getVideoRepresentation

Description

Get information about the video Representation currently loaded.

Note that this only returns the video Representation that is loaded which may be different to the one that is played.

The returned value can either be an object or:

  • null if no video track is enabled right now.
  • undefined if no video content has been loaded yet or if its information is unknown.

In case it a video track is set and its properties is known, the getVideoRepresentation method will return an object with the following properties:

  • id (string): The id used to identify this Representation. No other video Representation for the same Period will have the same id.

    This can be useful when locking the Representation through the lockVideoRepresentations method.

  • bitrate (Number|undefined): The bitrate of this Representation, in bits per seconds.

    undefined if unknown.

  • width (Number|undefined): The width of this video Representation, in pixels.

  • height (Number|undefined): The height of this video Representation, in pixels.

  • codec (string|undefined): The video codec the Representation is in, as announced in the corresponding Manifest.

  • frameRate (number|undefined): The video frame rate, in frames per second.

  • hdrInfo (Object|undefined) Information about the hdr characteristics of the Representation. (see HDR support documentation)

You can also get the information on the loaded video Representation for another Period by calling getVideoRepresentation with the corresponding Period’s id in argument. Such id can be obtained through the getAvailablePeriods method, the newAvailablePeriods event or the periodChange event.

// example: getting Representation information for the first Period
const periods = rxPlayer.getAvailablePeriods();
console.log(rxPlayer.getVideoRepresentation(periods[0].id);
In DirectFile mode (see loadVideo options), this method returns "undefined".

Syntax

// Get information about the currently-loaded video Representation
const videoRepresentation = player.getVideoRepresentation();

// Get information about the loaded video Representation for a specific Period
const videoRepresentation = player.getVideoRepresentation(periodId);

  • arguments:

    1. periodId string|undefined: The id of the Period for which you want to get information about its currently loaded video Representation. If not defined, the information associated to the currently-playing Period will be returned.

  • return value Object|null|undefined
