To play streams protected with Adobe Access DRM, invoke this API. Alternately, drmauthenticatedata attribute can be specified in the player. See AdobePSDK.videoBehavior for details. New in The following features are new in version 2.4.7: Addition of the UI Configurator in the UI Framework ou can configure the player in one of the following ways: Using a JSON object Using APIs To help generate the JSON object, Browser TVSDK provides a UI Configurator tool. In this tool, you can select various settings, click Test Configuration to verify the settings, and click Download Configuration to download the settings. After downloading the file, you can pass the contents of this file as JSON object, to the ptp.videoplayer API. Addition of the MediaPlayerItemConfig API to the UI Framework

5 5 Various features, including advertisingmetadata, advertisingfactory, adsignalingmode, networkconfiguration, customrangemetadata, usehardwaredecoder, subscribetags, adtags, thumbnailscrubber, billingmetricsconfiguration, can be configured through MediaPlayerItemConfig. For more information, see the AdobePSDK.MediaPlayerItemConfig documentation in the Browser TVSDK API documentation. In the UI Framework, the way of passing network configurations through the player configuration has been modified. Version var player = ptp.videoplayer( #videoholder, { player: { networkconfiguration: <network configuration object> } }; Version var player = ptp.videoplayer( #videoholder, { player: { mediaplayeritemconfig: { networkconfiguration: <network configuration object> }; } } Support for DRM and Analytics workflows in the UI Framework DRM configurations and Analytics Tracking can be enabled through the UI Framework. Addition of AdobePSDK.embedSWFinFullScreenDiv API This new API provides flexibility to the player app for selecting the div in which it can embed the Fallback.swf file. Replaced getversion API from AdobePSDK.MediaPlayer class with AdobePSDK.Version class for TVSDK version related information. For details, see AdobePSDK.Version API here. New in The following features are new in version 2.4.6: Browserify Support Browserify allows you to use the node.js style modules in the browser. ou can define the dependencies and Browserify bundles everything into one JavaScript file.

Important: The deprecated enum MediaPlayer.Events and deprecated constants in Enum PSDKErrorCode have been removed in version For more information, see Converting from Browser TVSDK to version New in The following features are new in version 2.4.5: Full Event Replays and Ads

6 6 HLS Full Event Replay (FER) streams now supports ad resolution and ad behaviors. To enable this support, set the ad signaling mode to MANIFEST_CUES when creating the MediaPlayerItemConfig object. MediaplayerView ScalePolicy Support Application developers can now specify a different scalepolicy for the view using MediaplayerView scalepolicy property. Anamorphic Content Support Anamorphic content playback is now supported when using MSE and playback. Selective application of withcredentials When withcredentials is set to true, the Access-Control-Allow-Origin header cannot be set to a wild card. Depending on the response of server, Browser TVSDK will selectively set the withcredentials attribute. For more information about this support, see Browser TVSDK API docs. Version The following features were new in version 2.4.4: sample app This release provides support for a sender and receiver app that demonstrates playback of DASH streams and DASH Widevine streams with client side ad insertion. Advanced failover support This release contains support for advanced failover use cases (segment and server failover) for HLS streams. Version The following features were new in version 2.4.3: Custom tags for DASH Inline custom tags (Events) can be subscribed to and received as TimedMetadata object. of streams without extensions HLS and DASH streams without extensions are now supported. For the manifest file, the resourcetype needs to be specified when loading the resource. For segments and VTT files, the Content-Type response header is used to determine the content type. Version The following features were new in version 2.4.2: API Parity For a complete list of the API parity, see the TVSDK for 1.4 DHLS to Browser TVSDK 2.4 Migration Guide. Sample-AES support This release adds support for Sample-AES encrypted content playback on MSE and fallback. The requirement to host AES content over secure origin on Google Chrome have been removed.

7 7 Tip: AC3 and enhanced AC3 codecs are not yet supported. Tokenized stream playback HLS streams that are delivered through a Content Delivery Network (CDN) can sometimes use authentication tokens on the manifest and segment requests for verification, and these tokens can be provided as URL parameters or as cookie headers. The playback of such streams are now supported. Version The following features were new in version 2.4.1: UI framework This framework, designed to accelerate UI development for JavaScript-based video player applications, consists of APIs for including basic controls like play/pause and volume and for easily adding or removing elements like scrub bar states and closed caption settings.ou can specify the behavior associated with controls, create custom controls, and skin the player UI. This all happens through the framework, with no need for manipulating the DOM structure directly. HLS playback enhancements for Live streams This release supports discontinuities caused by ad insertion. It uses the EXT-PROGRAM-DATE-TIME tag followed by the EXT-MEDIA-SEQUENCE tag to synchronize across adaptive bitrate profiles for smooth playback. VPAID 2.0 support The video player ad-serving interface definition (VPAID), version 2.0, provides a rich media experience for users and allows publishers to better target ads, track ad impressions, and monetize video content. This release supports linear JavaScript VPAID ads for video-on-demand () content. Custom HLS tags Media streams can carry additional metadata in the form of tags in the playlist/manifest file.

