Notable changes


General

  • Updated libWebRTC to 13039 (Chrome 52).
  • Added Recording capability. [Beta]
  • Added new class Info at: sg.com.temasys.skylink.sdk.rtc.Info.java
  • Significant improvement in handling of local camera (see API changes below).


Fixes

  • Skylink Media Relay support is resumed in this version.
  • Fixed issue of not being able to connect to server after multiple rapid consecutive connect/disconnect to room.



Known Issues


With Skylink Media Relay:

 Users with no Audio and no Video for both send and receive configs are not supported:

  1.  If a Peer joins a room with NO_AUDIO_NO_VIDEO for both send and receive configs, the Peer will not be able to connect to other Peer
  2. This issue does not exist in a normal room (without Skylink Media Relay).
  3. Possible workaround is for user to join room with AUDIO_ONLY or VIDEO_ONLY for setAudioVideoReceiveConfig, but mute and not display these streams when they are received.

Android is unable to connect with IOS if IOS is in the room first.
--- Possible work around is to have IOS connect to room last when using Skylink Media Relay.



Without Skylink Media Relay:

File transfer does not work fully between Android and Web:
  --- The only scenario that works is if Android enters the room before Web and receives from Web.





SkylinkConnection API changes:
