CHANGELOG.md

v4.0.0 (2024-02-21)

Changes

• Create "FREEZING" player state for cases where the playback position is currently not advancing due to an unknown reason, to separate it from regular "BUFFERING". [#1146]
• The RELOADING player state (gettable through the getPlayerState and playerStateChange API) can now happen at any time to unlock playback.
• Remove bitrate API: getAvailableVideoBitrates, getAvailableAudioBitrates, setAudioBitrate, setVideoBitrate, getAudioBitrate, getVideoBitrate in profit of the Representations lock APIs [#1144]
• Remove max bitrate API: setMaxVideoBitrate, setMaxAudioBitrate, getMaxVideoBitrate and getMaxAudioBitrate methods as well as the maxVideoBitrate and maxAudioBitrate options in profit of the Representations lock APIs
• Remove min bitrate API: setMinVideoBitrate, setMinAudioBitrate, getMinVideoBitrate and getMinAudioBitrate methods as well as the minVideoBitrate and minAudioBitrate options in profit of the Representations lock APIs
• Remove track preferences API (methods: getPreferredAudioTracks, getPreferredVideoTracks, setPreferredAudioTracks and setPreferredVideoTracks, types: IAudioTrackPreference, ITextTrackPreference and IVideoTrackPreference) in profit of the new tracks API
• Remove getManualVideoBitrate and getManualAudioBitrate in profit of the new Representations lock APIs
• Replace initialAudioBitrate and initialVideoBitrate constructor options with a single baseBandwidth option, which better translates what this option is actually doing and allows for future optimizations on our side. [#1155]
• Rename audioTrackSwitchingMode loadVideo option into defaultAudioTrackSwitchingMode [#1030]
• Remove manualBitrateSwitchingMode loadVideo option to instead rely on the switchingMode property of each lockVideoRepresentations and lockAudioRepresentations calls. [#1030]
• Remove audioBitrateChange and videoBitrateChange events in profit of the new audioRepresentationChange and videoRepresentationChange events
• Remove availableAudioBitratesChange and availableVideoBitratesChange events. Those are less needed with the new Representations lock API and can be mostly replicated through the audioTrackChange and videoTrackChange events
• "Flatten" the transportOptions loadVideo options by putting all its inner properties directly at the top level of loadVideo options, to simplify its documentation and discoverability [#1149]
• Remove limitVideoWidth constructor option in profit of the more configurable videoResolutionLimit constructor option
• Rename networkConfig into requestConfig and re-organize its inner properties to pave the way for future request-related APIs.
• Remove stopAtEnd loadVideo option and don't automatically stop when reaching the end by default. This behavior can be counter-intuitive and can be very easily implemented by the application.
• Remove decipherabilityUpdate event as it appeared to be not easily exploitable and exposed internal logic too much [#1168]
• Remove getUrl method in profit of the more powerful getContentUrls
• Impossibility to play the content due to unsupported audio and/or video tracks now triggers an error with the MANIFEST_INCOMPATIBLE_CODECS_ERROR instead of MANIFEST_PARSE_ERROR
• Remove methods: getManifest, getCurrentAdaptations and getCurrentRepresentations, as they reveal the RxPlayer's internals too much
• The "smooth" transport now needs to be communicated the URL of the Manifest directly (previously, it was possible to redirect it to a XML or JSON file first due to Canal+ legacy reasons).
• Remove the supplementaryTextTracks loadVideo option. You can use the TextTrackRenderer tool if you wish to diplay external subtitles on top of your content.
• Rename maximumBufferTime in positionUpdate events to maximumPosition
• Remove getVideoPlayedTime and getVideoLoadedTime methods. Their names was very confusing and can be re-implemented relatively easily using the media element's buffered property.
• Rename getVideoDuration to getMediaDuration, to avoid confusion with the video track's duration.
• Rename getVideoBufferGap to getCurrentBufferGap, to avoid confusion with the "buffer gap" specific to the video track.
• Remove image-related API: supplementaryImageTracks loadVideo option, imageTrackUpdate event, getImageTrackData method. Those are better handled by an application. The parseBifThumbnails tool is still available.
• Replace keySystems[].licenseStorage keySystems option (for a loadVideo call) by the better-named persistentLicenseConfig. The persistentLicense boolean (also a keySystems option) has also been removed because it was redundant with it) [#1147]
• Remove persistentStateRequired API, in profit of the more powerful persistentState API [#1148]
