Rx-Player API

Table of Contents

Overview

The Rx-player has a complete API allowing you to:

  • load and stop video or audio contents
  • perform trickmodes (play, pause, seek, etc.) as a content is loaded.
  • get multiple informations on the current content and on the player's state.
  • choose a specific audio language or subtitles track
  • set your own bitrate and buffer length
  • and more

The following pages define the entire API.

⚠️ Only variables and methods defined here are considered as part of the API. Any other property or method you might find by using our library can change without notice (not considered as part of the API).

Only use the documented variables and open an issue if you think it's not enough.

Note: As some terms used here might be too foreign or slightly different than the one you're used to, we also wrote a list of terms and definitions used by the RxPlayer here.

Instantiation

Instantiating a new player is straightforward:

import RxPlayer from "rx-player";
const player = new RxPlayer(options);

The options are all... optional. They are all defined in the Player Options page.

Static properties

version

type: Number

The current version of the RxPlayer.

ErrorTypes

type: Object

The different "types" of Error you can get on playback error,

See the Player Error documentation for more informations.

ErrorCodes

type: Object

The different Error "codes" you can get on playback error,

See the Player Error documentation for more informations.

LogLevel

type: string

default: "NONE"

The current level of verbosity for the RxPlayer logs. Those logs all use the console.

From the less verbose to the most:

  • "NONE": no log

  • "ERROR": unexpected errors (via console.error)

  • "WARNING": The previous level + minor problems encountered (via console.warn)

  • "INFO": The previous levels + noteworthy events (via console.info)

  • "DEBUG": The previous levels + normal events of the player (via console.log)

If the value set to this property is different than those, it will be automatically set to "NONE".

Example

import RxPlayer from "rx-player";
RxPlayer.LogLevel = "WARNING";

Tools

MediaCapabilitiesProber

type: Object

An experimental tool to probe browser media capabilities:

  • Decoding capabilities
  • DRM support
  • HDCP support
  • Display capabilities

You can find its documentation here.

Methods

loadVideo

arguments:

  • options (Object)

Loads a new video described in the argument.

The options possible as arguments are all defined in this page.

Example

player.loadVideo({
  url: "http://vm2.dashif.org/livesim-dev/segtimeline_1/testpic_6s/Manifest.mpd",
  transport: "dash",
  autoPlay: true,
});

getVideoElement

return value: HTMLMediaElement

Returns the video element used by the player.

You're not encouraged to use its API, you should always prefer the Player's API.

Example

const videoElement = player.getVideoElement();
videoElement.className = "my-video-element";

getPlayerState

return value: string

The current player's state. Can be either one of those strings:

  • "STOPPED": The player is idle. No content is loading nor is loaded.

  • "LOADING": The player is loading a new content. Most APIs related to the current content are not yet available while the content is loading.

  • "LOADED": The player has loaded the new content, it is now ready to play. From this point onward you can use APIs interacting with the current content such as seekTo or setAudioTrack.

  • "PLAYING": The player is currently playing the content.

  • "PAUSED": The player has paused.

  • "ENDED": The player has reached the end of the current content.

  • "BUFFERING": the player has reached the end of the buffer and is waiting for data to be appended.

  • "SEEKING": The player has reached the end of the buffer because a seek has been performed, new segments are being loaded.

  • "RELOADING": The player needs to reload its current (for example, when switching the current video track). While this state is active, most API related to the currently playing content are not available. This state should be treated like the LOADING state.

As it is a central part of our API and can be difficult concept to understand, we have a special page of documentation on player states.

Example

switch (player.getPlayerState()) {
  case "STOPPED":
    console.log("No content is/will be playing");
    break;
  case "LOADING":
    console.log("A new content is currently loading");
    break;
  case "LOADED":
    console.log("The new content is loaded and ready to be played");
    break;
  case "PLAYING":
    console.log("The content is currently playing");
    break;
  case "PAUSED":
    console.log("The content is currently paused");
    break;
  case "BUFFERING":
    console.log("The content is buffering new data");
    break;
  case "SEEKING":
    console.log("The content is still seeking, waiting for new data");
    break;
  case "ENDED":
    console.log("The content has reached the end.");
    break;
  case "RELOADING":
    console.log("The content is currently reloading");
    break;
  default:
    console.log("This is impossible (issue material!).")
    break;
}

addEventListener

arguments:

  • event (string): The event name.

