java.io.FileNotFoundException: content://media/external/video/media/

The content://media/external/video/media/ is URI type and you need to query MediaStore to get full path name to the file.

Something like below:

public static String getFilePathFromContentUri(Uri selectedVideoUri,

        ContentResolver contentResolver) {

    String filePath;

    String[] filePathColumn = {MediaColumns.DATA};

    Cursor cursor = contentResolver.query(selectedVideoUri, filePathColumn, null, null, null);

    cursor.moveToFirst();

    int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

    try {

    filePath = cursor.getString(columnIndex);

    } catch (Exception e) {

// TODO Auto-generated catch block

//e.printStackTrace();

                //Need this in case the file not exist

    return null;

}

    cursor.close();

    return filePath;

}
