I built AppRtcDemo for iOS as demontrated on https://sites.google.com/site/webrtc/native-code/ios.I want to build my own webrtc demo application, so I copied all static libraries under "out_ios/Debug-iphoneos"  and all headers under "/talk/app/webrtc/objc/public/" to my iOS application project.The build process can be finished without an error, however, when application runs on my iPhone it crashed when 'RTCPeerConnectionFactory' initializing.My code is like:

[RTCPeerConnectionFactory initializeSSL];

_factory = [[RTCPeerConnectionFactory alloc] init];


I do the same things on an earlier version webrtc checkout(current version is updated yesterday, earlier version was checked out about 3 month ago), all things goes well!

I don't know why!

I fixed it!The build errors is because of lack of "VideoToolbox.framework"!After I added it to my second project all thing goes well!
