youtube clone is a popular free video sharing web site which lets users upload, view, and share video clips. Founded in February 2005 by three early employees of PayPal, the San Mateo-based service utilizes Adobe Flash technology to display video. The wide variety of site content includes movie and TV clips and music videos, as well as amateur content such as videoblogging. Despite YouTube’s huge user base, content library, and hit count popularity, it is still a very small company at the administrative level, staffed by only about 60 employees.[1]

Introduction
[edit]

Background

YouTube,Inc. was founded by Chad Hurley, Steve Chen, and Jawed Karim, who were all early employees of PayPal.[2] Prior to PayPal, Hurley studied design at Indiana University of Pennsylvania. Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign.[3] The domain name “youtube clone.com” was activated on February 15, 2005,[4] and the website was developed over the following months. The creators offered the public a preview of the site in May 2005, and six months later, youtube clone made its official debut.

The company’s humble beginnings in a garage and commitment to offering free services necessitated outside financial backing. In November of 2005, venture capital firm Sequoia Capital invested an initial $3.5 million;[5] additionally, Roelof Botha, partner of the firm and former CFO of PayPal, joined the youtube clone board of directors. In April 2006, Sequoia put an additional $8 million into the company, which had experienced a boom of popularity and growth in just its first few months.[6]
[edit]

Video uploads

About 65,000 videos are uploaded on the site each day. They include things such as music, video games and more. Videos can be uploaded for free, as long as they are 100MB or less and do not contain copyrighted material. A registered account is needed to add the videos.
[edit]

Service

The slogan “Broadcast Yourself” reflects the basic intent of the site’s creators: to provide hosting for videos. Visitors are encouraged to register an account, which allows them to upload videos as well as view them. For example, personal content like home movies can be shared with family and friends, or amateur filmmakers can hope to gain a larger audience for their work. Video as a blogging medium has especially increased in popularity because of youtube clone (and led to minor celebrity for some bloggers, such as Nornna). It is also suggested that internet video be considered a legitimate choice next to more traditional media, and possibly better, given the increased potential for customized content. [citation needed]

Apart from original work, and in spite of site policy against copyright infringement, the site is also host to many clips from traditional media. This content ranges from works such as fan-created music videos and dubbed parodies, which have at least some degree of originality, to whole and/or unaltered scenes, commercials, music videos, short films, and so on. As with the music community’s conflict over filesharing, there is debate as to whether this practice may prove beneficial to the copyright holders, or simply cause harm.
[edit]

Facts and stats
[edit]

Popularity

At present, youtube clone is one of the fastest-growing websites on the World Wide Web,[7] and is ranked as the 10th most popular website on Alexa, far outpacing even MySpace’s growth.[8] According to a July 16, 2006 announcement, 100 million clips are viewed daily on YouTube, with an additional 65,000 new videos uploaded per 24 hours. The site has almost 20 million visitors each month, according to Nielsen/NetRatings,[9] where around 44% are female, 56% male, and the 12-17 year old age group is dominant.[10]
[edit]

Valuation

Although YouTube’s clone potential market value in an acquisition is pure speculation, an article in the New York Post suggested on July 23, 2006 that youtube clone may be worth anywhere from $600 million to $1 billion.[11] On August 22, 2006 the Web 2.0 blog Techcrunch suggested that Grouper’s acquisition price of $65 million implies a youtube clone valuation of approximately $2 billion. [2] On August 24 2006 an article on CNET’s News.com exclaimed “youtube clone could be a steal at $1 billion.”[12]
[edit]

Word spreads and traditional media take notice

In its short time on the web, youtube clone has grown quickly and received much attention. Online word-of-mouth has been primarily responsible for YouTube’s clone growth since its inception, and gave the site its first surge of publicity when it hosted the popular Saturday Night Live short Lazy Sunday.[13] However, YouTube’s official policy prohibits submission of copyrighted material, and NBC Universal, owners of SNL, soon decided to take action.

