How to get duration of a video file?

Question

I\'m a beginner in Android programming.

I\'m writing an application to list all video file in a folder and display information of all videos in the folder. But when

Answer 1

Kotlin Extension Solution

Here is the way to fetch media file duration in Kotlin

fun File.getMediaDuration(context: Context): Long {
    if (!exists()) return 0
    val retriever = MediaMetadataRetriever()
    retriever.setDataSource(context, Uri.parse(absolutePath))
    val duration = retriever.extractMetadata(METADATA_KEY_DURATION)
    retriever.release()

    return duration.toLongOrNull() ?: 0
}

If you want to make it safer (Uri.parse could throw exception), use this combination. The others are generally just useful as well :)

fun String?.asUri(): Uri? {
    try {
        return Uri.parse(this)
    } catch (e: Exception) {
    }
    return null
}

val File.uri get() = this.absolutePath.asUri()

fun File.getMediaDuration(context: Context): Long {
    if (!exists()) return 0
    val retriever = MediaMetadataRetriever()
    retriever.setDataSource(context, uri)
    val duration = retriever.extractMetadata(METADATA_KEY_DURATION)
    retriever.release()

    return duration.toLongOrNull() ?: 0
}

Not necessary here, but generally helpful additional Uri extensions

val Uri?.exists get() = if (this == null) false else asFile().exists()

fun Uri.asFile(): File = File(toString())

public static long getDurationOfSound(Context context, Object soundFile)
  {
    int millis = 0;
    MediaPlayer mp = new MediaPlayer();
    try
    {
      Class<? extends Object> currentArgClass = soundFile.getClass();
      if(currentArgClass == Integer.class)
      {
        AssetFileDescriptor afd = context.getResources().openRawResourceFd((Integer)soundFile);
            mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
        afd.close();
      }
      else if(currentArgClass == String.class)
      {
        mp.setDataSource((String)soundFile);
      }
      else if(currentArgClass == File.class)
      {
        mp.setDataSource(((File)soundFile).getAbsolutePath());
      }
      mp.prepare();
      millis = mp.getDuration();
    }
    catch(Exception e)
    {
    //  Logger.e(e.toString());
    }
    finally
    {
      mp.release();
      mp = null;
    }
    return millis;
  }

Answer 3

MediaPlayer mpl = MediaPlayer.create(this,R.raw.videoFile);   
int si = mpl.getDuration();

This will give the duration of the video file

Answer 4

Use MediaMetadataRetriever to retrieve media specific data:

MediaMetadataRetriever retriever = new MediaMetadataRetriever();
//use one of overloaded setDataSource() functions to set your data source
retriever.setDataSource(context, Uri.fromFile(videoFile));
String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
long timeInMillisec = Long.parseLong(time );

retriever.release()

Answer 5

I think the easiest way is:

MediaPlayer mp = MediaPlayer.create(this, Uri.parse(uriOfFile));
int duration = mp.getDuration();
mp.release();
/*convert millis to appropriate time*/
return String.format("%d min, %d sec", 
        TimeUnit.MILLISECONDS.toMinutes(duration),
        TimeUnit.MILLISECONDS.toSeconds(duration) - 
        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration))
    );

Answer 6

MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource(uriOfFile);
long duration = Long.parseLong(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION))
int width = Integer.valueOf(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH));
int height = Integer.valueOf(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT));
retriever.release();
