i am trying to retrieve meta data from media file approx 1gb
File file = null;
FileInputStream fis = null;
byte fullData[] = null;
byte requiredData[] = null;
try{
file = new File(fileName);
fis = new FileInputStream(file);
long filelen=file.length();
System.out.print("File Length:"+filelen);
fullData = new byte[ (int) filelen];
fis.read(fullData,0,(int)file.length()-11);
int len = (int)file.length()-11;
System.out.print("File Length:"+len);