In February 2006, NBC asked for the removal of some of its copyrighted content from YouTube, including Lazy Sunday and 2006 Olympics clips.[5][14] The following month, in an attempt to strengthen its policy against copyright infringement, youtube clone set a 10-minute maximum limit on video length (except for content submitted via its Director Program, which specifically hosts original material by amateur filmmakers). However, the real cutoff is 10:58. This restriction is often circumvented by uploaders, who instead split their original video into smaller segments, each shorter than the 10-minute limit.
[edit]

TV networks see potential

Though youtube clone had done its part to comply with NBC’s demands, the incident made the news, giving youtube clone its most prominent publicity yet. As the site continued to grow, NBC began to realize the possibilities, and in June 2006 made an unusual move. The network had reconsidered its actions and was announcing a strategic partnership with youtube clone. Under the terms of the partnership, an official NBC channel will be set up on youtube clone, showcasing promotional clips for the series The Office. youtube clone will also promote NBC’s videos throughout its site.[15]

CBS, which had previously also asked youtube clone to remove several of its clips, followed suit in July 2006. In a statement indicative of how the traditional media industry’s perception of youtube clone (and similar sites) has changed, Sean McManus, president of CBS News and Sports noted:

youtube clone
Our inclination now is, the more exposure we get from clips like that, the better it is for CBS News and the CBS television network, so in retrospect we probably should have embraced the exposure, and embraced the attention it was bringing CBS, instead of being parochial and saying ‘let’s pull it down.’[16]

youtube clone

In August of 2006, youtube clone announced that, within 18 months, it hopes to offer every music video ever created, while still remaining free of charge. Warner Music Group and EMI have confirmed that they are among the companies in talks to implement this plan.[17] In September Warner Music and youtube clone signed a deal, in which youtube clone will be allowed to host every music video Warner produced while sharing a portion of the advertisement income. Additionally, user created videos on youtube clone will be allowed to use Warner songs in their soundtracks.[18]
[edit]

New problems arise

In spite of having formed productive relationships with several major media companies, YouTube’s clone copyright controversies are still not over. TV journalist Robert Tur filed the first lawsuit against the company in summer 2006, alleging copyright infringement for hosting a number of famous news clips without permission. The case has yet to be resolved.[19][20]
[edit]

Accessibility

* On youtube clone: Users may submit videos in several common file formats (such as .mpeg and .avi). youtube clone automatically converts them to Flash Video (with extension .flv) and makes them available for online viewing. Flash Video is a popular video format among large hosting sites due to its wide compatibility.

* Outside youtube clone: Each video is accompanied by the full HTML codes for linking to it and/or embedding it within another page; a small addition to the code for the latter will make the video autoplay when the page is accessed. These simple cut-and-paste options are popular particularly with users of social/networking sites. Poor experiences have however been cited by members of such sites,[21] where autoplaying embedded youtube clone videos has been reported to slow down page loading time or even to cause browsers to crash.

* General Concerns: Videos can be downloaded off YouTube’s clone website and viewed offline with various video player applications; however, this may be a violation of copyright.

* Download Quality: With the update to Flash Gui file formats, youtube clone has had problems with videos loading altogether on the Internet Explorer and Firefox web browsers. No news has been given for when this will be repaired.

[edit]

youtube clone policy does not allow content to be uploaded by anyone not permitted by copyright law to do so, and the company frequently removes uploaded infringing content. Nonetheless, a large amount of it continues to be uploaded. Generally, unless the copyright holder reports them, youtube clone only discovers these videos via indications within the youtube clone community through self-policing. The primary way in which youtube clone identifies the content of a video is through the search terms that uploaders associate with clips. Some users have taken to creating alternative words as search terms to be entered when uploading specific type of files (similar to the deliberate misspelling of band names on MP3 filesharing networks). For a while, members could also report one another. The service offers a flagging feature, intended as a means for reporting questionable content, including that which might constitute copyright infringement. However, the feature can be susceptible to abuse; for a time, some users were flagging other users’ original content for copyright violations, purely out of spite. youtube clone proceeded to remove copyright infringement from the list of offenses flaggable by members.
[edit]

Revenue model

youtube clone states that its business model is advertising-based. Some industry commentators have speculated that YouTube’s running costs — specifically the bandwidth required — may be as high as US$1 million per-month,[22] thereby fuelling criticisms that the company does not have a viably implemented business model. Advertisements were launched on the site beginning in March 2006. In April, YouTube started using Google AdSense.
[edit]

Violence

On their 6:30 PM bulletin on June 1, 2006, ITV News in the UK reported that YouTube and sites like it were encouraging violence and bullying amongst teenagers, who were filming fights on their mobile phones (see happy slapping), and then uploading them to YouTube. While the site provides a function for reporting excessively violent videos, the news report stated that communication with the company was difficult.[23]

Streaming media
From Wikipedia, the free encyclopedia
(Redirected from Video streaming)
Jump to: navigation, search

Streaming media is media that is consumed (heard or viewed) (mostly in the form of clips) whilst it is being delivered. Streaming is more a property of the delivery system than the media itself. The distinction is usually applied to media that are distributed over computer networks; most other delivery systems are either inherently streaming (radio, television) or inherently non-streaming (books, video cassettes, audio CDs).

