在MediaStore.Video.Media.DURATION期限错 [英] Wrong DURATION in MediaStore.Video.Media.DURATION
本文介绍了在MediaStore.Video.Media.DURATION期限错的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想在我的应用程序来记录的视频，我已经注意到，展示他们的持续时间后，我看错分钟\\秒。出现这种情况只与视频录制槽下面code。随着视频通过其他应用程序记录，持续时间显示正确的：
公共无效recordStream（）{ // MediaRecorder开始前释放相机
releaseCamera（）; 如果（！prepareMediaRecorder（））{
Toast.makeText（MainActivity.this，
在失败prepareMediaRecorder（）\\ n - 端 -
Toast.LENGTH_LONG）.show（）; } mediaRecorder.start（）;
}
} 私人布尔prepareMediaRecorder（）{ myCamera = getCameraInstance（）;
mediaRecorder =新MediaRecorder（）;
myCamera.stop preVIEW（）;
myCamera.unlock（）;
mediaRecorder.setCamera（myCamera）; mediaRecorder.setVideoSource（MediaRecorder.VideoSource.CAMERA）; CamcorderProfile轮廓= CamcorderProfile.get（CamcorderProfile.QUALITY_HIGH）; mediaRecorder.setAudioSource（MediaRecorder.AudioSource.CAMCORDER）;
mediaRecorder.setOutputFormat（MediaRecorder.OutputFormat.MPEG_4）;
mediaRecorder.setVideoFrameRate（profile.videoFrameRate）;
mediaRecorder.setVideoSize（profile.videoFrameWidth，profile.videoFrameHeight）;
mediaRecorder.setVideoEncodingBitRate（profile.videoBitRate）;
mediaRecorder.setAudioEncodingBitRate（profile.audioBitRate）;
mediaRecorder.setAudioChannels（profile.audioChannels）;
mediaRecorder.setAudioSamplingRate（profile.audioSampleRate）;
mediaRecorder.setVideoEn codeR（profile.video codeC）;
mediaRecorder.setAudioEn codeR（profile.audio codeC）;
}
//字符串outputfilename;
日期日期=新的日期（）;
。outputfilename =/ SD卡/视频/+与Date.toString（）代替（，_）。替换（：，_）+MP4 mediaRecorder.setOutputFile（outputfilename）;
mediaRecorder.set previewDisplay（mSurfaceView.getHolder（）getSurface（））; 尝试{
mediaRecorder prepare（）。
}赶上（IllegalStateException异常五）{
releaseMediaRecorder（）;
返回false;
}赶上（IOException异常五）{
releaseMediaRecorder（）;
返回false;
} 返回true; }
这是我如何从视频持续时间：
video_column_index = videocursor
.getColumnIndexOrThrow（MediaStore.Video.Media.DURATION）;
videocursor.moveToPosition（位置）; 持续时间长= videocursor.getLong（video_column_index）; 字符串转换=的String.format（％02D：％02D
TimeUnit.MILLISECONDS.toMinutes（持续时间），
TimeUnit.MILLISECONDS.toSeconds（持续时间） -
TimeUnit.MINUTES.toSeconds（TimeUnit.MILLISECONDS.toMinutes（持续时间））
）; holder.txtDuration.setText（转换）;
解决方案
在这样解决的：
MediaPlayer的MP = MediaPlayer.create（这一点，Uri.parse（outputfilename））;
INT持续时间= mp.getDuration（）;
mp.release（）; ContentValues值=新ContentValues（）;
values.put（MediaStore.Video.Media.DATA，outputfilename）;
values.put（MediaStore.Video.Media.DATE_TAKEN，dateTaken）;
values.put（MediaStore.Video.Media.DURATION，持续时间）;
这是计算和视频持续时间添加到MediaStore性能的需求。
I'm trying to record video in my application and I've noticed that displaying their duration, I see wrong minutes \ seconds. This happens only with the video recorded trough the following code. With the video recorded through other apps, the duration is displayed right:
public void recordStream() {
//Release Camera before MediaRecorder start
releaseCamera();
if(!prepareMediaRecorder()){
Toast.makeText(MainActivity.this,
"Fail in prepareMediaRecorder()!\n - Ended -",
Toast.LENGTH_LONG).show();
}
mediaRecorder.start();
}
}
private boolean prepareMediaRecorder(){
myCamera = getCameraInstance();
mediaRecorder = new MediaRecorder();
myCamera.stopPreview();
myCamera.unlock();
mediaRecorder.setCamera(myCamera);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
CamcorderProfile profile = CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setVideoFrameRate(profile.videoFrameRate);
mediaRecorder.setVideoSize(profile.videoFrameWidth, profile.videoFrameHeight);
mediaRecorder.setVideoEncodingBitRate(profile.videoBitRate);
mediaRecorder.setAudioEncodingBitRate(profile.audioBitRate);
mediaRecorder.setAudioChannels(profile.audioChannels);
mediaRecorder.setAudioSamplingRate(profile.audioSampleRate);
mediaRecorder.setVideoEncoder(profile.videoCodec);
mediaRecorder.setAudioEncoder(profile.audioCodec);
}
//String outputfilename;
Date date=new Date();
outputfilename="/sdcard/video/"+date.toString().replace(" ", "_").replace(":", "_")+".mp4";
mediaRecorder.setOutputFile(outputfilename);
mediaRecorder.setPreviewDisplay(mSurfaceView.getHolder().getSurface());
try {
mediaRecorder.prepare();
} catch (IllegalStateException e) {
releaseMediaRecorder();
return false;
} catch (IOException e) {
releaseMediaRecorder();
return false;
}
return true;
}
This is how I get duration from the video:
video_column_index = videocursor
.getColumnIndexOrThrow(MediaStore.Video.Media.DURATION);
videocursor.moveToPosition(position);
long duration = videocursor.getLong(video_column_index);
String converted = String.format("%02d:%02d",
TimeUnit.MILLISECONDS.toMinutes(duration),
TimeUnit.MILLISECONDS.toSeconds(duration) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration))
);
holder.txtDuration.setText(converted);
解决方案
solved in this way:
MediaPlayer mp = MediaPlayer.create(this, Uri.parse(outputfilename));
int duration = mp.getDuration();
mp.release();
ContentValues values = new ContentValues();
values.put(MediaStore.Video.Media.DATA, outputfilename);
values.put(MediaStore.Video.Media.DATE_TAKEN, dateTaken);
values.put(MediaStore.Video.Media.DURATION, duration);
It was the need to calculate and add the video duration to the MediaStore properties.
