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 -
    • Cleaning up latency patches, putting up for review tonight
    • A/V sync problems - prioritizing the review of bug 864654
    • Android 24 is having a crash problem that is specific to Android. Looks like we have a root cause fix.
  • ekr -
    • 1st major e10s bug is just about ready to land (Bug 869869)
    • Other bug is on target (Bug 870660)
    • Benchmarking is continuing - will be handed off to another developer
    • Fixes for TURN - Google's TURN server is busted again - should fix and land bogus candidate bug & will give to Byron as a priority (Bug 908740)
    • Anthony will find someone to verify TURN fix if we can explain how. Ekr will do this.
    • TrickleICE is taking longer than expected, but still hoping to land this week
  • abr -
    • 906843 (performance instrumentation) - landed, merged to m-c
    • 880067 (rtcp-fb) - patch needs nit fixes, should land today. Unit tests have more substantial comments, will take a bit more time (maybe tomorrow).
    • 784491 (bundle) - Plan to begin work on Friday / Monday
    • This week - Sitting with Byron in MTV, hope to make some IETF draft progress
  • ehugg -
    • Everyone needs this in their .mozconfig as it is now on the builders except Windows: ac_add_options --enable-warnings-as-errors
    • Landed 909179, 907353 and 844071 late last week. SDP now has three more lines by default: a=rtcp-mux, a=setup and a=connection. Still looking for bugs caused by this or tests that need updating.
    • bug 901560 has an interim patch that should land with 26 and a final patch that should land with 27 unless we deem in it urgent enough to uplift.
    • bug 908794 - first SDP editing bug. New sdp_compare function may be large in order to accomodate line-by-line error reporting.
    • bug 842549 - Do I need to help on this to get it in FF26.
    • On jury duty next week.
  • jib -
    • Worked on Bug 882145, gUM constraints (facingMode)
      • Have working patches up for mandatory constraints.
      • Still need to work around Bug 767924 (webidl unions) and optional constraints algorithm.
    • Landed Bug 903741, readable peerconnection error messages thrown
      • Contains unittests that verify error messages are readable on all platforms
      • Awaits Aurora approval (with dependent bug 905392)
  • bwc -
    • Starting his second week
    • Focusing on Bug 906990
  • padenot -
    • Working on 1-1/2 WebRTC bugs for the next week. Thinks it will be done in time for Firefox 26 uplift.
  • gcp -
    • Bug 902431 and friends. New repro steps seem ok
    • Seeing a deadlock in ProvideCameraFrame/SetRotation, investigating
  • suhas - is working part-time while on travel - working on bug 909524 (setting up tests to measure/monitor end-to-end audio quality in automation similar to Chrome)

2) Bugs/issues for discussion:

  • TURN bugs (905150, 904598)
    • Needs to be tested and verified so we can uplift into Firefox 25 before it goes to Beta
  • Audio quality - overview of where we are and short term plans.
    • Need to land latency plans and finish clean up of final bugs targeted for Firefox 26
    • Need to reproduce and quickly narrow down any new latency issues on Firefox 25 and 26 (which have the fix for Bug 884365)
  • Ekr hasn't been noticing video stalls this week when doing back-to-back video calls on the same machine (two separate tabs, same browser) using a Firefox Nightly debug builds. If Ekr (or anyone else) sees this again, he'll file a bug
  • Dogfooding
    • Use WebRTC for chats within the team whenever possible (prefer to IRC, etc if possible)
  • Any problems or issues that should be discussed -- or Any heads up for the group
    • None mentioned
