• Docs are now published to twilio-cdn, please update your bookmarks
  • 7.9.0
  • latest
  • ktx
  • noise cancellation

• Get real-time transcriptions using the new receiveTranscriptions(...) option in the ConnectOptions class. Retrieve the set value using the getter isReceiveTranscriptionsEnabled.

1
ConnectOptions connectOptions = new ConnectOptions.Builder(accessToken)
2
        .receiveTranscriptions(true)
3
        .build();
4

5
Video.connect(context, connectOptions, roomListener);

• When transcriptions are available, your app receives them using a new optional method in the Room.listener interface, onTranscription(@NonNull Room room, @NonNull JSONObject json). The payload in this callback will contain a JSONObject object with the transcription data. An example of this object:

1
{
2
    "language_code" = "en-US";
3
    "partial_results" = 0;
4
    participant = PA00000000000000000000000000000000;
5
    "sequence_number" = 2;
6
    timestamp = "2025-06-23T17:51:47.710028073Z";
7
    track = MT00000000000000000000000000000000;
8
    transcription = "This is a test.";
9
    type = "extension_transcriptions";

}

Video sizing issues can occur in two circumstances:

• Someone publishes a video in landscape mode. The simulcast layers are set for landscape mode. The viewer's device isn't held in landscape mode, so the simulcast layers may not display correctly. This remains true if both devices aren't oriented in portrait mode.
• Someone publishes a video at 720p with VP8 simulcast turned on. The subscriber varies their hints between 180p, 360p, and 720p. This may result in the subscriber receiving larger than expected video.

• This release introduces Adaptive Simulcast along with new Video Encoding modes for publishers. Adaptive Simulcast reduces publisher resource usage by only sending those encodings for a video track that are needed by subscribers or by the media server (when recording is enabled). This is an opt-in feature and can be enabled by setting the new Connect Option videoEncodingMode to AUTO, which allows the SDK to select video codecs, use adaptive simulcast, and manage encodings automatically. When videoEncodingMode Connect Option is set to AUTO, the preferVideoCodecs and/or EncodingParameters.maxVideoBitrate Connect Options cannot be set.

• Added a new videoEncodingMode field to ConnectOptions.
• The videoEncodingMode API is mutually exclusive with existing codec management APIs EncodingParameters.maxVideoBitrate and preferVideoCodecs.

• Video Content Preferences might prefer larger video than needed when device orientations are mismatched. For example, if a participant in landscape mode publishes video, then the subscribing participant must also be in landscape mode in order for the correctly sized simulcast layers to be selected. The same is true for the portrait orientation.

• Added ability to configure enabling/disabling support for video codec hardware encoders via global configuration and a properties file. The hardware encoder settings are loaded from a properties file located in the assets directory of the application. If the file does not exist, default settings are used. By default the filename is twilio-video-config.properties, the filename can be overridden by setting the system property com.twilio.video.Video.configPath.

The properties file currently supports the following settings:

• Fixed a bug that would cause a crash if a hardware encoder throws an exception when constructed. [VIDEO-8948]
• Fixed a bug that could cause a crash when tracks are repeatedly publish/unpublished. [VIDEO-8649]

• Added VP8 simulcast support using the software encoder. When simulcast is enabled, the software VP8 encoder will be used, even on devices with VP8 hardware encoding support.

• Fixed a bug which could occur when connected to a Peer-to-Peer or Go Room and publishing a second video track before another Participant joins, causing the connection to be terminated or the second video track not to be fully established.
• Fixed a bug which could cause the Room connection to be terminated by the server.
• Fixed a bug which could cause the media connection not to be re-established after network changes.

• Added error code definition PARTICIPANT_SESSION_LENGTH_EXCEEDED_EXCEPTION.

• Fixed a bug where if an exception occurs when connecting to a Room, the Room instance could leak and setting a custom audio device could fail.
• Fixed a bug where media could incorrectly be detected as not flowing after the network connectivity changes.

• As of 6.0.0 of the SDK, hardware video encoding doesn't publish all of the three simulcast layers when VP8 simulcast is enabled on Android. This affects Video Content Preferences from working properly for subscribing video participants since the feature requires all three simulcast layers to switch between. Our team is working on a fix for this, but the feature does work when VP8 simulcast is used to publish video from participants using the JavaScript or iOS SDKs.

• The SDK has been upgraded to use Chromium WebRTC 88.
• The SDK uses Unified Plan SDP semantics instead of Plan-B. This brings several important benefits:
  • Improved interoperability with Firefox, Safari and Chrome in Peer-to-Peer and Go Rooms.
  • Track level operations like publishing and unpublishing are more reliable.
• Improved performance of Room.getStats() by adopting the W3C standardized RTC stats API.
• Unused codecs for a track are removed from the local SDP offer in order to reduce the SDP size, once codecs for the track have been negotiated.

• The minimum Android SDK version has been increased from 16 to 21. Please visit our migration guide for more details on how to update your application to 7.0!
• The ordering of RemoteParticipantObserver.onAudioTrackSubscribed() and RemoteParticipantObserver.onVideoTrackSubscribed() is not strictly guaranteed. In this release the ordering of these callbacks may be different when compared to previous releases.
• The value of LocalVideoTrackStats.frames_encoded now reflects the total number of frames encoded for a simulcast track.

• Fixed a bug causing the Connect Option enableIceGatheringOnAnyAddressPorts not to have any effect.