Issues fixed in version The following issues are fixed in Browser TVSDK verison : Core playback features: 19192: TVSDK now implements TextFormat:bottomInset and TextFormat:safeArea. Due to these enhancements, closed captions can be re-positioned if the control bar is displayed on the screen : Closed captions persist on the screen in case of seek across discontinuity till new captions appear : Seek back is rejected due to a race condition during segment append : Making seekable playback ranges available when the player is in INITIALIZED state. Due to these changes, start session at position is now supported : 608/708 closed captions are going out of sync after ad insertion for DASH streams. Ad insertion features: 21179: Mid-roll related issues (long pauses, black frames) with content are now resolved by correctly setting the ad.primaryasset.adparameters property : The MP4 file with highest bit rate is selected for transcoding if MP4 is not a valid mime-type and the creative repackaging feature is enabled : TVSDK now passes ad system and creative ID from the VAST response as query parameters in the creative packaging request in order to support additional normalization rules. Issues fixed in version The following issues are fixed in Browser TVSDK verison : Core playback features: 21060: Invalid codec error thrown with HLS streams that contain discontinuity and the ISO BMFF boxes run to end of stream : Auto play not working on ios after the first video playback in a playlist is completed : Frame rate is returned as NaN by the QoS provider on Chrome browser : Unsupported codec error thrown on encountering segments with no data : SDK now starts with the current bit rate on seek instead of switching immediately based on ABR policy : When in portrait mode on IE11 (Windows 8.1), the video screen becomes small. Content protection feature:

18 : Skip segments that fail decryption in case of HLS AES-128 streams. Issues fixed in version The following issues are fixed in Browser TVSDK verison 2.4.9: Core playback features: 13407: DASH streams may stall if Firefox stops sending "ontimeupdate" event during playback : During Muxed Audio Video Content of segments having non-matching start times via MSE, Audio Sync Error between Representations accumulates on ABR switches, ultimately resulting in Error (Chromium issue #663686) : On playing particular ISO-BMFF stream on Firefox browser, playback gets stuck(firefox issue# ). This is fixed since Firefox v : Uncaught (in promise) ReferenceError: width is not define , 19299: Video flicker issue at segment boundary. This was happening since SDK was not calculating the last sample's Composition time offset correctly : does not starts for HLS content and HLS Ad on Firefox v53 (Firefox issue #354653) : Program Date Time is received as key instead of value when received as timed metadata object : usedefaultresizehandler throws an error with fallback : Fallback not working with Player v : Firefox stops buffering data for certain HLS streams leading to stall : Player throws media decode error on Chrome due to incorrect handling of video samples with zero duration : stalls on browser error 'QuotaExceeded' : In HLS Live stream 608 CC text sometime appear as misspelled : ClosedCaptions size parameter doesn't change font size : Closed captions boxes overlap with each other making them illegible. Core (CSAI) features: 20043: Missing Ad impression and Ad tracking calls with multiple ads and third party redirects : When using creative repackaging, all ads in the ad break need to be repackaged successfully otherwise the ad break is completely discarded : Ad playback is skipped and main content resumes immediately rather than wait for timeout of 20 seconds if ad manifest is not available. Issues fixed in version Update (Build 6002) The following issues are fixed in Browser TVSDK verison Update (Build 6002): 14126: may stall on Firefox (issue # ) due to internal gap in MSE source buffer. Try seeking in order to resume playback 19608: Fix to honor the timeoffset value from Auditude VMAP response : Fixes Video Stall in Internet Explorer 11 on Windows : Fixes for ABR issues with HLS : Fixes the Ad playback with HLS content that was broken in Mozilla Firefox v and 19744: The issues fixes the inconsistency in selecting bitrate after a seek operation. Now the bitrate selection on seek is the lower value of the current bitrate and the bitrate at the start-up.

19 : stuck and buffering overlay appears for infinite time after seeking is performed for 3-4 times : Confirm compliance with Chrome 59 Beta Verified Media Path (VMP) requirements. btvsdk was able to playback Widevine DRM content with Chrome 59 Beta : DRM playback on UI-Framework was broken. Now, it invokes acquirelicense even if there is no policy in the metadata. Issues fixed in version The following issues are fixed in Browser TVSDK release: 10075: When seeking ahead of timeline, play complete event was not received on Firefox and Chrome and seek event was not received on Firefox : Play complete event not received on Windows 8.1 Internet Explorer : For SSAI streams, playback is supported. Tracking of stitched ad is not supported : At times rewind causes the video player to remain in buffering state forever : Ad markers are not available through UI framework : Ads only playback not works through UI framework : AES-128 key is requested once for a playlist and subsequent requests are served from the cache.

SDK now considers the cue markers and does not rely on time offset values in VMAP responses : Ads only playback leads to script error at end of ad : CRS playlist requests were failing with 404 error. The 1401 and 1403 requests from Browser TVSDK are now updated to take care of that : acquirelicense used to be called before setauthenticationtoken because of which a valid license was returned irrespective of the token validity. This is fixed now and acquirelicense is called only after setauthenticationtoken response. Issues fixed in version The following issues were fixed in version 2.4.7: 8397: HLS Live streams generated through Adobe Media Server might not play if the segments do not start with a Key frame : Multiple Seek related issues fixed for HLS stream on Chrome browser : On Chrome browser, if seek or pause is triggered immediately after play(), playback may stop with error DOMException: The play() request was interrupted by a call...(chromium issue# ) : MediaPlayer Params such as volume, abrcontrolparameters, and ccstyle are not set to Defaults on Resetting the Player.
