webrtc build on ios

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

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
• 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.

My Test setup:

• MacBook Pro wih OSX 10.7
• Chrome browser connected to apprtc.appspot.com
• iPad 2 (iOS6) connected to Xcode 4.6.3 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

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