I am trying to use ExoPlayer
, as opposed to MediaPlayer
and I can't seem to figure it out...
MediaPlayer
has .start()
/ .pause()
commands... and I can just seekTo(1287)
and it automatically starts playing...
How do I do this with ExoPlayer
? I have tried to do seekTo(1287)
but it doesn't start playing after... I have also added .setPlayWhenReady(true)
after that, and still no luck...
I am able to .stop()
... but I can't get it to start playing again after that unless I .prepare()
again... but I don't think I should have to do that between every pause and play.
I am using my own controls and methods opposed to MediaController
like in the ExoPlayer Demo... I can't quite see how the controls are implemented...
Any suggestions anyone?
Edit:
OK, I figured out pause and start...
.setPlayWhenReady(true) // start
.setPlayWhenReady(false) // pause
But I'm still having problems with the tracking... .seekTo
works intermittently... sometimes it works... but other times I get this error:
E/AudioTrack: AudioTrack::set : Exit
(and it only gets to the buffer state... doesn't quite get to "ready"...
The official example of the PlayerControl
in the ExoPlayer source code do exactly what you asked:
public class PlayerControl implements MediaPlayerControl { private final ExoPlayer exoPlayer; public PlayerControl(ExoPlayer exoPlayer) { this.exoPlayer = exoPlayer; } @Override public boolean canPause() { return true; } @Override public boolean canSeekBackward() { return true; } @Override public boolean canSeekForward() { return true; } @Override public int getAudioSessionId() { throw new UnsupportedOperationException(); } @Override public int getBufferPercentage() { return exoPlayer.getBufferedPercentage(); } @Override public int getCurrentPosition() { return exoPlayer.getDuration() == ExoPlayer.UNKNOWN_TIME ? 0 : (int) exoPlayer.getCurrentPosition(); } @Override public int getDuration() { return exoPlayer.getDuration() == ExoPlayer.UNKNOWN_TIME ? 0 : (int) exoPlayer.getDuration(); } @Override public boolean isPlaying() { return exoPlayer.getPlayWhenReady(); } @Override public void start() { exoPlayer.setPlayWhenReady(true); } @Override public void pause() { exoPlayer.setPlayWhenReady(false); } @Override public void seekTo(int timeMillis) { long seekPosition = exoPlayer.getDuration() == ExoPlayer.UNKNOWN_TIME ? 0 : Math.min(Math.max(0, timeMillis), getDuration()); exoPlayer.seekTo(seekPosition); } }
If you are experiencing strange behaviors during the seek operation, it may be due to you particular stream/file type. I can suggest you to take a look at the base implementation of the ExoPlayer and, eventually, report any issue on Github.
