ABSTRACT

ON-CLICK VIDEO is the live video broadcasting system for a college to broadcast

different events of the college. This system support different types of users such as admin,

staff, parents, students and others.

Streaming media is multimedia that is constantly received by and presented to an end-

user while being delivered by a streaming provider. The name refers to the delivery method

of the medium rather than to the medium itself. The distinction is usually applied to media

that are distributed over telecommunications networks, as most other delivery systems are

either inherently streaming (e.g., radio, television) or inherently non-streaming

(e.g., books, video cassettes, audio CDs). The verb 'to stream' is also derived from this term,

meaning to deliver media in this manner. Internet television is a commonly streamed

medium.

Live streaming, more specifically, means taking the video and broadcasting it live over the

Internet. The process involves a camera for the video, an encoder to digitize the content, a

video publisher where the streams are made available to potential end-users and a content

delivery network to distribute and deliver the content. The media can then be viewed by

end-users live.

The vlcj project is an Open Source project that provides Java bindings for the excellent vlc

media player from VideoLAN.

The bindings can be used to build media player client and server software using Java -

everything from simply playing local media files to a full-blown video-on-demand

streaming server is possible. With vlcj you can send or receive a live media broadcast, such

as live radio and television broadcasts, or real time teleconferences over the Internet or an

intranet.

Mini Project Report 2011 ON-CLICK VIDEO

1. INTRODUCTION

1.1 ABOUT ON-CLICK VIDEO

In this project, we designed and constructed a live media streaming system to broadcast

important activities such as: graduation ceremonies, sport games, banquets, and seminar

presentation etc.

Since 1990s up to now, the network has become more popular in the world. The Internet

supports popular services such as World Wide Web (www), e-mail, file transfer and file

sharing, web search, VoIP, BBS, Telnet, gaming, commerce, streaming technology,

publishing, video on demand, and etc.

Functions of Internet also offers file sharing and transferring. It is generally believed that

bandwidth is limited, and network resources are increasing more and more. If clients

download huge media files directly, would make this problem even worse. In order to

resolve the problem of bandwidth limitation, many network technologies have been

developed in recent years, such as streaming technology.

Nowadays, streaming media has already become very popular. There are many streaming

media services, for instance YouTube and Yahoo video. The characteristics of streaming

systems can reduce the server loading, and rapidly synchrony presented the media. The

technology of streaming allows users or clients to view or hear media objects without

having to wait until the entire media is downloaded, instead of downloading media files

directly and entirely. Based on above characteristics, streaming technology would reduce

the bandwidth requirement and provide solution of this problem.

On click video is a web application which provide live video streaming of different events

in the college. Besides live video streaming it also support recorded video streaming. This

application support different types of users such as registered users and unregistered users.

STATEMENT ABOUT THE PROBLEM

There are many systems which provide video streaming. But we can not expect

much about the privacy of that video. But we know that the videos of the college should be secured. Here, by providing different user classes and assigning permission levels to

Department of Information Technology CUIET1




the videos the admin can restrict the video access. An unregistered user can view only a

few videos. But the registered user can access more videos. The registered users include

admin, staff, parent and student.

OBJECTIVE AND SCOPE OF THE PROJECT

The main objective of our project is to create a web application exclusively for

streaming videos of the college. By providing different user classes we can provide

maximum security and privacy for these videos.

Through this web site we can view the different programs in the college if we are

not present there. Recorded videos are also supported by the system, so this application

provides an opportunity to view those programs in future.

MODULES:-

i) Streaming module

ii) Database management module

Streaming module:

This module is responsible for streaming the video through web. The videos may be live

or recorded. According to the request from client the admin can stream the video. The

recorded video will be saved in the data base of server. Live video will be streamed after

encoding.

In live video streaming the video can be selected from video capturing devices associated

with the computer. After encoding and setting permission the admin can stream this video.For encoding and streaming the video we use vlcj libraries.

Database management module:

This module is responsible for storing and processing the data of users and videos. The

database of this system contains details of different categories of users and videos access

permission is based on this user category. In the database, the administrator will set the

access permission to each video and according to this the videos will be available to each

user.





2. REQUIREMENT ANALYSIS

2.1 EXISTING SYSTEM

The technology of multimedia streaming allowing clients to view media contents without

waiting data download completely, and it support real-time video presenting for the client.

There exist different streaming systems and coding formats. There are many streaming

media services, for instance YouTube and Yahoo video.

