Rule of Thumb

Status code:

• OOAD: In analysis or design phase.
• WIP: working on WIP patch.
• feedback?(f?): WIP is ready for feedback grant.
• feedback+(f+): Get positive feedback.
• review?(r?): patch is under review
• review+(r+): get review+ and ready to check-in
• land: patch check in.
• debug: Figure out the root cause of a bug/ try to repro that bug, etc...
• file: file a bug
• 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

Chiahung Tai

• bug 985785 - Video tag memory leak while the video frame are not displayed on B2G
  • Resolved invalid.
  • This bug can't reproduce in latest codebase.

• bug 992842 - [Camera][B2G][Nexus 5] No camera preview in Nexus 5 FX OS build.
  • WIP
  • Try to find root cause. Suspect this is caused by Qualcomm driver issue. Need info Michael Vine.

• bug 970725 - Adapt gUM capture resolution based on encoding resolution
  • Use stopPreview/startPreview instead of stop/start camera. Reduce the resolution switch from seconds to hundreds ms.

• bug 968707 - Cavas.ToBlob is slow on B2G
  • WIP
  • Canvas.ToBlob is used in FX OS Gallery APP. This bug is trying to improve the processing time of JPEG encoding from canvas to JPEG. OpenMAX JPEG is not working in Qualcomm solutions. So try to use OpenCL to accelerate JPEG encoding/decoding. MAIDAI can support OCL. This bug could fully utilize the multiple cores HW for encoding/decoding. I focused on tracing JPEG source code now.
