has not been initialized.
This is my code:
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { mp.setPlaybackParams(new PlaybackParams().setSpeed(1.f)); if (mPlaybackState == PlaybackState.PLAYING) { mVideoView.start();} } }); 3 Answers

You are getting an IllegalStateException while calling the 'setPlayParams' method, because you're not doing PlaybackParams params = mp.getPlaybackParams(), set the speed and then pass it to mp.setPlaybackParams()! Set the speed DIRECTLY while calling the mp.getPlayParams()!
MediaPlayer mp = ...; float speed = 0.55f; mp.setPlaybackParams(mp.getPlaybackParams().setSpeed(speed)); Let me now if it is useful!

After many try i find a solution.
Example how use VideoView
final VideoView mVideoView = findViewById(R.id.videoView); mVideoView.setVideoPath(Environment.getExternalStorageDirectory() + "/bluetooth/test.webm"); //Path of your file video mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer mp) { mp.setPlaybackParams(new PlaybackParams().setSpeed(0.55f)); mVideoView.start(); } }); MediaController media = new MediaController(this); //this is for play and restart play manually media.setAnchorView(mVideoView); mVideoView.setMediaController(media); //mVideoView.start();
