webRTC iOS example app.

Forked from newOcean. Updated to the latest webrtc iOS example code from google. Not sure the trunk directory is needed.

To Run example:

• Build this code for a device (iPad or iPhone).
• Open a Google Chrome browser (not IE, Firefox or Safari - spent a day debugging why Firefox was not working - CHROME!!)
• Open this URL: https://apprtc.appspot.com
• Ensure the camera on your laptop has an image
• Make note of the room number in the URL after loading web page
• Run the iOS app and type in the room number
• Stand back .... Should here feedback audio between your laptop and iOS device.
• NOTE - the audio is the only channel implemented by Google, the video render portion on iOS is not implemented yet.

UPDATE 11/14/13:

• Video support added!
• Now video and audio are both full duplex
• Code is not ideal, needs to be cleaned up, to repeat, CODE IS A HACK and needs clean up
• Big thanks to [Bridger Maxwell] (http://www.bridgermaxwell.com) for the webRTC objC video code - totally could not be done without his help, THANK YOU!
• This thread on google groups was VERY, VERY helpful
• These libraries are the key to bringing video to life:
  • ios-example/libs/libjingle.a
  • ios-example/libs/libjingle_media.a
  • ios-example/libs/libjingle_peerconnection_objc.a
  • ios-example/libs/libvideo_render_module.a

To build XCode iOS app only for device (not simulator):

• project location: webrtc-ios/ios-example/AppRTCDemo.xcodeproj
• Open the XCode project and set target for iPad / iPhone
• Build and run
• Should work without changes (webrtc branch 3.46)

To build the video and jingle libs yourself, which you can then copy back into the ios-example/libs directory:

• Download a copy of the Google WebRTC build tools and code here (webrtc branch 3.46)
• Copy the files in the webrtc_obj dir into this dir ...projdir.../trunk/talk/app/webrtc/objc
• Build the AppRTCDemo target: wrios && gclient runhooks && ninja -C out_ios/Debug AppRTCDemo
• Copy the resulting libs back into the Xcode project cp ...projdir.../trunk/out_ios/Debug/libvideo_render_module.a ...projdir.../ios_app/webrtc-ios/ios-example/libs
• I am not using the trunk dir provided in this repo. Using the Google trunk that you downloaded in step one instead.

Update 4/29/14:

• iOS7, Mavericks, and XCode 5.1 update!!
• Ensured my local repo was in sync with github
• Set SDK and target device to 7.1
• Compiled and saw over 100+ errors
• Determined that "Other Linker Flags" needed to be set to: "-stdlib=libstdc++"
• fixed all 100+ errors
• URL for stun server in JSON key changed from URL to URLS, so changed parser
• Ran client SW on my iPhone5 running 7.1
• Worked!

My Test setup as of 4/29/14:

• MacBook Pro wih OSX 10.9.2
• Chrome browser connected to apprtc.appspot.com
• iPhone5 (iOS7) connected to Xcode 5.1 via debugger
• Occasionaly, I hit an issue with the TURN server not being reachable and need to re-run the app. Some networks this is worse, e.g. home network versus work.

Contributing:

• Fork it
• Create your feature branch (git checkout -b my_new_feature)
• Commit your changes (git commit -m 'Added some feature' -a)
• Push to the branch (git push origin my_new_feature)
• Create a new Pull Request
• Please send in your changes!!

Again, this code needs a lot of cleanup, so please use at own risk. Enjoy!