  • callback (Function): The callback for the event. The same callback may be used again when calling removeEventListener.

Add an event listener to trigger a callback as it happens. The callback will have the event payload as a single argument.

To have the complete list of player events, consult the Player events page.

Example

player.addEventListener("Error", function(err) {
  console.log(`The player crashed: ${err.message}`);
});

removeEventListener

arguments:

  • event (string): The event name.
  • callback (optional) (Function): The callback given when calling the corresponding addEventListener API.

Remove an event listener. That is, stop your registered callback (with addEventListener) to be called as events happen and free up ressources.

The callback given is optional: if not given, every registered callback to that event will be removed. That's why using both arguments is recommended for most usecase.

Example

player.removeEventListener("playerStateChange", listenerCallback);

play

return value: Promise.<void>

Play/resume the current video. Equivalent to a video element's play method.

The returned Promise informs you on the result:

  • if playback succeeds, the Promise is fulfilled

  • if playback fails, the Promise is rejected along with an error message explaining the failure - coming directly from the browser.

    Such failure can for example be due to your browser's policy, which may forbid to call play on a media element without any user interaction. Please note that in that case, you will also receive a warning event containing a MEDIA_ERROR with the code: MEDIA_ERR_PLAY_NOT_ALLOWED.

Note: On browsers which do not support Promises natively (such as Internet Explorer 11), a JavaScript implementation is provided instead. This implementation has the exact same implementation than ES2015 Promises.

Example

const resumeContent = () => {
  player.play();
};

pause

Pause the current video. Equivalent to a video element's pause method.

Note that a content can be paused even if its current state is BUFFERING or SEEKING.

Example

const pauseContent = () => {
  player.pause();
};

stop

Stop playback of the current content if one.

Example

const stopVideo = () => {
  player.stop();
};

getPosition

return value: Number

Returns the video element's current position, in seconds.

The difference with the getWallClockTime method is that for live contents the position is not re-calculated to match a live timestamp.

Example

const pos = player.getPosition();
console.log(`The video element's current position is: ${pos} second(s)`);

getWallClockTime

return value: Number

Returns the wall-clock-time of the current position in seconds.

That is:

  • for live content, get a timestamp in seconds of the current position.
  • for static content, returns the position from beginning, also in seconds.

Use this method to display the current position to the user.

Example

const wallClockTime = player.getWallClockTime();
const nowInSeconds = Date.now() / 1000;
const delta = nowInSeconds - wallClockTime;

if (delta < 5) { // (5 seconds of margin)
  console.log("You're playing live");
} else {
  console.log(`You're playing ${delta} seconds behind the live content`);
}

getVideoDuration

return value: Number

Returns the duration of the current video, directly from the video element.

Example

const pos = player.getPosition();
const dur = player.getVideoDuration();

console.log(`current position: ${pos} / ${dur}`);

getVolume

return value: Number

Current volume of the player, from 0 (no sound) to 1 (maximum sound). 0 if muted (different than videoElement.muted).

Example

const volume = player.getVolume();

if (volume === 1) {
  console.log("You're playing at maximum volume");
} else if (volume === 0) {
  console.log("You're playing at no volume");
} else if (volume > 0.5) {
  console.log("You're playing at a high volume");
} else {
  console.log("You're playing at a low volume");
}

getError

return value: Error|null

Returns the fatal error if it happened. null otherwise.

See the Player Error documentation for more informations.

Example

const error = player.getError();

if (!error) {
  console.log("The player did not crash");
} else if (error.code === "PIPELINE_LOAD_ERROR") {
  console.error("The player crashed due to a failing request");
} else {
  console.error(`The player crashed: ${error.code}`);
}

seekTo

arguments: Object|Number

Seek in the current content.