The features of existing video streaming system are:

•

Stream video and audio live from the PC• Watch video streams from any web browser with a Flash plugin or in Windows

Media Player

• Host any number of pre-recorded video files

• Stream videos in any file format

• Stream video or jpg images from your webcam

• Pre-record video for broadcast with Debut Video Recorder

There also exist systems for live video streaming through web for news, sports etc.

2.2 PROPOSED SYSTEM:

There exist different live video streaming systems. But this system provides video

streaming exclusively for college events. The features of this system can be described as:

2.2.1 Live video broadcasting of college events:

This system will broadcast the different events in the college. Here, we designed and

constructed a live media streaming system to broadcast important activities such as:

graduation ceremonies, sport games, banquets, and seminar presentation etc.

2.2.2 Considering Support multiples transmission bit rates:

The home-user broadband connection is different, so this system must support multiple

transmission rates.





2.2.3 Only the approved users can login to this site.

Only the administrator can register the users based on the college database. After the

registration the users can collect their username and password from the administrator. So

only the registered users can login to the site. But there are some public videos which are

permitted to the unregistered users also.

2.2.4 More than one video can be broadcasted at a time.

When there are more than one program occurs at college, the administrator can stream

multiple videos at the same time by simply specifying the device URL. And the users can

select the videos from the list.

2.2.5 Support different categories of users:

This system support different categories of users such as students, parents, staffs and

others. And give permission to watch video according to the user category.

2.2.6 Opportunity to save videos.

If the registered user wishes to save the video, then the system provides opportunity

to save videos in the database of user’s account.

2.2.7 Post comments

Users can post comments about the videos.

2.3 SELECTION OF SOFTWARE

To create this tool in efficient manner, we should select correct software and language to

write the code. We have to do a web based project. So we selected Java as the core

programming language. To encode and stream the video we use a vlcj, the java binding of

videoLAN.

2.4 FEASIBILITY STUDY

Feasibility study is a procedure that identifies, describes and evaluates candidate

system and selects the best system for the job. An estimate is made of whether the identified

user needs may be satisfied using current software and hardware technologies. The study

will decide if the proposed system will be cost effective from a business point of view and





if it can be developed given existing budgetary constraints. The key considerations involved

in the feasibility analysis are economic, technical, behavioral and operational.

Economic Feasibility:

The economic analysis is to determine the benefits and savings that are expected

from a candidate system and compare them with costs. The system is economically feasible,

as the organization possesses the hardware and software resources required for the

functioning of the system. Any additional resources, if required, can also be easily acquired.

Technical Feasibility:

It centres on the existing computer system and to what extent it can support the

proposed addition. Since the minimum requirements of the system like IIS on the server and

a browser on the client, are met by any average user.

Operational Feasibility:

The system operation is the longest phase in the development life cycle of the

system. So, operational feasibility should be given much importance. The users of the

system do not need thorough training on the system. All they are expected to know to

operate the system is the basic net surfing knowledge. It has a user-friendly interface.

Behavioral Feasibility:

In today’s world, where computer is an inevitable entity, the systems like video streaming

site, which requires no special efforts than surfing the net are enjoying wide acceptance.

Thus the organization is convinced that the system is feasible.

3.3 DESCRIPTION OF LANGUAGE

3.3.1 JAVA

JAVA is an object oriented programming language and it was intended to serve as a

new way to manage software complexity. Java refers to a number of computer software

products and specifications from Sun Microsystems that together provide a system for

developing application software and deploying it in a cross-platform environment. Java

is used in a variety of computing platforms from embedded devices and mobile phones

on the low end, to enterprise servers and supercomputers on the high end. Java is nearly

everywhere in mobile phones, Web servers and enterprise applications, and while less

common on desktop computers; Java applets are often used to provide improved

functionality while browsing the World Wide Web.

The most important features of java are:





PLATFORM INDEPENDENT

The concept of Write-once-run-anywhere (known as the Platform independent) is one of

the important key feature of java language that makes java as the most powerful language.

Not even a single language is idle to this feature but java is closer to this feature. The

programs written on one platform can run on any platform provided the platform must have

the JVM.

SIMPLE

There are various features that makes the java as a simple language. Programs are easy to

write and debug because java does not use the pointers explicitly. It is much harder to write

the java programs that can crash the system but we can not say about the other

programming languages. Java provides the bug free system due to the strong memory

management. It also has the automatic memory allocation and deallocation system.

OBJECT ORIENTED

To be an Object Oriented language, any language must follow at least the four

characteristics.