The word “stream” is also used as a verb, meaning to deliver streaming media.

The remainder of this article discusses technology for streaming media over computer networks.

[edit]

History

Attempts to display media on computers date back to the earliest days of computing, in the mid-20th century. However, little progress was made for several decades, due primarily to the high cost and limited capabilities of computer hardware.

Academic experiments in the 1970s proved out the basic concepts and feasibility of streaming media on computers.

During the late 1980s, consumer-grade computers became powerful enough to display various media. The primary technical issues with streaming were:

* having enough CPU power and bus bandwidth to support the required data rates
* creating low-latency interrupt paths in the OS to prevent buffer underrun

However, computer networks were still limited, and media was usually delivered over non-streaming channels, such as CD-ROMs.

The late 1990s saw:

* greater network bandwidth, especially in the last mile
* increased access to networks, especially the Internet
* use of standard protocols and formats, such as TCP/IP, HTTP, and HTML
* commercialization of the Internet

These advances in computer networking combined with powerful home computers and modern operating systems to make streaming media practical and affordable for ordinary consumers.

In general, multimedia content is large, so media storage and transmission costs are still significant; to offset this somewhat, media are generally compressed for both storage and streaming.

A media stream can be on demand or live. On demand streams are stored on a server for a long period of time, and are available to be transmitted at a user’s request. Live streams are only available at one particular time, as in a video stream of a live sporting event.
[edit]

Streaming bandwidth and storage

Streaming media storage size (in the common file system measurements megabytes, gigabytes, terabytes, and so on) is calculated from streaming bandwidth and length of the media with the following formula (for a single user and file):

storage size (in megabytes) = length (in seconds) · bit rate (in kbit/s) / 8,388.608

\mathrm{size (MB) = \left (length(s) \cdot bit\ rate\left ({kbit \over s} \right ) \right ) \cdot {1000\ bit \over 1\ kbit} \cdot {1\ byte \over 8\ bits} \cdot {1\ MB \over 1,048,576\ bytes}}

(since 1 megabyte = 8 * 1,048,576 bits = 8,388.608 kilobits)

Real world example:

One hour of video encoded at 300 kbit/s (this is a typical broadband video for 2005 and it’s usually encoded in a 320×240 pixels window size) will be:

(3,600 s · 300 kbit/s) / 8,388.608 = 128.7 MB of storage

if the file is stored on a server for on-demand streaming. If this stream is viewed by 1,000 people, you would need

300 kbit/s · 1,000 = 300,000 kbit/s = 300 Mbit/s of bandwidth

This is equivalent to 125.68 GiB per hour.
[edit]

Protocol issues

Designing a network protocol to support streaming media raises many issues.

Datagram protocols, such as the User Datagram Protocol (UDP), send the media stream as a series of small packets. This is simple and efficient; however, packets are liable to be lost or corrupted in transit. Depending on the protocol and the extent of the loss, the client may be able to recover the data with error correction techniques, may interpolate over the missing data, or may suffer a dropout.

The Real Time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP) and the Real-time Transport Control Protocol (RTCP) were specifically designed to stream media over networks. The latter two are built on top of UDP.

Reliable protocols, such as the Transmission Control Protocol (TCP), guarantee correct delivery of each bit in the media stream. However, they accomplish this with a system of timeouts and retries, which makes them more complex to implement. It also means that when there is data loss on the network, the media stream stalls while the protocol handlers detect the loss and retransmit the missing data. Clients can minimize the effect of this by buffering data for display.

Another issue is that firewalls are more likely to block UDP-based protocols than TCP-based protocols.

Unicast protocols send a separate copy of the media stream from the server to each client. This is simple, but can lead to massive duplication of data on the network. Multicast protocols undertake to send only one copy of the media stream over any given network connection, i.e. along the path between any two network routers. This is a more efficient use of network capacity, but it is much more complex to implement. Furthermore, multicast protocols must be implemented in the network routers, as well as the servers.

