    Known Issues

    This topic lists known issues for Brightcove Beacon.

    Generated apps

    General

    • Client-Side Ad Insertion (CSAI) is NOT supported.
    • DVR functionality is NOT supported.

    Stream limitations and rapid switching between videos

    1. If a viewer switches quickly between videos it is possible the error shown here may be displayed:
      stream-limitations

      This occurs because it takes a number of seconds for the stream to be released, and if the viewer tries to watch another video before the stream is released, a stream limitation occurs and the error is displayed.

    Parental controls

    1. All content is displayed to end users (in lists, carousels, etc), but when trying to play the video the parental pin will be requested.
    2. Multiple age classifications are NOT supported.

    Mobile web

    1. Mobile web has limited support. On devices with a width under 365px a message is displayed to install the appropriate native Brightcove Beacon app.

    Native SDK offline playback

    General

    Advertising

    Neither client-side nor server-side advertising is supported with offline playback.

    HLSe

    HLSe content is not supported with offline playback using the Brightcove Native SDK for Android, iOS or tvOS.

    Low power mode

    Low power mode on devices may affect certain features, including downloading. For more information, see the following:

    Shared videos

    Shared videos can be downloaded for offline viewing only if the original video can be. The property is inherited from the original video and cannot be changed for shared video only.

    Audio-only

    The Native SDKs support audio-only content with Offline Playback. You control what viewers see, whether it is a poster image or a custom screen.

    The Native SDK for Android requires a VideoView, and the Native SDK for iOS requires a UIView. Because of this, background audio is not supported. This means that audio will not keep playing when a user sends the app to the background.

    Android: App deletion

    When the app is deleted, all downloaded content is removed. This is true as long as the default storage location is not overridden.

    iOS: AirPlay

    As a security feature, you cannot stream an offline HLS video to an AirPlay device for playback. This is confirmed by Apple to be an AVFoundation limitation.

    Native SDK for iOS

    • With iOS 12, setting the kBCOVOfflineVideoManagerDisplayNameKey field value with multibyte characters may cause a download error. This is because multibyte characters are encoded as longer string values, and iOS restricts the string length to 255bytes. This problem has been reported to Apple.
    • With iOS 12, the didProgress event may stop firing when your app is resumed from background to foreground while downloading. You will notice that the downloading status is no longer updated. This problem has been reported to Apple.
    • When playback is attempted for the same offline video two times in a row, the user may experience unexpected network activity. The AVPlayer may switch to playing the online version of the video. A bug report has been submitted to Apple. For work-around steps, see the Playing the Same Offline Video Twice section of the reference document.
    • If your app is targeting iOS 11.0 - 11.2, we don't recommend concurrent downloads because pause and resume behavior is unreliable with multiple simultaneous downloads. The problem has been fixed with iOS 11.3.

    Native SDK for Android

    • To add support for downloading when the device is locked, either by going to sleep or with the power button, add the following permission to your AndroidManifest.xml file :
      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    • With Android 8.0 and above, it is possible to manage power settings when the app is moved to the background. This can cause the downloading process to stop if the device is disconnected from a power source. In most cases, when the app is brought back to the foreground, the download will continue. It is important to note that power management can be OS and vendor specific. Therefore, the Brightcove Native SDK for Android will not attempt to manage or override settings related to power management.
    • When using Widevine Modular with Android 8.0.0 (and 8.1.0 on some devices), you may notice that a rental license is already expired when you acquire it. This is a known issue with the Widevine Modular CDM, and can not be addressed in either the Brightcove Android SDK or ExoPlayer. Although this issue is not reproducible for most devices using Android 8.1.0, there is no workaround for those devices using Android 8.0.0 or 8.1.0, where it does occur.
    • Observed only with Android 5.x devices: When releasing the Widevine license by calling the OfflineLicenseManager.releaseLicense method, a MediaDrmStateException error is thrown.
    • In the OfflinePlaybackSampleApp, there are two Widevine license expiration periods.

      • absoluteExpiration is an expiration date of the license to start playback of downloaded video
      • playDuration is how long the video can be played

      When playDuration becomes less than 60 seconds, the Widevine CDM handles the license as expired and throws a Failed to get key request error. Playback will not start with this Widevine license exception.

      With the Brightcove Native SDK for Android v6.1.0+, you can try calling AbstractOfflineCatalog.requestRentalLicense(Video, Date, long, EventListener) or AbstractOfflineCatalog.requestPurchaseLicense(Video, EventListener) to retrieve a new license. Note: The device must be online to acquire a new license.

    Live events

    Beacon does not track concurrent users for live events

    Beacon currently has a limitation where Beacon players do not fully support Live Analytics (CCU). The following analytics metrics are not currently tracked by Beacon:

    • video_impression - video loaded into a player
    • video_engagement - concurrent views over the video duration
    • alive_ss_ad_Start - ad starts for Live events
