GFX (milan)

• OMTC
  • On XP in decent shape; we will probably create a separate (temporary) pref so that we can just enable it on that platform.
  • On Windows 7, we have some performance regressions we're still trying to figure out if they're real or not; switching to OMTC default on that platform will likely be delayed by a week.

• Skia
  • The main vector of work is going through reftest failures and fixing them. So far, great majority (all) have been actual Skia "bugs" (in some cases, Skia purposely plays loose with the results in order to gain performance, though not all of those cases actually result in improved performance.)

• V-sync (butter, silk, whatever we're calling it today)
  • Implementation details being discussed between Taipei and the rest of the graphics team.

• APZ
  • low-res tiling in progress
  • discussing what homescreen changes proposed for 2.0 mean for APZ

• E10S
  • Beyond OMTC, we haven't yet scheduled anything to provide support for the E10S effort.
  • Still need to complete the prioritization conversation.

Media (jesup)

• Initial H.264 hardware (OMX) support landed for B2G, preffed off -- bug 911046
  • patch for vp8 OMX support in the works
• Looks like we found the primary source for many media oranges - misuse of active timers (use from more than one thread) -- bug 998168 - fingers crossed! Thanks to jwwang!
• Expecting to land update for webrtc.org to 3.50 as soon as we have android video/audio capture merged
• Some fallouts from MediaStreamGraph and AudioStream refactors that landed; being worked

WebAPI (overholt)

• No update this week.

Quality Programs

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

MemShrink (njn)

• No update.

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.)
