Agenda/Notes:
1) Stand-ups:
- Active developers will give a 3 minute (or less) stand up focusing on -

- what are you moving onto next?
- have you hit any problems (especially unexpected problems)?
- jesup -
- Finishing latency monitoring -- remaining PC and Mac issues
- Looking to land latency monitoring
- Some cool work happening with Data Channels and uproxy
- Will extend the AEC tail to 128ms and try to land in time for Fx 27
- padenot -
- Working through the latency optimization regressions
- New graphs show the latency is much improved. Paul will upload pdfs for others to see
- Doing some work on the Web Audio spec
- Planning to take PTO soon (not sure when yet)
- ekr -
- Went to Taipei first and then Portland
- Patch for TURN TCP is largely written:

- Gutted the patch for Bug 878941 - should upload top half in the next day or so
- Iffy for Fx 27
- Will land pref'd off
- Update from Taipei:
- NSS patches will land in next 2 weeks
- e10s filtering back will land in next 2 weeks
- Reviewing video conduit patch
- Heard feedback in Portland from talky.io guys. They are looking for:
- connectivity rates to improve
- Better AEC
- Multiple stream support
- Want integration with Web Audio
- Want rebroadcast incoming->outgoing (2nd create offer is not working)
- abr -
- Continued IETF prep work
- Bug 784491 (Bundle) -- still making progress, albeit at a rather slow pace due to IETF work.
- ehugg -

- landed Bug 928221, weakConcretePtr workaround (filed Bug 928535, Support WeakRef's from c++ to JSImplemented webidl objects)
- landed Bug 928060, Parse ?transport=[udp|tcp] in TURN uri
- posted implementors notes on gUM & peerConnection constraints on media-capture and webrtc lists respectively
- Hope to post something on our RTCStats implementation
- PTO Friday?
- bwc -
- Working on test harness for acain
- Moved forward on Bug 906990
- Started implementation for about:webrtc
- close to haing log filtering display working
- gcp -
- WebRTC Android UI tests
- Minor cleanup work/debugging
- Will look at Load Monitor patch https://bugzilla.mozilla.org/show_bug.cgi?id=902000
- Make adaption sit behind a pref?
- suhas -
- Slow progress last week due to IETF Deadline till 10/21
- Bug 909524 - Bug 923770 has been merged to Talos repository and should land today (:jmaher). This invovles a major refactor within Talos. Started working to re-base the patch in Bug909524 to the new framework style.
- Next Steps: Get the patch re-based and working on Mac/Linux. Write up on the Chrome's Perf Analysis and Talos applicability.
- Unfortunately, have to miss today's meeting due to Physical Therapy Session
- ctangira -
- Couldn't make the meeting today
2) Bugs/issues for discussion: a) Image freeze reports -- If you see these, please let Maire know and try to get logs.
- Is anyone seeing these?
- Maire will reach out to QA
b) Audio quality - overview of where we are and short term plans.
- Land the rest of latency monitoring (jesup)and clean up regressions from latency improvement patches (padenot)
- more latency testing
- move AEC for gUM
- improve AEC quality
c) Any problems or issues that should be discussed -- or Any heads up for the group
- Remove support for peerConnection deprecated functionality we added warnings for in FF24, in FF27? (push from Bug 923904)
- privacy review for including IceCandidate pairs in RTCStats
- love for Bug 917980?
- [abr] Yeah, I'll take this one. I suspect it's in the code that I'm familiar with.
d) Reminder to dogfood whenever possible: Use WebRTC for chats within the team whenever possible (prefer to IRC, etc if possible)
<Read only section>
Notices:
- Reviews:
- Reminder to handle review requests in a timely manner (previously discussed), and to raise any design issues early if possible, preferably outside of the the review process (in the bug, email, IRC, calls, whatever makes sense)
- Req for WebRTC Media platform engineer is open. Talk with Maire if you have a referral
- Looking for QA tester for WebRTC (reporting to Marc Schifer, but dedicated to our team for the foreseeable future). Talk with Maire if you have a referral.
