Class Encoder

java.lang.Object
  encoder.Encoder

public class Encoder
extends java.lang.Object

The Encoder class deals with the encoding process.

This class takes a group of video frames as input and does encoding of those frames by using a desired video compression technique and outputs the encoded / compressed set of video frames.

Encoder

public Encoder(java.lang.String folderName,
               java.lang.String fileName,
               int imageWidth,
               int imageHeight,

               int frameRate,
               int bitRate,
               java.lang.String mode)

Constructs a Encoder initializes LinkedList, Node, Counters and DataFile

Parameters:

folderName - path to folder contains frames

fileName - common part of file of frames

imageWidth - of the frame of type int

imageHeight - of the frame of type int

frameNo - starting frame number of type int

numberOfFrames - Total number of the frames

groupOfFrames - number of frames in a group to be processed at a time

frameRate - of the video to feed the frames Integer

bitRate - the target bit rate

mode - String representation of the input like Frames, Video and Cam

Method Detail

encode

public void encode()

The main Encoder encoding process is handled by encode method

encode calculates bitsToRead for Y, Cb and Cr components and writes the data to the header file, reads the raw data and converts them to YCbCr starts the encoding process.

checkStatus

public void checkStatus(java.lang.String type)

Checks status of flag generated by internal process or any flag generated by user to stop Encoder Process

Parameters:

type - String representation of the Process type like camProcess, self

main

public static void main(java.lang.String[] args)

Main program of the class

Parameters:

args -

print

public static void print(java.lang.Process p,
                         java.lang.String type)

Prints the input, output and error streams of the process build by ProcessBuilder

print will redirects the process input, output and error streams of the process

Parameters:

p - is Process

type - is type of stream to print as String
