Media/WebRTC/2013-01-29
1/29/2013, 9am Pacific
Notes:
1) A/V quality, Interop with Chrome
- Where are we?
- AEC landed. Magic tuning parameter media.peerconnection.capture_delay defaulting to 150ms
- jesup finds on Linux first call has 400+ms delay (too much for 150 setting), second and subsequent have ~200ms (cancels with 150ms setting).
- working pretty well (especially for a demo)
- nor planning to uplift to Aurora
- Need to hook up A/V sync correctly between audio and video conduits
2) Blockers to PeerConnection, DataChannels for Desktop: where are we?
- What is blocking us from pref'ing these on? (Bug 796463 has dependencies now)
- Audit/Clean up buffer handling in nICEr STUN code (bug 825927)
- 2 of 3 have r+, jesup will land. Need to be upstreamed (not simultaneous)
- 3rd needs minor review and license review. (waiting on gerv)
- Updating webrtc.org code (which breaks Android) (Bug 830247)
- 3.20 ready to land - later this week
- Enabling echo canceller (Bug 818670)
- Audit/Clean up buffer handling in nICEr STUN code (bug 825927)
- Highly desired:
- Need to clean up DataChannels to work without PC connections
- Want to resolve open security bugs that are sec-moderate and higher
3) gUM blockers for release: where are we?
- UI: Bug 827145 (Dao) and Bug 825804 (up for review to gavin)
- Additional investigations
- jesup is looking into failure to exit while gum is active - weird GC/CC interaction?
- Bug 829907
- jib is looking into crashtest leaks - possibly related to the above
- jesup is looking into failure to exit while gum is active - weird GC/CC interaction?
4) Android work/status
- OpenSL support
- Looks like Google isn't updating the OpenSL code in webrtc.org
- DataChannels are working
- yeah! (lots of celebration)
- mobile datachannel demo just started working!
- Branch builds (Alder) up and running
- need to disable v6 and x86
- Choice on how to focus video work
- Currently uses JVM
- dmose has built 3.12 and verified it works on his phone
- trying to merge them over may cause threading issues
- or go the B2G route, and use v4l backend
- Currently uses JVM
- Gory details of work linked to at bottom of page
- WMC - what phones exactly will be used?
5) Discuss any current problems for people or issues that haven't been discussed -- or Any Heads up for the group
- No meeting this week due to work week in Billerica/Boston - please reach out in email or on irc if you need help with anything and aren't attending the work week
6) Testing
- [jsmith] Two one off crashtests patches out, one checked in
- [jsmith & whimboo] Met yesterday about for another planning meeting for going forward (https://etherpad.mozilla.org/webrtc-method)
- [jsmith] Desktop gUM testing to sign off is my next objective along with the associated automation
- [kbrosnan] Has started playing around with the WebRTC MWC script with the social api demo with the android build
- Barrier (Product) - Need a better understanding of the timeline for android webrtc
7) REMINDERS for upcoming meetings:
