What Does Media Changing Mean In Media Player __FULL__

MediaPlayer provides the pause(), play(), stop() and seek() controls as well as the rate and autoPlay properties which apply to all types of media. It also provides the balance, mute, and volume properties which control audio playback characteristics. Further control over audio quality may be attained via the AudioEqualizer associated with the player. Frequency descriptors of audio playback may be observed by registering an AudioSpectrumListener. Information about playback position, rate, and buffering may be obtained from the currentTime, currentRate, and bufferProgressTime properties, respectively. Media marker notifications are received by an event handler registered as the onMarker property.
The operation of a MediaPlayer is inherently asynchronous. A player is not prepared to respond to commands quasi-immediately until its status has transitioned to MediaPlayer.Status.READY, which in effect generally occurs when media pre-roll completes. Some requests made of a player prior to its status being READY will however take effect when that status is entered. These include invoking play() without an intervening invocation of pause() or stop() before the READY transition, as well as setting any of the autoPlay, balance, mute, rate, startTime, stopTime, and volume properties.
The same MediaPlayer object may be shared among multiple MediaViews. This will not affect the player itself. In particular, the property settings of the view will not have any effect on media playback.
A main tenet of SIMID is the separation of the interactive layer from the mediaasset. This clear separation allows publisher players to be in control of theirstreams and enables use cases such as server-side ad insertion (SSAI), as wellas live streaming.
SIMID was built with strong security from the ground up, and is designed to besandboxed from the media player, providing peace of mind to publishers whenserving ads from third party services. SIMID aims to provide the tools andcontrols to allow creatives to offer rich augmented user experiences whiledegrading gracefully if certain features are not supported.
Nonlinear ads implement two states: collapsed and expanded. The player renders the nonlinear ad in the original state, collapsed, while media content progresses uninterrupted. The expanded ad state typically occupies the entire player viewport and requires the media content to be paused. The expanded state of the nonlinear ad usually occurs via user interaction with the creative.
SIMID borrows media-related semantics and naming conventions from the standard HTMLMediaElement behavior. In player implementations where an HTMLMediaElement is not used, the player must translate events and property values into the associated SIMID:Media message.
The player must not queue messages in cases where the creative iframe initialization happens in the middle of the ad media playback. The player posts only messages that communicate events that occur after the iframe initialization.
When the duration of the media changes due to the player receiving the media resource metadata (in HTML, HTMLMediaElement dispatches the durationchange event), the player posts a SIMID:Media:durationchange message.
The player may resize the ad to its default dimensions without the creative requesting a collapse. The player may collapse the ad based on its internal logic or in response to the user resuming media playback.
The message, clickThru, is not an explicit media-pausing directive to the player. If the environment permits, the player must pause ad media in all cases when the user navigates away from the player-hosting page or app, including clickthrough. See Page Visibility API.
Under normal circumstances, the player pauses the media. In cases when the content is video, the player resizes the creative iframe to the dimensions of the video and places the expanded creative at video zero coordinates.
In the case where publisher environments prohibit media playback interruptions, waiting for the creatives is not possible. The media player renders the ad media immediately - before the creative confirms its readiness (Special Creative Initialization Cases, 1). Some examples include SSAI and live broadcasts.
The creative may respond with a reject based on its internal logic. In response to reject, the player proceeds with the ad media playback. The player may unload the iframe. The player reports VAST error trackers with the errorCode specified by the creative.
If the variableDurationAllowed flag is set to true thenthe player should enable media pause by the SIMID creative via theSIMID:Creative:requestPause message. The player must respond toSIMID:Creative:requestPause with the AdPaused event.
When the SIMID creative would like to resume media playback, it should send aSIMID:Creative:requestPlay message. The player mustrespond to SIMID:Creative:requestPlay message with resolve and play the media.
This scenario applies when the creative signal to the player to dismiss the ad, typically at the prompting of the user. A good example is a survey that allows the viewer to skip immediately to content when completed.
This specification does not define the user experience for a close control (close button) or other generic media interaction behavior by the ad creative or the media player. The publisher media player is in full control over its user experience and can present its controls (or hide them) as needed. The publisher media player may dismiss the ad creative at any point in time. Some implementations may have a publisher provided close control, as well as various other controls, and others may not.
The media player may manage several ads that are in different phases of their lifespans; multiple concurrent sessions may be active. For example, while the player is rendering ad-A, it preloads and engages ad-B. Simultaneous two-way communication between the player and both ads persists.
Typically, the player should wait for the creative to post a createSession message before proceeding to the simultaneous rendering of both ad media and the interactive component. However, SIMID recognizes scenarios when:
If the creative has not established a session before the media playback is complete, the player will report a VAST Error tracker with the proper error code. Examples of situations when this may occur are listed below.
Windows Media Player 10 or later is designed to synchronize digital media content to devices using a playlist synchronization model. This means that content intended to be copied to a device must be part of a playlist. When the user chooses to transfer individual digital media content from his or her computer to a device, Windows Media Player adds the content to a default playlist for copying.
Because portable devices have a limited storage capacity, it is possible for the user to choose to synchronize more digital media content than the device can store. Windows Media Player synchronizes content in priority order. The user can define the priority order by using a dialog box that can be accessed from the Devices feature. In response to user input to your program, you can change the priority order programmatically by changing the values of certain playlist attributes. Collectively, these attributes are called the Sync attributes.

When comparing CBR and VBR encoding for a given media file, you can make the following generalizations: A CBR file can play back more reliably over a wider range of systems because a fixed data rate is less demanding on media players and computer processors. However, a VBR file tends to have a higher image quality because VBR tailors the amount of compression to the image content.
Google Cast sender applications control the playback on the receiver device by sending messages in JSON format to the receiver application. Likewise, the receiver sends messages back to the sender, also in JSON. The messages may be commands from the sender that change the player state, responses to those commands from the receiver, or data structures that describe the media for the receiver application.
The height and width are optional on only one item in an array of Images. For example, if there is a single item returned, then they are optional; if there are two items returned, one item must specify a height and width, but the sender may choose to go with the \"default\" option if it does not like the one passed with specific parameters. Name Type Description url URI URI for the image height integer optional Height of the image width integer optional Width of the image VolumeThe media stream volume. Used for fade-in/fade-out effects on the media stream. (Note: systemvolume is changed using the sender APIs.) Stream volume must not be used in conjunction withthe volume slider or volume buttons to control the device volume. At least one of the followingparams must be passed to change the stream volume.
Combinations are described as summations; for example, Pause+Seek+StreamVolume+Mute == 15. volume Volume Stream volume customData object optional Application-specific blob of data defined by the receiver application Commands from sender to receiverThese commands control the media player. All customData objects in the messages below must be optional (i.e. the receiver should degrade properly if data is not passed). This will allow generic remote control apps to work properly.
optional (default is true) If the autoplay parameter is specified, the media player will begin playing the content when it is loaded. Even if autoplay is not specified, media player implementation may choose to begin playback immediately. If playback is started, the player state in the response should be set to BUFFERING, otherwise it should be set to PAUSED currentTime double optional Seconds since beginning of content.
