Hindi
भारत का शैक्षिक इतिहास अत्यधिक समृद्ध है। प्राचीन काल में ऋषि-मुनियों द्वारा शिक्षा मौखिक रूप में दी जाती थी। वर्णमाला के विकास के पश्चात शिक्षा का प्रसार भोज पत्र और पेड़ों की छालों पर लिखित रूप में होने लगा। इस कारण भारत में लिखित साहित्य का विकास तथा प्रसार होने लगा। बौद्ध धर्म के प्रचार के साथ-साथ देश में शिक्षा जन साधारण को उपलब्ध होने लगी। नालन्दा, विक्रमशिला और तक्षशिला जैसी विश्व प्रसिद्ध शिक्षा संस्थानों की स्थापना ने शिक्षा के प्रचार में अहम भूमिका निभाई। तदुपरांत, भारत में अंग्रेजों के आगमन से युरोपीय मिशनरियों ने अंग्रेजी शिक्षा का प्रचार किया। इसके बाद से भारत में पश्चिमी पद्धति का निरन्तर प्रसार हुआ है।

वर्तमान समय में भारत में सभी विषयों के शिक्षण हेतु अनेक विश्वविद्यालय और उनसे जुड़े़ हजा़रों महाविद्यालय हैं। भारत ने उच्च कोटि की उच्चतर शिक्षा प्रदान करने वाले विश्व के अग्रणी देशों में अपना स्थान बना लिया है।

परन्तु अनेक कारणों से शिक्षा(विशेष रूप से व्यावसायिक शिक्षा )के शुल्क में निरन्तर वृद्धि हो रही है। इस कारण गरीब परिवार के बच्चों को उच्च शिक्षा प्राप्त करने में कठिनाई होने लगी है। अ‌तः इन परिस्थितियों में विकी ऐड्युकेटर के निशुल्क पाठ्यक्रम की महत्ता बढ़ जाती है।

Wikipedia uses Ogg Theora for video because it is open and royalty-free. Because most popular movie/audio formats are patented and require a royalty, there are no free all purpose video converters. See also WikiCommons' Theora video conversion help page.

Limitations and Implementation Issues

 * Both the Wikipedia project and the Wikimedia Commons limit uploads to a maximum of 100 megabytes.
 * There is currently no standard for acceptable streaming bitrates in articles. For the widest broadband compatibility, a bitrate of no more than 220 kilobits/sec will work for users of 256 kilobit DSL. Very high bitrates near or over 1,000 kilobits/sec may outstrip the ability of Wikipedia or the Commons to deliver the streaming data fast enough.
 * Resizing a video to use a smaller thumbnail does not change the bitrate or bandwidth requirements. A video recorded at 640x480 but shown in an article at 160x120 will still stream all the data that would be used to display it at the 640x480 size. If you need a smaller video size in an article for some reason, you are much better off to just recompress the larger video to the smaller size to bake in the bandwidth savings. Better quality can be obtained in these small videos, by having the original uploader create the smaller size using their original uploaded content.

A template to make this technical issue more prominent in articles is available as: -- this same template also exists in the Wikimedia Commons for insertion into video upload descriptions.

An example usage of this template can be seen in the video File:Rhof-histWaschmaschine.ogg on the Wikimedia Commons. This page also includes links to smaller, low bitrate, downsampled versions of the video.

Offering multiple bit-rates
There is currently no defined method to offer readers multiple video versions, in order to select a quality and speed most suitable for their network bandwidth. While any video may be fully downloaded first for local playback, streaming of video requires that the file size be small enough to be reliably streamed continuously to the user within their bandwidth limits.

One possible option for offering multiple bitrates is shown here. This is a custom wikitable and is used in the washing machine article to showcase use of a vintage washing machine.

There is no predefined ready-to-use template for creating a multi-bitrate thumbnail like this and there is no built-in facility provided by Wikimedia to automatically downsample video into various smaller thumbnail versions with lower bitrates.

If you intend to offer multiple bitrates to readers you will need to construct a custom wikitable similar to this one which references each derivative transcoded low-bitrate version.

Useful software
For assistance with conversion, consider contacting the following editors:
 * Firefogg.org offers a web UI for transcoding video into ogg theora. Alternatively the mwEmbed gadget can be used to enable firefogg on the commons upload page.
 * For video, ffmpeg2theora is a command line encoder capable of converting numerous file formats (.mov, .mpg, .mpeg, .avi) into Ogg Theora. It works on Windows, Macintosh, and Linux/Unix. (how to use ffmpeg2theora.)
 * You can also use the encoder_example application included with libtheora in combination with a program like MPlayer that is capable of dumping raw (yuv4mpeg) video and sound to encode in Ogg Theora
 * http://programmer-art.org/projects/arista-transcoder and http://www.linuxrising.org/transmageddon/ are graphical transcoders for Unix / Linux
 * LiVES and Cinelerra are video editing programs for Linux which are able to edit Ogg Theora videos
 * The directshow filters can be used to encode Ogg Theora using GraphEdit.
 * The Xiph.org wiki has a list of Theora Software Encoders
 * handbrake is a free (GPL'd) transcoder for Windows, Mac and Linux

Video usage


The easiest way to embed video directly into an article is by using the same tag as for image files. The result is on the right.



By default, a frame from the midpoint of the video is used for the initial still image. To use a different frame, use the thumbtime parameter. For instance:



Specify the time in seconds, or use colons to separate hours, minutes and seconds.

To just give a link to the video, use:
