Ongoing work
- Scope is still being determined and there is a master meta bug created
- bug 980768 [Stingray] TV support
- TV Components Overview
Key focus areas of the team
- bug 1067781 [Stingray] Card UI for Smart Screen
- bug 1067828 [Stingray] Interconnectivity
- bug 1067862 [Stingray] Remote Notification
Gaia
System Architecture
2-layered widget support- bug 983001- A prototype of 2-layered widget can be found at https://github.com/luke-chang/gaia/tree/TV_arch1
- Hybrid Widget Approach (more: https://wiki.mozilla.org/FirefoxOS/Stingray/Hybrid_Widget_Approach)
- meta bug - bug 1002336
Applications
- DLNA support - bug 984108
- Components Diagram
- SSDP advertising Service - bug 751172
- Http Live Streaming
- m3u8 parser
- media player with using Media Source Extensions API
Others
- Build system supports multiple devices -
bug 979784landed to master by Gary Chen- Step 1. Add 'GAIA_DEVICE_TYPE' flag in gaia build system.
- Step 2. New apps.list structure for multiple-devices.
- Step 3. Overwrite common-setting.json from build/GAIA_DEVICE_TYPE/settings.js
- Step 4. Remove distribution_tablet folder from gaia code base. bug 996461
- Step a. Let homescreen APP's build system support 'GAIA_DEVICE_TYPE' flag.
- Step b. Let wallpaper APP's build system support 'GAIA_DEVICE_TYPE' flag.
Web API
- TV Manager Web API - bug 998872
- It is on going to polish a first version then open to public space. ex: Bugzilla and dev-webapi@lists.mozilla.org.
- Input Ports Web API - bug ?
- The purpose is to let web app show media stream and detect plug-in status from HDMI/AV cable.
- It is on going to discuss for leveraging getUserMedia series Web API.
- HTMLMediaElement.audio/videoTracks Web API - bug 744896
- MediaStream
- Implement Track related methods and events in MediaStream.webidl - bug 985265
- Create a new type of MediaStreamTrack for text and metadata - bug 987501
- Expose a client UDP datagram socket API to web application - bug 745283
- Presentation API - bug 1069230
- mozWidget API - bug 1005818
Gecko
Media
- DOM Level
- Support HTMLMediaElement.audioTracks and videoTracks - bug 744896
- Probably won't implement the audio mixing and video selecting in our decoding pipeline.
- How to map AudioStreamTrack to AudioTrack? (Video as well)
- Proposal 1: Change the spec of MediaStreamTrack
- https://groups.google.com/forum/?hl=en#!topic/mozilla.dev.media/FOOHGdwD16Y
- Proposal 2: Implement the mapping internally
- Implement Track related methods and events in MediaStream.webidl - bug 985265
- Not necessary for this TV project, but would benefit the user experience of using front/end camera with getUserMedia a lot.
- Support HTMLMediaElement.audioTracks and videoTracks - bug 744896
- Internal Only
- Add a new kind of MediaStream to by pass our media pipeline - bug 987498
- aka. HWOverlayMediaStream.
- Construct a new kind of MediaStream, this would be an abstract layer, indicating its media resource is fetched from a particular hardware driver.
- By pass our MediaStreamGraph pipeline, and hook up its listeners with HAL interface specific to the platform.
- Create a new type of MediaStreamTrack for text and metadata - bug 987501
- In order to let MediaStream handle tracks such as subtitles, captions, metadata.
- Add a new kind of MediaStream to by pass our media pipeline - bug 987498
- HW Key Management - bug 989198
- Capturing & bubbling phase between system app & it's nested iframe. Wiki
- Work with Keyboard app.
- How to detect which keys are supported by platform?
- Allow nested oop <iframe mozbrowser> without nested content processes - bug 879475
- Just be transferred to stream 3.
Presentations
- Layers Architecture of System/HomeScreen embedded Apps
- OIPF Functional Architecture
- OITF Terminal Functionality
- Apps Runtime for Broadcasting Services
- TV Tuner Control API - Study
- Introduction of TV IG
- Media Efforts for TV
- Introduction of Http Live Streaming.
Backlog
- Introduce a new layer type to represent HW overlay frame.
- Introduce a new interface for compositor to pass position info into outside of Gecko.
- Introduce a new interface for decoding image through HW component.
- Introduce a fake tuner driver/HAL for B2G emulator.
- Feature detection for TV category. ex: 4 color keys / no touch.
