The HTML5 specification does not specify which video and audio formats browsers should support. The MIME type denotes the container format of the file, and the container format defines the interpretation of the codec string.

The "type" attribute specifies the MIME type and possibly a list of codecs, which helps the browser to determine whether it can decode the file without beginning to download it. Alternatively, the JavaScript canPlayType() function can be used to achieve the same. Using any number of elements, as shown below, the browser will choose automatically which file to download. The "video" element supports fallback through specification of multiple sources. The browser in question "knows best" what formats it can use. For other features, browser sniffing is used sometimes, which may be error-prone: any web developer's knowledge of browsers will inevitably be incomplete or not up-to-date. Video format support varies among browsers (see below), so a web page can provide video in multiple formats.
Its purpose is to be representative of the video. The optional "poster" attribute specifies an image to show in the video's place before playback is started.
Alternatively, playback can be controlled with JavaScript, which the web designer can use to create a custom user interface. The "controls" attribute enables the browser's own user interface for controlling playback. This is fallback content to display for user agents that do not support the video tag.