The argument can be an object with a single Number property, either:

  • relative: seek relatively to the current position

  • position: seek to the given absolute position (equivalent to player.getVideoElement().currentTime = newPosition)

  • wallClockTime: seek to the given wallClock position, as returned by getWallClockTime.

The argument can also just be a Number property, which will have the same effect than the position property (absolute position).

Example

// seeking to 54 seconds from the start of the content
player.seekTo({ position: 54 });

// equivalent to just:
player.seekTo(54);

// seeking 5 seconds after the current position
player.seekTo({ relative: 5 });

// seeking 5 seconds before the current position
player.seekTo({ relative: -5 });

// seeking to live content
player.seekTo({ wallClockTime: Date.now() / 1000 });

isLive

return value: Boolean

Returns true if the content is "live". false otherwise.

Also false if no content is loaded yet.

Example

if (player.isLive()) {
  console.log("We're playing a live content");
}

getUrl

return value: string|undefined

Returns the URL of the downloaded Manifest.

In DirectFile mode (see loadVideo options), returns the URL of the content being played.

Returns undefined if no content is loaded yet.

Example

const url = player.getUrl();
if (url) {
  console.log("We are playing the following content:", url);
}

isFullscreen

⚠️ This method is deprecated, it will disappear in the next major release v4.0.0 (see Deprecated APIs).

return value: Boolean

Returns true if the video element is in fullscreen mode, false otherwise.

Example

if (player.isFullscreen()) {
  console.log("The player is in fullscreen mode");
}

getAvailableVideoBitrates

return value: Array.<Number>

The different bitrates available for the current video Adaptation, in bits per seconds.

In DirectFile mode (see loadVideo options), returns an empty Array.

Example

const videoBitrates = player.getAvailableVideoBitrates();
if (videoBitrates.length) {
  console.log(
    "The current video is available in the following bitrates",
    videoBitrates.join(", ")
  );
}

getAvailableAudioBitrates

return value: Array.<Number>

The different bitrates available for the current audio Adaptation, in bits per seconds.

In DirectFile mode (see loadVideo options), returns an empty Array.

Example

const audioBitrates = player.getAvailableAudioBitrates();
if (audioBitrates.length) {
  console.log(
    "The current audio is available in the following bitrates",
    audioBitrates.join(", ")
  );
}

getVideoBitrate

return value: Number|undefined

Returns the video bitrate of the last downloaded video segment, in bits per seconds.

Returns undefined if no content is loaded.

In DirectFile mode (see loadVideo options), returns undefined.

getAudioBitrate

return value: Number|undefined

Returns the audio bitrate of the last downloaded audio segment, in bits per seconds.

Returns undefined if no content is loaded.

In DirectFile mode (see loadVideo options), returns undefined.

getMaxVideoBitrate

return value: Number|undefined

Returns the maximum set video bitrate to which switching is possible, in bits per seconds.

This only affects adaptive strategies (you can bypass this limit by calling setVideoBitrate), and is set to Infinity when no limit has been set.

getMaxAudioBitrate

return value: Number"undefined

Returns the maximum set audio bitrate to which switching is possible, in bits per seconds.

This only affects adaptive strategies (you can bypass this limit by calling setAudioBitrate), and is set to Infinity when no limit has been set.

setVideoBitrate

arguments: Number

Force the current video track to be of a certain bitrate.

If an video Representation (in the current video Adaptation) is found with the exact same bitrate, this Representation will be set.

If no video Representation is found with the exact same bitrate, either:

  • the video Representation immediately inferior to it will be chosen instead (the closest inferior)

  • if no video Representation has a bitrate lower than that value, the video Representation with the lowest bitrate will be chosen instead.

Set to -1 to deactivate (and thus re-activate adaptive streaming for video tracks).

When active (called with a positive value), adaptive streaming for video tracks will be disabled to stay in the chosen Representation.

You can use getAvailableVideoBitrates to get the list of available bitrates you can set on the current content.

Note that the value set is persistent between loadVideo calls. As such, this method can also be called when no content is playing (the same rules apply for future contents).

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

setAudioBitrate

arguments: Number

Force the current audio track to be of a certain bitrate.

