For more information, see Technical Note TN2266 'Creating Reference Movies-MakeRefMovie' Specifying Fallback Behavior Similarly, if the source is a QuickTime reference movie, it can include alternate sources at different data rates, and Safari chooses the best source for the current bandwidth when the video is first requested (though it does not dynamically switch between sources if available bandwidth subsequently changes). For more information, see HTTP Live Streaming Overview. To provide multiple bandwidths, you must provide a src attribute that specifies a source capable of supporting data rate selection itself.ДЇor example, if one of your sources is an HTTP Live Stream, the playlist file can specify multiple streams, and Safari selects the best stream for the current bandwidth dynamically as network bandwidth changes. If you supply multiple sources, the browser chooses the first it can play based on scheme, file format, profile, and codecs. HTML5 does not support selection from multiple sources based on data rate.

Browsers that support neither m3u8 playlists nor RTSP URLs play the progressive download version. Safari on the desktop plays the RTSP stream, while Safari on iOS plays the HTTP Live stream. Listing 1-3 Specifying multiple audio sourcesДЄgain, the browser picks the first source it can handle. Listing 1-3 is a simple example of using multiple sources for an audio file. A browser that can play neither Ogg nor AAC might still be able to play the WAVE file.

A browser that cannot play AAC but can play Ogg plays the Ogg file. For example, if you have an AAC audio file, an Ogg Vorbis audio file, and a WAVE audio file, listed in that order, Safari plays the AAC file. The browser chooses the first listed source that it thinks it can play. List the alternate media sources in the order of most desirable to least desirable.

Instead of using the src attribute in the media element itself, follow the or tag with one or more elements, prior to the closing tag. The browser iterates through them until it finds one it can play or runs out of sources. Fortunately, the and elements allow you to list as many elements as you like.

Not all types of audio and video can play on all devices and browsers. Otherwise the user has no way to play the movie.

If you do not set the controls attribute, you must either set the autoplay attribute, create a controller using JavaScript, or play the movie programmatically from JavaScript. (You cannot set the attribute to false explicitly in HTML-you set it to false implicitly by leaving the attribute out.) In cases where it is crucial that the bottom of the video never be obscured, omit the controls attribute. The controller is not normally visible when the movie is playing-it appears only when the movie is paused, when the user touches the video, or when the mouse pointer hovers over the playing movie. In Safari, the default video controller is slightly translucent and is overlaid on the bottom of the video. If neither is specified, the video is displayed at its native size. If both height and width are specified, the video is presented at that size. If only the height or width parameter is specified, the video is scaled up or down to that height or width while maintaining the native aspect ratio of the movie. In Safari on the desktop, the movie metadata is downloaded automatically whenever possible, so the native video size is used as the default. On iPhone or iPod touch, the video plays in fullscreen mode once the user initiates it, and the default space is allocated to a placeholder on the webpage. On iPad, the video currently plays in this default space. If no height or width is specified, a default size of 150 x 300 pixels is allocated in the webpage. In Safari on iOS, the native size of the video is unknown until the user initiates a download.
