  1. 1. WEBRTC ON MOBILE DEVICES: CHALLENGES AND OPPORTUNITIES Vladimir Beloborodov Technical Manager / CTO at Mera Software Services + =
  2. 2. WebRTC
  3. 3. WebRTC is a technology for peer-to-peer exchange of media (audio, video) and data between web*-clients in (near) real time * Note: web here is in a broader sense than just browsers and in-browser apps
  4. 4. Web as in web-browser? Yes! But more than that
  5. 5. Data
  6. 6. Neophyte View on WebRTC Data

  8. 8. Amir Zmora @AmirZmora If I Hear of Another New Cool #WebRTC Talking Heads Service Im Going to Scream http://bit.ly/1KuKCnZ Original tweet: https://twitter.com/AmirZmora/status/602817737728126977
  9. 9. Contact Centers Enterprise Telecom Carriers / OTT Communication features in consumer electronics Telecom: A No-Brainer Vertical
  10. 10. Telecom View on WebRTC Data Shared Screen* * Screen sharing is coming to the WebRTC standard
  11. 11. ommunication can be more than just plain Telecom
  12. 12. Human-to-Human Human-Machine Interactions Machine-to-Machine (?) Why not?
  13. 13. Noise Data
  14. 14. Note that WebRTC can also be a great match for many other new and emerging technologies
  15. 15. Data Natural Language Processing
  16. 16. Communication-Centric Model Changes 19th century 2000s: Communication as a product 2000s 2010s: Communication as a service
  17. 17. Into Domain/Problem-Centric Model 2010s : Communication as a feature, Communication as a function
  18. 18. Communication as a Function Context-awareness and context-preservation Instant availability (in the given context) Integration with/into problem-specific tools Selection of communication options/channels Personalization (user preferences/profiles) Integration with the surrounding environment
  19. 19. Remote Support. Assistant-as-App. Personal consulting and coaching Post-training performance support Amateur support. Situational assistance. Augmented-reality-based guidance

  21. 21. http://www.onato.com/projects/vex.html VEX ~ Remote Insurance Appraisals Users can video chat with the appraiser so that appraisals can be quickly and effectively performed from the office. Video sessions are archived for possible liability disputes. Hi resolution photos can be taken by the appraiser at any time to ensure all details are captured.
  22. 22. Social Engagement. Accessibility. Public reporting and journalism Elderly support services Sign-language translation services Assistance to blind people
  23. 23. http://www.bemyeyes.org/
  24. 24. Peer-to-Peer Interactions. CDN. Remote control services and functions Robotic telepresence and avatars Content delivery services Secured peer-to-peer transactions

  27. 27. http://www.doublerobotics.com/ Caveat: Their SDK only used WebRTC voice and video. Data channel anyone?
  28. 28. Time for quick demo Try it!

  30. 30. Communication as a Function makes perfect sense in many desktop-based scenarios
  31. 31. Side-note: Desktop goes mobile too Source: http://thenextweb.com/mobile/2012/02/21/ubuntu-for- android-could-turn-your-phone-into-a-powerful-desktop-computer/ Source: https://www-ssl.intel.com/content/www/us/en/compute-stick/intel-compute-stick.html Source: https://www.apple.com/macbook/
  32. 32. Communication as a Function can be done with several Telecom or Web technologies
  33. 33. Native or hybrid application logic Web-application logic WebRTC API(s) in some other programming language(s) Implementation of the Web API part of WebRTC This API is standardized by the WEBRTC group in W3C (including interactions with other parts of HTML5) Implementation-specific API Implementation of the RTC mechanisms of WebRTC These mechanisms are standardized by the RTCWEB group in IETF (NAT traversal, media negotiation, mandatory codecs, and the like) Underlying platform
  34. 34. Enhanced ICE-based NAT Traversal Secure media and data transport Common subset of media codecs Signaling over existing peer connection and more

  37. 37. WebRTC on Mobile? Choices, choices Web App Native Mobile App Hybrid Mobile App
  38. 38. WebRTC-related Considerations WebRTC libraries for native apps WebRTC direct support in WebView WebRTC in embedded browser WebRTC in 3rd-party browser apps
  39. 39. Some General Considerations Native look and feel on target platforms Application responsiveness. Usage of gestures. Native platform capabilities. Storage options. Support of external H/W devices / accessories Access to local media sources and outputs
  40. 40. Some More Considerations End-customer preferences / requirements Support for prev. versions (platform / browser) Required skillset and dev tools
  41. 41. WebRTC Options on Android Open-source libs Google WebRTC OpenWebRTC (Ericsson) WebRTC in WebView Starting 5.0 Lollipop Embedded browser Starting 5.0 (with Chrome) ++ 3rd-party browsers Chrome, Firefox, Bowser * * Bowser: https://getbowser.appspot.com/ ++ Not guaranteed in case of vendor-customized Android firmwares
  42. 42. WebRTC Options on iOS Open-source libs Google WebRTC OpenWebRTC (Ericsson) WebRTC in WebView No native support Embedded browser No 3rd-party browsers Bowser * * Bowser: https://getbowser.appspot.com/
  43. 43. Google WebRTC Ericsson OpenWebRTC WebRTC Open-Source Implementations* * Mozilla plans to join the club too, offering their Firefox WebRTC engine. * For ORTC, the ORTC project offers their own open-source prototype.
  44. 44. Diversity of H/W Platforms and Options
  45. 45. Preserve video proportions UI and UX with WebRTC One screen layout may not fit all Device orientation affects both UI layout and camera layout Preview of local front camera normally mirrors the user
  46. 46. WebRTC App Behavior Background mode considerations Wi-Fi only / Wi-Fi and Cellular Lighter comm. channel options for narrow-bandwidth conditions Handle edge cases and errors
  47. 47. Advanced and hack-ish topics Codec ordering in SDP matters. Changing it may help, but you must know well what you do. (Pre-)balance UX and system load with WebRTC constraints Find out what codecs, if any, enjoy H/W acceleration on platform/lib
  48. 48. Hybrid Mobile Applications A typical definition: Applications combining elements of both native applications and Web applications.
  49. 49. How Well Can Web Play Native? App / domain logic and models App UI* Performance-demanding features and capabilities * This may work great for certain apps and customers. Yet, generally, be careful.
  50. 50. JS-Hybrids: More Than One Approach Approach Example dev options Packaged web apps Microsoft ManifoldJS WebView UI apps Cordova / PhoneGap JS-based apps with shared native UI NativeScript JS-based apps with per-platform UIs React Native

  52. 52. Between here and the horizon WebRTC official standard (WebRTC 1.0) Object RTC (ORTC) and WebRTC 1.1 Microsoft Edge with ORTC on board Screen sharing. Many other additions. WebAssembly + WebRTC
