Chrome M30 WebRTC Release Notes

[Vikas Marwaha]

Hi,

Please find below WebRTC Release Notes for Chrome M30. Below is the list of major changes:

Features:-

Issue 1571 :- Add support for explicit device enumeration in JavaScript, via MediaStreamTrack.getSources. Applications can now manage which audio input and video input devices are used themselves. Audio output is not yet implemented.
Issue 1425 :- Add TURN/TLS support to connect to TURN server via TLS using turns: TURN URI's.
Issue 1493 :- Add support for SCTP based data channels. Currently, it is behind a flag for M30.
Issue 1408 :- Add support for sending binary data through data channel. You would need to enable SCTP flag for M30.
Issue 1430 :- Add support for Reliable data channels in chrome.You need to enable SCTP flag for M30.
• Issue 1864 :- Implement cert caching for DTLS. DTLS cert generation has been moved into the browser with persistent caching. This improves call startup time when using DTLS. You need to specify 'DtlsSrtpKeyAgreement: true' when creating peerconnection to test this feature.
Issue 1837 :- Wire up to have padding packet generation be driven by pacer.
• Issue 1897 :- Add support for Error concealment when NACK is disabled.
Issue 1881 :- Add support for maxaveragebitrate. You should now be able to control the opus bit-rate with maxaveragebitrate fmtp parameter in sdp.
Issue 79949 :- Implement CreateMediaElementSource() on audio/video elements. As an example you can use this API to apply effects on an audio tag and play it back using WebAudio.
Issue 262117 :- Multiple media streams with audio tracks can now be added to a peerconnection. However, only one microphone source at a time is permitted as currently WebRTC supports only one audio processing module (APM).
• iOS :- An ObjC PeerConnection API is now available for signaling & one-way audio (README). Known issues include two-way audio (2191) and video support (2168).
• Android :- (RTP) data channel support (1679)

Bug fixes :-

• Issue 1718 :- Updating local description fails when using DTLS.
  
• Issue 261865 :- Crash while on video call.
  
• Issue 263003 :- Chrome OS: WebRTC screen capture is broken on ARM.
  
• Issue 267880 :- Populate labels only if permitted in mediaStreamTrack.getSources().
  
• Issue 2183 :- Shutdown-time fixes.
  

Announcement:

• Code that used to live in code.google.com/p/libjingle now lives in https://code.google.com/p/webrtc/, under the talk/ directory.
