Streaming Media
WebRTC
- bug 902856 - Should MediaEngineDefaultAudioSource generate real data? / slee
- landed
- bug 914494 - getUserMedia application notification when a higher-priority user grabs the hardware / slee
- Need to discuss with jesup
- bug 904025 - [B2G][WebRTC] media stream should stop when another high priority application request microphone resource /slee
- r+'ed and fixing some compiling errors on linux.
- bug 896391 - memcpy from camera preview's GraphicBuffer is slow / slee
- Co-work with the vendor
- The todo list of WebRTC / slee
- Thanks for the help of John, Patrick, SC and ShianYow.
- https://trello.com/b/wN1IEGhv/webrtc-1-3-planning
- bug 911046 - WebRTC OmxCodec coding path support / John Lin
- use graphic buffer in decoder to reduce CPU usage (from 7x% to 4x%)
- issues found
- frame drop
- camera freeze
Graphic
- bug 907048 - Skip colorlayer if other opacity layer just covers the colorlayer region / Peter
- Landed
- will create another bug for layer tree parsing before GPU/HWC composition
- Vsync proposal study / Peter
- bug 907108 [B2G][Helix][Gaia][meijinfang]The orientation of iamge will be inverted in the edit view of gallery / Peter
- Checking
- bug 893304 - Convert CanvasClientWebGL (and Host) to the new textures /Morris
- wait for review

- study
Nexus 4 JB support
- bug 912373 - Support colorlayer for generic HWComposer, like MDP /Jerry
- Nexus 4 can use hwc with one color layer now.
- Working on:
- 1. 2 or more color layers support.
- 2. optimize color layer buffer size
- 3. optimize color layer buffer filling performance
- Working on:
- Nexus 4 can use hwc with one color layer now.