• Remove distinctiveIdentifierRequired API, in profit of the more powerful distinctiveIdentifier API [#1148]
• Remove keySystems[].fallbackOn loadVideo property as it's now replaced by the more powerful keySystems[].onKeyOutputRestricted and keySystems[].onKeyInternalError properties.
• Remove keySystems[].onKeyStatusesChange API as it seems to never be used [#1148]
• Remove keySystems[].throwOnLicenseExpiration API as it can now be fully replaced by the keySystems[].onKeyExpiration option
• Remove aggressiveMode from the transportOptions loadVideo option
• Remove deprecated throttleWhenHidden player option in profit of throttleVideoBitrateWhenHidden
• Change payload of periodChange events, so they emit only core properties related to a Period.
• Change arguments given to a transportOptions.segmentLoader function (the loadVideo option): it now doesn't give the full Manifest, Period, Adaptation, Representation and ISegment structures in arguments but only core properties from it [#995]
• Custom manifestLoader function added to what was previously the loadVideo's transportOptions option now set an object as argument (with an urlproperty), to let us bring improvements on it in the future [#995]
• A Representation's frameRate is now always a number - in terms of frame per seconds - instead of a string.
• Update the arguments of the representationFilter API
• Representations (in methods: getAvailableVideoTracks, getVideoTrack, representationFilter, getAvailableAudioTracks, getAudioTrack and events: audioTrackChange and videoTrackChange) can have an undefined bitrate
• Remove deprecated fullscreen related APIs (methods: isFullscreen, setFullscreen, exitFullscreen, event: fullscreenChange) as a a UI is much more adapted to that task and can also bring with it things like a progress bar or HTML text tracks
• Remove deprecated getNativeTextTrack method. If advanced features are wanted, it's better to just use the HTML text track API
• Remove deprecated nativeTextTracksChange event. Same reason than for getNativeTextTrack
• Remove deprecated hideNativeSubtitles from loadVideo options. Same reason than for getNativeTextTrack
• Remove xhr property from a NetworkError. Doing so stop us from using the fetch API
• Remove deprecated defaultAudioTrack and defaultTextTrackin profit of new track APIs
• Remove bitrateEstimationChange event as it is poorly understood (it's not always close to the expected bandwidth) and has a very complex relationship with the chosen quality.
• Remove the notion of environment variables linked to personalized builds (e.g. RXP_DASH) in profit of the minimal RxPlayer.
• Rename IPersistentSessionStorage type to IPersistentLicenseConfig [#1147]
• Remove undocumented audioRobustnesses and videoRobustnesses properties of the keySystems option of loadVideo calls, as more powerful solutions now exist: respectively audioCapabilitiesConfig and videoCapabilitiesConfig [#1148]
• Remove public types ISupplementaryTextTrackOption and ISupplementaryImageTrackOption. Those are the types respectively for supplementaryTextTracks and supplementaryImageTracks which have been removed
• Remove public types IBitrateEstimate as no API depend on it anymore.
• Remove public types IManifest, IPeriod, IAdaptation, IRepresentation, IRepresentationInfos, IBifThumbnail, IBifObject and IExposedSegment as no API depend on them anymore.
• Remove public types IDefaultAudioTrackOption and IDefaultTextTrackOption. Those are the types respectively for defaultAudioTrack and defaultTextTrack loadVideo options which have been removed
• Remove public types IAudioTrackPreference, ITextTrackPreference and IVideoTrackPreference as the corresponding API do not exist anymore.
• Stop officially supporting the Internet Explorer 11 browser
• The MediaError's trackInfo property is now an array renamed as tracksInfo and similar MediaError are grouped in one [#1264]
• The manifestUpdateUrl loadVideo option has been removed as it was unused [#1276]
• volumeChange events are now sending both the audio volume and the muted status [#1348]
• mute/unMute/isMute now rely on the HTMLMediaElement's muted property and not the audio volume [#1348]
• A representationFilter's advertised codec has now been renamed to codecs and is an Array when defined [#1332]
• DASH_WASM and DEBUG_ELEMENT are not experimental features anymore [#1339]
• The parseBifThumbnails function is not an experimental tool anymore [#1339]
• If all Representations from the current track become undecipherable, automatically switch to another track (also send a trackUpdate event) instead of stopping on error [#1234]
• Only send MediaError errors with the NO_PLAYABLE_REPRESENTATION error code when no Representation from all tracks of a given type can be played [#1234]