• Inheritance : It is the process of creating the new classes and using the

behavior of the existing classes by extending them just to reuse the existing codeand adding the additional features as needed.

• Encapsulation : It is the mechanism of combining the information and

providing the abstraction.

• Polymorphism : As the name suggest one name multiple form, Polymorphism

is the way of providing the different functionality by the functions having the same

name based on the signatures of the methods.

• Dynamic binding: Sometimes we don't have the knowledge of objects about

their specific types while writing our code. It is the way of providing the maximum

functionality to a program about the specific type at runtime.

As the languages like Objective C, C++ fulfills the above four characteristics yet they are

not fully object oriented languages because they are structured as well as object oriented

languages. But in case of java, it is a fully Object Oriented language because object is at the

outer most level of data structure in java. No stand alone methods, constants, and variables

are there in java. Everything in java is object even the primitive data types can also be

converted into object by using the wrapper class.





ROBUST

Java has the strong memory allocation and automatic garbage collection mechanism. It

provides the powerful exception handling and type checking mechanism as compare to

other programming languages. Compiler checks the program whether there any error and

interpreter checks any run time error and makes the system secure from crash. All of the

above features make the java language robust.

DISTRIBUTED

The widely used protocols like HTTP and FTP are developed in java. Internet

programmers can call functions on these protocols and can get access the files from any

remote machine on the internet rather than writing codes on their local system.

PORTABLE

The feature Write-once-run-anywhere makes the java language portable provided that the

system must have interpreter for the JVM. Java also has the standard data size irrespective

of operating system or the processor. This feature makes the java as a portable language.

DYNAMIC

While executing the java program the user can get the required files dynamically from a

local drive or from a computer thousands of miles away from the user just by connectingwith the Internet.

SECURE

Java does not use memory pointers explicitly. All the programs in java are run under an

area known as the sand box. Security manager determines the accessibility options of a

class like reading and writing a file to the local disk. Java uses the public key encryption

system to allow the java applications to transmit over the internet in the secure encrypted

form. The byte-code Verifier checks the classes after loading.

PERFORMANCE

Java uses native code usage, and lightweight process called threads. In the beginning

interpretation of byte-code resulted the performance slow but the advance version of JVM

uses the adaptive and just in time compilation technique that improves the performance.

MULTITHREADED





As we all know several features of Java like Secure, Robust, Portable, dynamic etc; you

will be more delighted to know another feature of Java which is Multithreaded.

Java is also a multithreaded programming language. Multithreading means a single program

having different threads executing independently at the same time. Multiple threads execute

instructions according to the program code in a process or a program. Multithreading works

the similar way as multiple processes run on one computer.

Multithreading programming is a very interesting concept in Java. In multithreaded

programs not even a single thread disturbs the execution of other thread. Threads are

obtained from the pool of available ready to run threads and they run on the system CPUs.

This is how Multithreading works in Java which you will soon come to know in details in

later chapters.

INTERPRETED

We all know that Java is an interpreted language as well. With an interpreted language such

as Java, programs run directly from the source code.

The interpreter program reads the source code and translates it on the fly into computations.

Thus, Java as an interpreted language depends on an interpreter program.

The versatility of being platform independent makes Java to outshine from other

languages. The source code to be written and distributed is platform independent.

Another advantage of Java as an interpreted language is its error debugging quality. Due to

this any error occurring in the program gets traced. This is how it is different to work with

Java.

ARCHITECTURAL NEUTRAL

The term architectural neutral seems to be weird, but yes Java is an architectural neutral

language as well. The growing popularity of networks makes developers think distributed.

In the world of network it is essential that the applications must be able to migrate easily to

different computer systems. Not only to computer systems but to a wide variety of hardware

architecture and Operating system architectures as well. The Java compiler does this by

generating byte code instructions, to be easily interpreted on any machine and to be easily

translated into native machine code on the fly. The compiler generates an architecture-

neutral object file format to enable a Java application to execute anywhere on the network

and then the compiled code is executed on many processors, given the presence of the Java

runtime system. Hence Java was designed to support applications on network. This feature

of Java has thrived the programming language.





3.3.2 JSP

Java Server Pages (JSP) is a Java technology that helps software

developers serve dynamically generated web pages based on HTML, XML, or other document

types. Released in 1999 as Sun's answer to ASP and PHP, JSP was designed to address the

perception that the Java programming environment didn't provide developers with enough

support for the Web.

