Rule of Thumb

Status code:

  • OOAD: In analysis or design phase.
  • WIP: working on WIP patch.
  • feedback(f): feedback a patch
  • feedback?(f?): WIP is ready for feedback grant.
  • feedback+(f+): Get positive feedback.
  • feedback-(f-): Get negative feedback.
  • review(r): review a patch.
  • review?(r?): patch is under review
  • review+(r+): get review+ and ready to check-in
  • review-(r-): get negative review feedback. Fix problems and switch back to r? again.
  • land: patch check in.
  • debug: Figure out the root cause of a bug/ try to repro that bug, etc...
  • file: file a bug
  • PTO: take personal leave
  • interview(I)
  • study: Spend time on domain knowledge study, such as multimedia transport technology, compress format, real-time rendering.
  • presentation
    • Write a personal blog, which is relative to work, such as articles on MozTech, or what you experience in a work week.
    • WIKI/ MDN article writing.
    • If you write a technical blog or anything relative to work, it's welcome to share it on weekly report.
    • Do a presentation of technical topics

Status code combination rule
Combine status code with "|". For example 

** OOAD|WIP

Which means you work on both OOAD and WIP in the last week.

land status code
If your patch is target for specific branch, instead of central, postfix branch version. For exp 

** land(1.4)

Media

Randy Lin

  • bug 996379 - OpenH264 decoder fail to decode the frame from B2G HW h264 encode
    • debug
    • OpenH264 decoder can decode image from frame, but frame device still have problem to decode image from openh264 encoder.
  • bug 1000013 - Have an mechanism to test the fault-tolerant with h264 video codec between b2g devices
    • WIP
    • Can create I420 frame and encode it successfully.

Alfredo Yang

  • Study b2g native class test on try server.
    • study
    • Pass test command via command line doesn't work. Now back to check how to use SpecialPower to invoke gTest on b2g try server.
  • Study ImageCapture API
    • study
    • Discuss wither others for implement plan.

John Lin

  • bug 989945 - [B2G][WebRTC] long video lag when using H.264 codec.
    • debug
    • pull jesup's lastest patch queue and check latency distribution again. The time from calling decoded callback to media pipeline is 50~100+ms. VP8 call has similar result.
    • find a issue after applying jesup's patch: there seems to be a problem in QCOM's codec that causes image quality degradation if no periodic I-frames.

Boris Chiou

  • bug 975346 - [LayerScope] LayerScope is not work while HWC is chosen
    • WIP | F+ | D
    • Problem: Any graphicBuffer lock/unlock in HwcComposer2D will cause the lock failed in ContentClientDoubleBuffered::FinalizeFrame().
    • I tried to test the gen lock problem on unagi, leo, and flame. unagi and leo are easy to reproduce it if I call lock/unlock often in HwcComposer. Flame is not easy to reproduce this issue, and it seldom uses HwcComposer. According to Peter's suggestion, I should figure out why Setting page doesn't use HwcComposer by dumping layer tree.
