Gaia/Team/Taipei/Meetings/2013-11-19

GFX (milan)

• Have the preliminary priorities for Q4, Q1, Q2 next year
• Sorting out the scheduling
• Big part of the plan is to finish the large changes around Moz2D and OMTC

Media (mreavy)

<Read Only>

• Working to update libvpx to 1.2.0, which will gets us VP9 support (see bug 763495)
• Media playback team is having their work week this week in Auckland
• Opera's latest release supports gUM and WebRTC: http://my.opera.com/ODIN/blog/opera-desktop-18-released
• The WebRTC team and the Media Recording team are working to enable all the WebRTC APIs (gUM, PeerConnection, and Data Channels) for B2G v1.3. Audio-only calls on B2G work now with mozilla-central and 2 patches applied.

WebAPI (overholt)

<Read Only>

• Still working hard to get async IDB in workers for end of December (post-gecko 28)
• marcosc almost ready to publish research and recommendations on "standalone" web apps

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

MemShrink (njn)

• The trees were shut again for several days due to OOM-related Win7 M-2 and M-bc test failures. Contributions to the post-mortem and suggestions on how to prevent such problems again are welcome!

• Matt Woodrow fixed a bad gfx leak that was causing very high memory usage (reported under "heap-unclassified") on Macs when a browser window was minimized. Nick Cameron added a memory reporter for this memory so it will be reported properly in the future. (Sadly enough, Nick wrote that reporter six weeks ago but it bounced due to it causing PGO bustage on Windows -- if it had been present, the leak could have been fixed more quickly. Thankfully the PGO bustage has disappeared now.)

Roundtable

(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

<Read only beyond this point>

Mailing List Threads

(Threads that are likely to be of interest to engineering from various mailing lists.)

Good Reads

(Links to blog posts, books, videos, etc. that you think will be of interest to others.)
