    • 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

  • 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.