If an audio Representation (in the current audio Adaptation) is found with the exact same bitrate, this Representation will be set.

If no audio Representation is found with the exact same bitrate, either:

  • the audio Representation immediately inferior to it will be chosen instead (the closest inferior)

  • if no audio Representation has a bitrate lower than that value, the audio Representation with the lowest bitrate will be chosen instead.

Set to -1 to deactivate (and thus re-activate adaptive streaming for audio tracks).

When active (called with a positive value), adaptive streaming for audio tracks will be disabled to stay in the chosen Representation.

You can use getAvailableAudioBitrates to get the list of available bitrates you can set on the current content.

Note that the value set is persistent between loadVideo calls. As such, this method can also be called when no content is playing (the same rules apply for future contents).

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

getManualVideoBitrate

arguments: Number

Get the last video bitrate manually set. Either via setVideoBitrate or via the initialVideoBitrate constructor option.

This value can be different than the one returned by getVideoBitrate:

  • getManualVideoBitrate returns the last bitrate set manually by the user
  • getVideoBitrate returns the actual bitrate of the current video track

-1 when no video bitrate is forced.

getManualAudioBitrate

arguments: Number

Get the last audio bitrate manually set. Either via setAudioBitrate or via the initialAudioBitrate constructor option.

This value can be different than the one returned by getAudioBitrate:

  • getManualAudioBitrate returns the last bitrate set manually by the user
  • getAudioBitrate returns the actual bitrate of the current audio track

-1 when no audio bitrate is forced.

setMaxVideoBitrate

arguments: Number

Set the maximum video bitrate reachable through adaptive streaming. The player will never automatically switch to a video Representation with a higher bitrate.

This limit can be removed by setting it to Infinity:

// remove video bitrate limit
player.setMaxVideoBitrate(Infinity);

This only affects adaptive strategies (you can bypass this limit by calling setVideoBitrate).

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

setMaxAudioBitrate

arguments: Number

Set the maximum audio bitrate reachable through adaptive streaming. The player will never automatically switch to a audio Representation with a higher bitrate.

This limit can be removed by setting it to Infinity:

// remove audio bitrate limit
player.setMaxAudioBitrate(Infinity);

This only affects adaptive strategies (you can bypass this limit by calling setAudioBitrate).

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

setWantedBufferAhead

arguments: Number

Set the buffering goal, as a duration ahead of the current position, in seconds. Once this size of buffer reached, the player won't try to download new video segments anymore.

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

getWantedBufferAhead

return value: Number defaults: 30

returns the buffering goal, as a duration ahead of the current position, in seconds.

setMaxBufferBehind

arguments: Number

Set the maximum kept past buffer, in seconds. Everything before that limit (currentPosition - maxBufferBehind) will be automatically garbage collected.

This feature is not necessary as the browser is already supposed to deallocate memory from old segments if/when the memory is scarce.

However on some custom targets, or just to better control the memory imprint of the player, you might want to set this limit. You can set it to Infinity to remove any limit and just let the browser do this job.

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

getMaxBufferBehind

return value: Number defaults: Infinity

Returns the maximum kept past buffer, in seconds.

setMaxBufferAhead

arguments: Number

Set the maximum kept buffer ahead of the current position, in seconds. Everything superior to that limit (currentPosition + maxBufferAhead) will be automatically garbage collected. This feature is not necessary as the browser is already supposed to deallocate memory from old segments if/when the memory is scarce.

However on some custom targets, or just to better control the memory imprint of the player, you might want to set this limit. You can set it to Infinity to remove any limit and just let the browser do this job.

The minimum value between this one and the one returned by getWantedBufferAhead will be considered when downloading new segments.

⚠️ Bear in mind that a too-low configuration there (e.g. inferior to 10) might prevent the browser to play the content at all.

