Tuesday, Oct 15, 2013, 8am Pacific:
Agenda/Notes:
1) Stand-ups:
- Active developers will give a 3 minute (or less) stand up focusing on -
- what are you currently working on that the team is following/tracking (please give the bug number) and when do you think you'll be done?
- what are you moving onto next?
- have you hit any problems (especially unexpected problems)?
- jesup -
- DataChannel issues in talkilla appear to be ICE/mtransport -> ekr/ehugg (bug xxxxx)
- Audio latency graphs look reasonable-though-not-great on linux (~115ms + network with padenot's to-be-landed patches)
- getting them up on mac/linux. Mac is much better.
- considering cherry-picking longer AEC tail for 27
- need to look into longer tails for Android/B2G (AECM - mobile AEC)
- Preparing to move AEC to getUserMedia and hooking to cubeb - will try hooking glitch detection to AEC reset in the process
- padenot -
- Major latency improvements in patches that are about to land for Android (Nexus 4), Linux, and Mac
- Latncy patches are all r+'d and green on TRY
- One more patch that is about to go out to Roc
- ekr -
- Ekr is in Taipei all week
- TURN TCP will be up for review soon (within the next week)
- abr -
- IETF prep (partial offer/partial answer work)
- minor progress on bundle functionality (Bug 784517)
- ehugg -
- Bug 845007 - Port Control Protocol (PCP) Implementation for WebRTC NAT Traversal, need landing plan and review.
- Bug 923190 - about:license should include the license for libpcp, ready to go with above patch.
- Bug 925896 - UAF in signaling_unittests, patch up.
- Bug 908794 - Allow changing codec order by JS between createOffer/createAnswer and setLocal/setRemote, in progress
- Bug 916429 - No a=sctpmap for datachannel in SDP, pushed to FF27
- Bug 921604 - Signaling unittest trickle tests fail on machines with multiple addresses, pushed to FF27.
- jib -
- Landed Bug 917328 - convert IPeerConnection.idl to webidl
- Bug 902003 skeleton patches up for review with Byron's dispatch. Works with ice candidate pairs in Bug 906990
- Am posting constraint implementation feedback to list
- bwc -
- Landed more of bug 906990
- Working with jib's patches
- Very rough webrtc page -- grabbing stats from other tabs
- gcp -
- No news, unless I didn't mention before that Google rewrote the Android backend and this will affect stability/workload for Firefox 28.
- May get reinforcements.
- Anyone happen to know the audio/video status on tegra/panda boards?
- suhas -
- IETF work week - getting docs updated, reviewed and so on.
- End To End Latency Measurement:
- Waitng on jMaher's patch to land which involves re-architecting parts of Talos.
- Ported existing patch on Linux to test its working.
- Next Steps: shall wait for jMaher's Talos patch to land
- Bug 845007: Investigating to setup few unit tests to test PCP message exchanges.
- ctangira -
- Working on bug where we can't display video if user doesn't allow audio
2) Bugs/issues for discussion:
a) Image freeze reports -- If you see these, please let Maire know and try to get logs.
b) DataChannel set up is unreliable (Bug 925880) - Looks to be an ICE/transport failure
- Ehugg is going to look into it
c) Audio quality - overview of where we are and short term plans.
- finish and land the rest of latency monitoring (jesup)and known latency fixes (padenot)
- more latency testing
- move AEC for gUM
- improve AEC quality
d) Any problems or issues that should be discussed -- or Any heads up for the group
- --disable-webrtc - what's in/out? - What's it for? (doesn't unagi have webrtc now?)
- Still useful on systems like BSD and temporarily for some B2G work
e) 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.
- This week:
a) Meeting with tokbox today at 2pm, pacific b) Follow up with line on connectivity issues
