The new AV1 format by Alliance for Open Media aims to be both industry standard, royalty-free, and open, and has wide industry support.ДЄlthough Theora is not affected by known non-free patents, Apple has expressed concern about unknown patents that might affect it, whose owners might be waiting for a corporation with extensive financial resources to use the format before suing.

The result was a polarisation of HTML5 video between industry-standard, ISO-defined but patent-encumbered formats, and open formats. This is an ongoing issue and this section will be updated once more information is available. However, there are no known codecs that satisfy all the current players: we need a codec that is known to not require per-unit or per-distributor licensing, that is compatible with the open source development model, that is of sufficient quality as to be usable, and that is not an additional submarine patent risk for large companies. It would be helpful for interoperability if all browsers could support the same codecs. User agents should support Theora video and Vorbis audio, as well as the Ogg container format. But on 10 December 2007, the HTML5 specification was updated, replacing the reference to concrete formats: Initially, Ogg Theora was the recommended standard video format in HTML5, because it was not affected by any known patents.

In addition to software decoders, a hardware video decoder should exist for the format, as many embedded processors do not have the performance to decode video.

Have good compression, good image quality, and low decode processor use.

The HTML5 Working Group considered it desirable to specify at least one video format which all user agents (browsers) should support.

User agents are free to support any video formats they feel are appropriate, but content authors cannot assume that any video will be accessible by all complying user agents, since user agents have no minimal set of video and audio formats to support. 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.
