SDK Release 4.0.0

SDK Release 4.0.0 - 28 September, 2017

NOTE: xCode 10 has dropped support for libstdc++. It is necessary to replace dependencies for libstdc++ with libc++ in your iOS project to build with xCode 10. No modifications needed to be made to the iOS SDK for this change.


  • Added support for saving files locally on device (note: requires Privacy - Photo Library Additions Usage Description and Privacy - Photo Library Usage Description permission in info.plist)
  • Better packet queuing for low bandwidth publishing (requires server v4.0.0)
  • Fixed - Crash with ABR publishing on iOS 11
  • Fixed - A/V sync drift with two-way streaming

The following are now required for Apps that utilize the iOS SDK:

  • libbz2.1.0.tbd - Could not add to SDK as only object files can be added as linked frameworks and/or libraries. Used in decode buffer.
  • VideoToolbox - Adding to the SDK still throws build dependency issues for applications. Needed for encoding/decoding.
