我正在开发一个使用ViewPager的应用,每个页面都有一个视频。一切都适用于所有智能手机,但在使用Android 4.1.2的Samnsung GT-I8260中无效。
所以在这款智能手机中,当我编译它时会返回IOException:Prepare failed:status = 0x1并指向mMediaPlayer.prepare();
现在代码是下一个:
//First of all I initilize MediaPlayer and I handle the Callback method for SurfaceView
mMediaPlayer = new MediaPlayer();
mSurfaceView.getHolder().addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
mMediaPlayer.release();
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
holder.setSizeFromLayout();
playVideoDelay();
}
@Override
public void surfaceChanged(SurfaceHolder holder,
int format, int width, int height) {
}
});
//The app plays the first video with the next method
private void playVideoDelay() {
try {
Uri path = Uri.parse("android.resource://com.casabioclimatica/raw/"+mVideoId);
mMediaPlayer.reset();
mMediaPlayer.setDataSource( mActivity, path);
mMediaPlayer.setDisplay(mSurfaceView.getHolder());
mMediaPlayer.prepare();
if (Build.VERSION.SDK_INT >= 16)
mMediaPlayer
.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
// fis = new FileInputStream(new File(path.getPath()));
//mMediaPlayer.setDataSource(fis.getFD());
} catch (Exception e) {
e.printStackTrace();
}
}
//When ViewPager changes it pages I call this method:
public void playVideoDelay(int videoId) {
try {
Uri path = Uri.parse("android.resource://com.casabioclimatica/raw/"+videoId);
mMediaPlayer.reset();
mMediaPlayer.setDataSource( mActivity, path);
mMediaPlayer.setDisplay(mSurfaceView.getHolder());
mMediaPlayer.prepare();
if (Build.VERSION.SDK_INT >= 16)
mMediaPlayer
.setVideoScalingMode(MediaPlayer.VIDEO_SCALING_MODE_SCALE_TO_FIT_WITH_CROPPING);
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
希望有人有类似的东西,知道正确的解决方案! 谢谢!
答案 0 :(得分:0)
经过大量代码更改后,我发现此智能手机存在问题,这是因为最大分辨率。在这种情况下,它有800 x 480像素,我使用1080 x 800,它太多了,Dalvik机器解释了这种情况,就像这个文件不存在或不起作用。我已经改变了文件的高宽和大小,它就像魅力一样!
因此对于任何类似的情况:请注意支持的最大屏幕分辨率,并尝试使用此大小以避免在渲染视频时出现任何奇怪的错误。
希望它有所帮助!