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

getMaxBufferAhead

return value: Number defaults: Infinity

Returns the maximum kept buffer ahead of the current position, in seconds.

setFullscreen

⚠️ This method is deprecated, it will disappear in the next major release v4.0.0 (see Deprecated APIs).

arguments: Boolean

Switch or exit the <video> element to fullscreen mode. The argument is an optional boolean:

  • if set:

    • true: enters fullscreen
    • false: exit fullscreen

  • if not set: enter fullscreen

Note that only the video element will be set to fullscreen mode. You might prefer to implement your own method to include your controls in the final UI.

exitFullscreen

⚠️ This method is deprecated, it will disappear in the next major release v4.0.0 (see Deprecated APIs).

Exit fullscreen mode. Same than setFullscreen(false).

setVolume

arguments: Number

Set the new volume, from 0 (no sound) to 1 (the maximum sound level).

mute

Cut the volume. Basically set the volume to 0 while keeping in memory the previous volume.

unMute

    • getAvailableVideoTracks will return an empty array
    • getTextTrack will return null
    • getAudioTrack will return null
    • setAudioTrack will throw
    • setTextTrack will throw

⚠️ This option will have no effect for contents loaded in DirectFile mode (see loadVideo options).

getManifest

Returns the current loaded Manifest if one. The Manifest object structure is relatively complex and is described in the Manifest Object structure page.

null if the player is either stopped or not loaded.

null in DirectFile mode (see loadVideo options).

The Manifest will be available before the player reaches the "LOADED" state.

getCurrentAdaptations

return value: Object|null

Returns the Adaptations being loaded per type if a Manifest is loaded. The returned object will have at most a key for each type ("video", "audio", "text" and "image") which will each contain an array of Adaptation Objects.

The Adaptation object structure is relatively complex and is described in the Manifest Object structure page.

null if the current Adaptations are not known yet.

null in DirectFile mode (see loadVideo options).

getCurrentRepresentations

return value: Object|null

Returns the Representations being loaded per type if a Manifest is loaded. The returned object will have at most a key for each type ("video", "audio", "text" and "image") which will each contain an array of Representation Objects.

An Representation object structure is relatively complex and is described in the Manifest Object structure page.

null if the current Representations are not known yet.

null in DirectFile mode (see loadVideo options).

dispose

Free the ressources used by the player.

!warning!: The player won't work correctly after calling this method.

getNativeTextTrack

⚠️ This method is deprecated, it will disappear in the next major release v4.0.0 (see Deprecated APIs).

return value: TextTrack|null

Returns the first text track of the video's element, null if none.

This is equivalent to:

const el = player.getVideoElement();
const textTrack = el.textTracks.length ? el.textTracks[0] : null;

getVideoLoadedTime

return value: Number

Returns in seconds the difference between:

  • the start of the current contiguous loaded range.
  • the end of it.

getVideoPlayedTime

return value: Number

Returns in seconds the difference between:

  • the start of the current contiguous loaded range.
  • the current time.

getVideoBufferGap

return value: Number

Returns in seconds the difference between:

  • the current time.
  • the end of the current contiguous loaded range.

getPlaybackRate

return value: Number

Returns the current video normal playback rate (speed when playing). 1 for normal playback, 2 when playing *2, etc.

setPlaybackRate

arguments: Number

Updates the "normal" (when playing) playback rate for the video.

getCurrentKeySystem

return value: string|undefined

Returns the type of keySystem used for DRM-protected contents.

getImageTrackData

return value: Array.<Object>|null

The current image track's data, null if no content is loaded / no image track data is available.

The returned array follows the usual image playlist structure, defined here.

null in DirectFile mode (see loadVideo options).

getMinimumPosition

return value: Number|null

The minimum seekable player position. null if no content is loaded.

This is useful for live contents, where server-side buffer size are often not infinite. This method allows thus to seek at the earliest possible time.

Example

// seeking to the earliest position possible (beginning of the buffer for live
// contents, position '0' for non-live contents).
player.seekTo({
  position: player.getMinimumPosition()
});

getMaximumPosition

return value: Number|null

The maximum seekable player position. null if no content is loaded.

This is useful for live contents, where the buffer end updates continously. This method allows thus to seek directly at the live edge of the content.

Example

// seeking to the end
player.seekTo({
  position: player.getMaximumPosition()
});
