How to embed video in HTML5?

With the continuous development of the Internet, video has become a mainstream way for people to obtain information and entertainment. In web design, embedded video has also become an important part. In the past, embedding videos required relying on Flash or other plug-ins, but these plug-ins not only took up a lot of bandwidth and resources, but also had some security issues. But HTML5 provides a more concise, efficient and safe way to embed videos without relying on any plug-ins.

Generally speaking, HTML5 embedded video requires the use of video tags and source tags. Among them, the video tag defines the area of ​​a video player, and the source tag defines the video file to be played and its format. The following is a sample code for a simple video tag:

<video src="video.mp4" controls>
    您的浏览器不支持HTML5视频播放器。
</video>

In this example, we define a video tag whose src attribute points to a video file named video.mp4. The control panel displays the following It prompts the user that if the browser does not support the HTML5 video player, the video cannot be played. It should be noted that in this tag, we also use the controls attribute to display the control panel of the video player, where users can pause, play, jump to various positions in the video, and adjust the video volume and other functions.

However, in addition to the mp4 format in the above example code, HTML5 video also supports a variety of other common video formats, such as WebM, Ogg, etc. In order to ensure browser compatibility, we usually need to specify a source tag for each video file in the source tag. The following is a more detailed HTML5 video embedding example:

<video width="640" height="480" controls>
    <source src="video.mp4" type="video/mp4">
    <source src="video.webm" type="video/webm">
    <source src="video.ogg" type="video/ogg">
    您的浏览器不支持HTML5视频播放器。
</video>

In this example, we set the width and height of the video tag to define the size of the video player. Below it, we specify a source tag for each video file and write the respective video format and MIME type. Finally, we also placed an alternative text within the video tag to remind users what to do if the video cannot be played.

It should be noted that HTML5 video is well supported on most mobile devices, but for older or browsers that do not support HTML5, you may need to consider using Flash or other plug-ins to implement video. Play. In addition, in order to improve the performance and quality of video playback, we can also use JavaScript code to control video playback, pause, jump, and automatic playback functions.

In short, embedding videos through HTML5 can provide a more efficient, concise, and safe video playback method, helping us better present and deliver visually impactful content.
