Youku SolutionThe easiest way to display videos in HTML is to use a video website such as Youku.
If you want to play a video on a web page, you can upload the video to a video website such as Youku, and then insert HTML code into your web page to play the video:
<embed src="http://player.youku.com/player.php/sid/XMzI2NTc4NTMy/v.swf" width="480" height="400" type=" application/x-shockwave-flash"> </embed>
##Example
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>php中文网(php.cn)</title> </head> <body> <h2>播放视频</h2> <embed src="http://player.youku.com/player.php/sid/XMzI2NTc4NTMy/v.swf" width="480" height="400" type="application/x-shockwave-flash"> </embed> </body> </html>Try running the program
Using hyperlinks
If a web page contains hyperlinks to media files, most browsers will use "Helper application" to play files. The following code snippet displays a link to an AVI file. If the user clicks the link, the browser will launch a "auxiliary application", such as Windows Media Player, to play the AVI file:<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>php中文网(php.cn)</title> </head> <body> <h2>点击这个链接打开查看</h2> <a href="Uploader.swf">播放视频文件</a> </body> </html>Find a video file and try it
A note about inline videos
When a video is included in a web page, it is called an inline video. If you plan to use inline video in a web application, you need to be aware that many people find inline video annoying. Also note that users may have turned off the inline video option in their browser. Our best advice is to only include inline videos in places where users expect to see them. A positive example is when a user needs to see a video and clicks on a link, which opens the page and then plays the video.#HTML Multimedia Tag
