Transmit data about video status

To improve video quality in searches, we need information about video status. For example, the time when the video started, stopped, or was rewound. It's also important to pass on information about errors that occurred while the video was playing.

  1. Events that relate to video status
  2. Error notifications
  3. Support parameters in player URL
  4. Manage your player on Smart TV devices

Events that relate to video status

To pass on data about a video's status, use the postMessage function for each event that occurs in the player (for example, when the video starts playing). Call the window.parent.postMessage function in JavaScript. Pass the name of the event along with the event parameters (for example, the progress bar position) as arguments.

Note. Please note that the postMessage function must be called for the parent object — window.parent. This is because the video is placed in a separate frame (in the iframe element) rather than on the main Yandex search results page.
window.parent.postMessage({
    event: <Event name>,
    // additional event parameters
}, ' *');

To display the player in the video search app for TV and in the mobile video search, you need to pass the mandatory events and their parameters. Transmitting additional events makes it easier for users to interact with the player.

Below is an example of data that's transferred when a video starts. When a user clicks on the Play button on the player, the window.parent.postMessage function is called along with the necessary parameters.

// Sends message when the video starts playing
window.parent.postMessage({
  event: 'started',
  duration: 30,
  time: 5 // If the video continues playing starting at 5 seconds
}, ' *');

Error notifications

The player must pass the following error codes to the window.parent.postMessage function so that we find out about any problems that occur:

Error code Description

101 Video deleted.
102 The videoclip or account has been blocked.
103 The video doesn't exist or the URL isn't supported.
