encode video file at specific time of the video

Question

i have video file in the sdcard. i want to encode the video file at minute 3 to 5. what im trying to say is,

let say, the complete video file is 10 minute. now i need to retrieve the video data at 3 to 5 minutes of the video to be encode and do the next process.

i have done it before but only encoded the complete video file and i dont have any idea to encoded the video file at specific time of the video. please help with this. Below is my encoded complete video file code:

public void loadVideo(){        
    //convert whole file into byte
    File file = new File("/sdcard/videooutput.mp4");                
    byte[] fileData = new byte[(int) file.length()];

    FileInputStream in; 
    try {
        in = new FileInputStream(file);         
        try {
            in.read(fileData);
            for(int readNum; (readNum = in.read(fileData)) != -1;){                 
            }
        } catch (IOException e) {
            Toast.makeText(this, "IO exc READ file", 2500).show();
            e.printStackTrace();
        }
        try {
            in.close();
        } catch (IOException e) {
            Toast.makeText(this, "IO exc CLOSE file", 2500).show();
            e.printStackTrace();
        }

        String encoded = Base64.encodeToString(fileData, Base64.DEFAULT);
        hantar(encoded);
    } catch (FileNotFoundException e) {
        Toast.makeText(this, "FILE NOT FOUND", 2500).show();
        e.printStackTrace();
    }

Please guide me with this. Thanks for advance.

You can try to use this class. It crops video from start to end position and saves cropped video to the file in your file system. Or you can use it to implement your own solution.

OK so you need to cut or trim the video and after that encode it. I'll change the answer. – petrsyn Oct 25 '12 at 08:49
