I pushed the commit that both updated the scripts to use the GStreamer 1.4 branch which added the use of VideoToolbox on iOS and also the change to build.sh which added the linking against the VideoToolbox framework in the same commit so that people wouldn't have problems. Are you using master of openwebrtc?

[mccob]

yes followed update webrtc here : https://github.com/EricssonResearch/openwebrtc/wiki/Building-OpenWebRTC

[mccob]

downloaded again and build again, still same thing

[superdump]

Do you have at least the iOS version 8 SDK? VideoToolbox only arrived in iOS 8. But you probably want to updated to iOS 8.1 that was released yesterday.
