Gecko - Plan and Ongoing Work

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

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.

• 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.

• 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.