As of 2005, most routers on the Internet do not support multicast protocols, and many firewalls block them. Multicast is most practical for organizations that run their own networks, such as universities and corporations. Since they buy their own routers and run their own network links, they can decide if the cost and effort of supporting a multicast protocol is justified by the resulting bandwidth savings.

Peer-to-peer (P2P) protocols arrange for media to be sent from clients that already have them to clients that do not. This prevents the server and its network connections from becoming a bottleneck. However, it raises technical, performance, quality, business, and legal issues.

Newer camcorders stream video to a computer over a FireWire connection. This uses a system of time-based reservations to ensure throughput, and can be received by multiple clients at once.
[edit]

Testing issues

Widespread deployment of streaming media raises scaling and Quality of Service issues. Testing service deployments is a significant problem. Vendors offer equipment to test streaming services across a number of test domains including Scalability, Quality of Service, Quality of experience, and protocol conformance.
[edit]

Social and legal issues

Some streaming broadcasters use streaming systems that interfere with the ability to record streams for later playback, either inadvertently, through poor choice of streaming protocol, or deliberately, because they believe it is to their advantage to do so. Broadcasters may be concerned that copies will result in lost sales or that consumers may skip commercials. Whether users have the ability and the right to record streams has become a significant issue in the application of law to cyberspace.

In principle, there is no way to prevent a user from recording a media stream that has been delivered to their computer. Thus, the efforts of broadcasters to prevent this consist of making it inconvenient, or illegal, or both.

Broadcasters can make it inconvenient to record a stream, for example, by using unpublished data formats or by encrypting the stream. Of course, data formats can be reverse engineered, and encrypted streams must be decrypted with a key that resides—somewhere—on the consumer’s computer, so these measures are security through obscurity, at best.

Efforts to make it illegal to record a stream may rely on copyrights, patents, license agreements, or—in the United States—the DMCA.

FLV
From Wikipedia, the free encyclopedia
Jump to: navigation, search
FLV Image:FlashVideo.png
File extension: .flv
MIME type: video/x-flv
Developed by: Adobe Systems (originally developed by Macromedia)
Type of format: media container

FLV (Flash Video) is a file format used to deliver video over the Internet to the Adobe Flash Player version 6, 7, 8, or 9. FLV content may also be embedded within SWF files. Notable users of the FLV format include Google Video, Reuters.com and YouTube. Flash Video is viewable on most operating systems, via the widely-available Macromedia Flash Player and web browser plug-in, or one of several third-party programs such as Media Player Classic (with the ffdshow codec installed), MPlayer, or VLC media player.

Flash Player

The Adobe Flash Player is a multimedia and application player created and distributed by Macromedia. It plays SWF files which can be created by the Adobe Flash authoring tool, Adobe Flex or a number of other Adobe and third party tools. It has support for a programing language called ActionScript, which can be used to display Flash Video from an SWF file. Because the Flash Player runs as a browser plug-in, it is possible to embed Flash Video in web pages and view the video within a web browser.
[edit]

Video Format

Most FLV files use a variant of H.263 to encode the video. Some FLV files may instead use the screen codec, a simple animation composed of a sequence of screenshots. Flash Player 8 also supports On2 Technologies’ VP6 codec. Support for encoding FLV files with the VP6 codec is provided by an encoding tool included with Adobe’s Macromedia Flash Professional 8 product, On2’s Flix encoding tools, Sorenson Squeeze, and some other third party tools.

FLV files may contain audio in PCM, ADPCM, or MP3 format. FLV is limited to one video and one audio stream per file.
[edit]

Delivery options

FLV files can be delivered in three different ways:

* Embedded in a SWF file using the Flash authoring tool (supported in Flash Player 6 and later)
* Streamed via RTMP to the Flash Player using the Flash Media Server (formerly called Flash Communication Server) , VCS ( Video Communication Server from Onlinelib VCS or the open source Red5 server
This is the best option for allowing advanced seek capabilities and automatic bandwidth detection.
* Progressively downloaded via HTTP (supported in Flash Player 7 and later.)
* Downloaded from programs like Replay A/V or WM Recorder, or from sites like Keepvid.com.

FFmpeg is a collection of free software that can record, convert and stream digital audio and video. It includes libavcodec, a leading audio/video codec library. FFmpeg is developed under Linux, but it can be compiled under most operating systems, including Windows. The project was started by Gerard Lantau, an alterego of Fabrice Bellard, and is now maintained by Michael Niedermayer. It is notable that most FFmpeg developers are part of either the MPlayer, xine or VideoLAN project as well.