To deploy and run, the Apache Tomcat Server is used. It is an open source servlet container

developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and

the Java Server Pages (JSP) specifications from Sun Microsystems, and provides a "pure

Java" HTTP web server environment for Java code to run.

The main features of JSP technology are

• A language for developing JSP pages, which are text-based documents that describe

how to process a request and construct a response

• Constructs for accessing server-side objects

• Mechanisms for defining extensions to the JSP language

JSP technology also contains an API that is used by developers of Web containers.

3.3.3 Java script

JavaScript, also known as ECMAScript, is a prototype-based, object-oriented scripting

language that is dynamic, weakly typed and has first-class functions. It is also considered

a functional programming language.

JavaScript is an implementation of the ECMAScript language standard and is primarily used in

the form of client-side JavaScript, implemented as part of a web browser in order to provide

enhanced user interfaces and dynamic websites. This enables programmatic access to

computational objects within a host environment.

JavaScript's use in applications outside web pages—for example in PDF documents, site-

specific browsers and desktop widgets—is also significant. Newer and faster JavaScript VMs

and frameworks built upon them (notably Node.js) have also increased the popularity of

JavaScript for server-side web apps.

JavaScript uses syntax influenced by that of C. JavaScript copies many names and naming

conventions from Java, but the two languages are otherwise unrelated and have very different

semantics. The key design principles within JavaScript are taken from the Self and Scheme

programming languages.





3.3.4 HTML

HTML, which stands for HyperText Markup Language, is the predominant mark-up

language for web pages. HTML is the basic building-blocks of web pages.

HTML is written in the form of HTML elements consisting of tags, enclosed in angle

brackets (like <html>), within the web page content. HTML tags normally come in pairs

like <h1> and </h1>. The first tag in a pair is the start tag, the second tag is the end

tag (they are also called opening tags and closing tags). In between these tags web designers

can add text, tables, images, etc.

The purpose of a web browser is to read HTML documents and compose them into visual

or audible web pages. The browser does not display the HTML tags, but uses the tags to

interpret the content of the page.

HTML elements form the building blocks of all websites. HTML allows images and

objects to be embedded and can be used to create interactive forms. It provides a means to

create structured documents by denoting structural semantics for text such as headings,

paragraphs, lists, links, quotes and other items. It can embed scripts in languages such

as JavaScript which affect the behaviour of HTML webpage.

4. SYSTEM DESIGN

4.1 INPUT DESIGN

Inaccurate input data are most common cause of errors in data processing. Errors

entered by data entry operators can be controlled by input design. Input design is the

process of converting user-oriented inputs to a computer-based format. Input data are

collected and organized into groups of similar data.

The goal of designing input data is to make data entry easy, logical and free from

errors as possible. In the design of input the following steps must be considered.

• The allocated space for each field.

• Field sequence, which must match that in the source document.

• The format in which data fields are entered





We have to keep in mind the following things to design the system

• What data to input

• What medium to use

• The dialogue to guide users in providing input

• Methods for performing input validation and steps to follow when errors occur.

Input design is a part of overall system design which requires very careful attention.

Often the collection of input data is the most expensive part of the system, in terms of the

equipment used; it is the point of most contact for the users with the computer system; and

it is prone to error. If data going into the system is incorrect, then the processing and outputwill magnify these errors. Thus the designer has a number of clear objectives in input

design.

4.2 OUTPUT DESIGN

Outputs from computer systems are required primarily to communicate the result of

processing to users or sometimes to other systems, including machine – based systems.

They are also used to provide a permanent copy of these results for later consultation. These

are various types of output required by most systems, the main ones are:

External Output

Whose destination is outside the organization and which require special attention

because they project the image of the organization.

• Internal Outputs:

Whose destination is within the organization and which require careful design

because they are the user’s among interface with the computer.





• Operational Outputs:

Whose use is purely within the computer department, e.g. program listings, usage

statistics etc.

• Interactive Outputs:

This involves the user in communicating directly with the computer.

Output Definition

The outputs should be defined in terms – type of output, content, format, location,

sequence.

4.3 DATAFLOW DIAGRAMS

Data Flow Diagrams (DFD) is used to define the flow of the system

and its resources such as information. Data Flow Diagrams are a way of

expressing system requirements in a graphical manner. DFD represents one

of the most ingenious tools used for structured analysis. A DFD is also

known as a bubble chart. It has the purpose of clarifying system requirements

and identifying major transformations that will become programs in system

design.

