Such Problem: I have video file recorded with two sound channels. I have
tried to switch off left sound channel by this code:
Code:
Videoview vv;
...............
vv.setOnPreparedListener(new OnPreparedListener() {
@Override public void onPrepared(MediaPlayer mp) {
mp.setVolume(0.f, 1f);
}
});
... and on Tablet this work good (right volume channel sounds well). But
then I tried it on googleTv and this code did not work, sound swichs off; mp
.setVolume(1.f,0.f) - has no effect, sound continues playing in both
channels.
*Then I tried this:*
Code:
public class MainActivity extends Activity {
MediaPlayer mp = null;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (mp != null) {
mp.reset();
mp.release();
}
mp = MediaPlayer.create(this, R.raw.test);
mp.start();
}
public void onTurnOffLeft(View v){
mp.setVolume(0.f, 1.f);
}
public void onTurnOffRight(View v){
mp.setVolume(1.f, 0.f);
}
}
Method onTurnOffLeft switchs off all sound, and onTurnOffRight method has
no effect.
I have tested on *Visio Co-Star*, and* Logitech Revue* google tv boxes with
Optical
and HDMI cables.
First I thougth the problem is in hdmi cable, but a have tried to connect
lenovo tablet to TV through hdmi cable, and experiment with swithing off
sound channels finished with success. So, I need help with this problem.
Any ideas would be helpfull. Thank you.
