See Replacing a Media Source Sequentially for details. You can change the audio or video source dynamically, however. Playing multiple simultaneous audio streams is also not supported. Playing more than one video-side by side, partly overlapping, or completely overlaid-is not currently supported on iOS devices. Multiple Simultaneous Audio or Video StreamsĬurrently, all devices running iOS are limited to playback of a single audio or video stream at any time. Earlier versions of iPhone support H.264 Baseline profile 3.0. IPad and iPhone 3G and later support H.264 Baseline profile 3.1. Safari on iOS (including iPad) currently supports MPEG-4 video (Baseline profile) and QuickTime movies encoded with H.264 video (Baseline profile) and one of the supported audio types. Safari on iOS (including iPad) currently supports uncompressed WAV and AIF audio, MP3 audio, and AAC-LC or HE-AAC audio. This includes media encoded using codecs QuickTime does not natively support, provided the codecs are installed on the user’s computer as QuickTime codec components. Safari on the desktop supports any media the installed version of QuickTime can play. It is especially important to provide user controls on iPad because autoplay is disabled to prevent unsolicited cellular download. On the desktop or iPad, you must either include the controls attribute or provide playback controls using JavaScript.
Media Playback ControlsĬontrols are always supplied during fullscreen playback on iPhone and iPod touch, and the placeholder allows the user to initiate fullscreen playback. On the desktop and iPad, the first frame of a video displays as soon as it becomes available. If the iOS device cannot play the specified media, there is a diagonal bar through the control, indicating that it cannot play. The placeholder provides a way for the user to play the media. The placeholder is translucent, so the background or any poster image shows through. On iPhone and iPod touch, a placeholder with a play button is shown until the user initiates playback, as shown in Figure 2-1.
Currently, the default height and width do not change when the movie loads, so you should specify the preferred height and width for the best user experience on iOS, especially on iPad, where the video plays in the allocated space. For more information about the Web Audio API, read the next chapter, Playing Sounds with the Web Audio API.īecause the native dimensions of a video are not known until the movie metadata loads, a default height and width of 150 x 300 is allocated on devices running iOS if the height or width is not specified.