In the normal convention, logical DFD can be completed using only 4

notations,

: Represents Source/destination data

: Represents data flow





: Represents a process that transforms incoming data into

outgoing flow.

: Represents data store.

The DFD at the simplest level is referred to as the ‘Context

Analysis Diagram’. These are expanded by level, each explaining its

processing detail. Processes are numbered for easy identification and are

normally labeled in block letters. Each Data flow is labeled for easy

understanding.

5. SYSTEM IMPLEMENTATION AND TESTING

5.1 SYSTEM IMPLEMENTATION

Implementation is the carrying out, execution, or practice of a plan, a method, or any design

for doing something. As such, implementation is the action that must follow any

preliminary thinking in order for something to actually happen. In order to provide live

streaming media on the Internet, a streaming media consequently consisted of videos and

audios, converting them into a streaming format, and setting up a media server to provide

real-time media transmitted through the Internet. A streaming format means that the

requested media signals are transmitted step by step from server to client

5.2 SYSTEM TESTING

System testing is intended to check whether a whole collection of modules behaves

properly-possibly on the assumption that all of its constituent modules behave properly by

themselves. At the final stage of integration testing, it coincides with system testing. The

system as a whole is tested.

The most natural and customary way of verifying any piece of work is just to operate it in

some representative situations and verify whether it behaves as expected. Software testing

is totally different from other Engineering disciplines, in that it lags the continuity property.

Testing is a critical activity in software engineering and should be performed as

systematically as possibly. There are two testing strategies 1) Testing in the Small 2)

Testing in the Large. Testing is virtual to the success of the system. A series of testing are

performed for the proposed system is ready for user acceptance testing.

TESTING IN SMALL

There are two main approaches: Whit Box testing and Black Box Testing. Asingle module

is tested as per techniques given below.

White Box Testing

This test is conducted during the code generation phase itself. All the errors were rectified

at the moment of its discovery. During this testing it is ensured that







6. SYSTEM MAINTENANCE

Maintenance of the software is one of major step in Software Engineering. System

Maintenance is the process of modifying a software system or component after its delivery

inorder to correct , improve the performance and other attributes or to adapt to the changed

environment. Maintenance covers a wide range of activities including correcting, coding

and design errors, updating the documentation and test data and updating the user support.

There is an aging process that calls for periodic maintenance of hardware and software.

Maintenance can be classified as:

• Corrective Maintenance

• Adaptive Maintenance

• Perfective Maintenance

Corrective Maintenance removes the software faults. Corrective Maintenance should be of

overriding priority for the software maintenance, which improves the system without

changing its functionality.

Adaptive Maintenance may be needed because of changing in the user requirements,

changes in the target platform or changes in the external interface. Minor adaptive changes

should be carried out as a separate development project.

The objective of perfective maintenance should be to prevent failure and optimize the

software adaptive maintenance that modifies the software to keep it up to date with its

operative.





7. FUTURE ENHANCEMENTS

Streaming technology has entered a new cycle of innovation. Content providers are

looking for new ways to reuse the content and metadata they already have. Podcasting

based on the calendar we already maintain for our website, detecting audio and video

content in their streams, creating fake live streams based on on-demand content, tieing into

their metadata databases, Streaming providers are being challenged to provide custom

solutions for the content providers who are becoming more demanding and creative with

their content.

The major disadvantage of streaming is that quality is limited by available bandwidth.

For videos to be delivered quickly to a user's desktop for viewing, two things have to be

considered: the size of the video and the Internet bandwidth available to the user. So these

would be put into enhancement and development for future. Compressing videos can

normally sacrifice their quality, and a small bandwidth normally results in choppy video

playback. Another drawback to the availability of streaming videos is the increase in

network or Internet traffic. The current stream is not perfectly fine because the streaming

speed is comparatively slow and mainly depends on the internet connection. So would

increasing the maximum streaming speed be a difficult thing to do, but hopefully someday

in the future!





8. CONCLUSION

In this project, we implemented a live video streaming system for the college. Our target is

the delivery of live video as well as recorded video streams (with audio) of different events

take place in the college to different users. With this objective, we examined the existing

(commercial and noncommercial) systems, coming up to the conclusion that none of them

meets all the requirements of our application. Therefore, we developed a system for video

streaming in a college environment using http protocol. We used the vlcj, the java binding

for Video LAN, for encoding and streaming the video. Our experimentation results the

solution for a video streaming system for colleges.

As the future directions of our project, we will implement a video streaming system which

supports high definition videos with better playback quality.