The project is made of several components:

* ffmpeg is a command line tool to convert one video file format to another. It also supports grabbing and encoding in real time from a TV card.
* ffserver is an HTTP (RTSP is being developed) multimedia streaming server for live broadcasts. Time shifting of live broadcast is also supported. Note that this is very buggy and unlikely to work.
* ffplay is a simple media player based on SDL and on the FFmpeg libraries.
* libavcodec is a library containing all the ffmpeg audio/video encoders and decoders. Most codecs were developed from scratch to ensure best performance and high code reusability.
* libavformat is a library containing demuxers and muxers for audio/video container formats.
* libavutil is a helper library containing routines common to different parts of FFmpeg.

FFmpeg is released under GNU Lesser General Public License or GNU General Public License (depending on which sub-libraries one would include). The project is hosted at MPlayerHQ and makes formal releases every now and then. FFmpeg developers recommend that one should use the latest Subversion copy as development maintains a constantly stable trunk.

FFmpeg have reverse-engineered and reimplemented, among others:

* The Sorenson 3 Codec used by many QuickTime movies
* Advanced Streaming Format
* Windows Media Audio
* Windows Media Video (and thereby also the associated DivX hack)
* QDesign Music Codec 2, used by many QuickTime movies prior to QuickTime 7.

MPlayer is a free and open source media player distributed under the GNU General Public License. The program is available for all major operating systems, including Linux and other Unix-like systems, Microsoft Windows and Mac OS X.

MPlayer is known to support more multimedia formats than any other player. In addition to its wide range of supported formats MPlayer can also save all streamed content to a file. A companion program, MEncoder, can take an input stream or file and transcode it into several different output formats, optionally applying various transforms along the way.

MPlayer is a command line application which has different optional GUIs for each of its supported operating systems. Commonly used GUIs are GMPlayer (an X Window System GUI for GNU/Linux and other Unix-like systems), MPlayer OS X (for Mac OS X), MPUI (for Windows) and WinMPLauncher (also for Windows). Several alternative GUI frontends are also available for each platform.

Development

Development of MPlayer began in 2000. The original author, Árpád Gereöffy (known as A’rpi / Astral in the demoscene), was soon joined by many other programmers. In the beginning most developers were from Hungary, but nowadays the developers come from all over the world. Alex Beregszászi has maintained MPlayer since 2003 when Árpád Gereöffy left MPlayer development to begin work on a second generation MPlayer. The MPlayer G2 project is currently paused for a number of reasons. [citation needed]

MPlayer was previously called “MPlayer - The Movie Player for Linux” by its developers but this was later shortened to “MPlayer - The Movie Player” after it was made available for multiple operating systems.

Supported media formats

* Physical media: CDs, DVDs, Video CDs
* Container formats: 3gp, AVI, ASF, FLV, Matroska, MOV (QuickTime), MP4, NUT, Ogg, OGM, RealMedia
* Video codecs: 3ivx, Cinepak, DivX, DV, H.263, H.264/MPEG-4 AVC, HuffYUV, Indeo, MJPEG, MPEG-1, MPEG-2, MPEG-4, RealVideo, Sorenson, Theora, WMV, XviD
* Audio codecs: AAC, AC3, ALAC, AMR, FLAC, MP3, RealAudio, Shorten, Speex, Vorbis, WMA

MPlayer also supports a variety of different output drivers for displaying video, including X11, DirectX, Quartz Compositor, VESA, SDL and rarer ones such as ASCII art and Blinkenlights. It can also be used to display TV from a TV card using the device tv://channel.

Legal issues

Most video and audio codecs are supported natively through the libavcodec library of the FFmpeg project. For those codecs where no open source decoder has been implemented yet MPlayer relies on binary codecs. It can even use Windows DLLs directly with the help of a DLL loader forked from avifile (which itself forked its loader from the Wine project).

The combination of CSS decryption software, Windows codec use, implementation of codecs covered by software patents, and the GPL places a fully-functional MPlayer in the legal bind shared by most open source multimedia players. In the past MPlayer used to include OpenDivX, a GPL-incompatible decoder library. For these reasons MPlayer is not included in most GNU/Linux distributions with a strong commitment to free software; for example, it is not supported by Debian.
