Class s7sdk.video.VideoPlayer

The VideoPlayer is a video viewing component that displays a MP4 or Adaptive Video Set video served by Adobe Scene7. Depending on system capabilities and on the value of the playback modifier, it uses either hls-video or the native HTML video element. HTTP streaming video is used whenever the user's device supports it, with fall back to progressive video.

Video playback is controlled by clicking (or tapping) on the video if enabled using a singleClick modifier, or by using API methods and external video UI controls supplied with the SDK, such as ControlBar, PlayPauseButton, FullScreenButton, MutableVolume and VideoScrubber. Alternatively, native HTML5 video controls can be enabled using the following modifier: playback=progressive,1.

Information about the video and the state of the video playback can be obtained from the various VideoEvent events dispatched by the VideoPlayer, and/or the methods available in its API. For example, video duration can be obtained using the getDuration() method and/or by handling the NOTF_DURATION event; the current play head position is available through the getCurrentTime() method and the NOTF_CURRENT_TIME and NOTF_SEEK events; the state of the media preloading (in progressive mode) can be read via the getLoadedPosition() method and the NOTF_LOAD_PROGRESS event. Current volume can be retrieved using the getVolume() method and the NOTF_VOLUME event.

The component also dispatches a convenience CapabilityStateEvent.NOTF_VIDEO_CAPABILITY_STATE events whenever any of video capabilities listed in VideoCapabilityState changes. This event in particular is very useful for controlling the state of external UI controls like PlayPauseButton.

The VideoPlayer component provides a convenience API for describing underlying system restrictions related to video playback. The supportsInline() method identifies whether the system can play video inline; in the case when inline playback is not possible (like on some mobile phones), external UI elements like VideoScrubber are not needed on the page. The supportsVolumeControl() tells whether programmatic volume control is possible; on mobile devices volume is normally controlled using hardware buttons only, so MutableVolume should be hidden in that case.

In order to implement a full screen video experience, the VideoPlayer should be embedded into the Container component; Container provides an API and support for full screen mode.

The VideoPlayer component supports playback of video content hosted outside of Scene7 or Dynamic Media. If the path portion of URL to such external video ends with .m3u8 then the component automatically selects HLS playback type, otherwise progressive playback will be used. Effectively VideoPlayer ignores the value of playback modifier when working with external video. External video can be set using video modifier or setVideo() API method.

Customizing Behavior Using Modifiers

Modifiers change VideoPlayer default behavior. They are passed to the component by the ParameterManager instance specified in the constructor.

The following modifiers are supported:

Defining the Appearance using CSS

You can define the appearance of the VideoPlayer component using CSS rules. All HTML5 Viewer SDK components use class selectors for styling. You can style the body of the VideoPlayer component by using the .s7videoplayer class selector. The styles that are associated with this class selector are applied to all instances of the VideoPlayer component. You can style particular instances by prefixing the class rule with the instance #id. For example, styling rules for #myComp.s7videoplayer are applied only to the particular VideoPlayer instance.

The styling of the sub-elements using class selectors like .s7iconeffect for example, must be specified in the form of the descendant class selectors. That is, they must follow the main class selector separated by a space, such as .s7videoplayer .s7iconeffect. For more information on component styling see the HTML5 Viewer SDK User Guide and the default styles section.

Localizable Symbols

VideoPlayer also has s text symbol that you can localize either in a preset or in the viewer page though the mechanisms provided by the ParameterManager. For more information on localization consult the ParameterManager API documentation and HTML5 Viewers SDK User Guide.

Closed Caption Support

The VideoPlayer component supports closed captioning through hosted WebVTT files. Overlapping cues are not supported. Regions are not supported. Supported cue positioning operators

Example Code
This example demonstrates how to use the VideoPlayer component in a simple video viewer. In this example a Container object,
a VideoPlayer object, and a PlayPauseButton object are created. Every time a user clicks the button, the VideoPlayer playback
starts or pauses.

The code below does the following:

The Scene7 HTML5 SDK is linked to the page and the required s7sdk components are included in the document head.
A CSS Style is defined in the document head to control the appearance of the viewer.
The s7sdk.Util.init() method is called to initialize the SDK.
A ParameterManager object is created to handle component modifiers for the viewer.
An initViewer() function is defined. This function initializes several modifiers (hard coded for example purposes),
then creates the component objects required for this simple example. The initViewer() function also adds event listeners
that designate functions to handle relevant component events (which might be dispatched by the components as a result of
user interactions, changes in a component's state, etc.).
Handler functions are defined to respond to the component event listeners added in the initViewer() function.
An event listener is added to the ParameterManager object that designates the initViewer() function as the handler
to call when the Scene7 SDK is loaded and ready.
Finally, the init() method is called on the ParameterManager object to start the viewer.
