  • bug 960243 - Bad audio quality with MediaRecorder / JW
    • resampler/opus encoder buffer problem, transfer to JW
    • cause: frame number (after resampling) exceeding the length of an Opus packet and resulting in frame loss and a discontinuous tone.
    • fix: calculate in/out frame numbers before resampling so that frame number after resampling will be exactly the length of an Opus packet.

  • bug 946241 - [Camera][gonk-kk] Porting GonkCameraHwMgr /solomon
    • Fixed the problem Camra previewing(blank screen) in Nexus-5
  • bug 946952 - Camera preview cannot be render with HwcComposer2D /Solomon
    • By observing the layer tree from LayerScope, the background layer is sometimes be fed into composer with ThebesLayer, such that HwcComposer2D cannot use it to do HW composition. So this issue is not originated from HwcComposer.
    • In FrameLayerBuilder, the The back ThebesLayer previously contained content that couldn't be optimized to a ColorLayer, and once it can be, it decide to keep using the ThebesLayer since it's already allocated. So the improper thebeslayer will make the camera previewing be composited by HwcComposer2D.
    • Matt Woodrow will look into this problem from upper stream function.
  • bug 961963 - [Nexus 5] [gonk-kk] Black screen when scrolling the screen in the apps /Solomon
    • Trying to reproduce this problem with and without APZ disabled.
  • bug 946245 - [Display][gonk-kk] Porting GonkDisplay, nativewindow and libui /Solomon
    • Porting nativewindow relative classes for corresponding KK: GonkBufferQueue, GonkNativeWindow, GonkNativeWindowClient, and GonkConsumerBase.
    • In KK, the class BufferItem is migrated from BufferQueue to IGraphicsBufferConsumer, which leads to BufferItem manipulating functions(acquireBuffer, queueBuffer, dequeueBuffer...etc) have to be modified carefully. Meanwhile, due to gonk's custumization also add some data member to carry gecko specific data, the relative refactoring need to consult with Sotaro in advance.

Input

    • Need to pass event not going through DOM.
    • (Support Bug 924692) To select a text after being long-pressed.
    • FrameScript already can receive "LongPress" event from APZC or non-APZC.
    • Study Web API about Selection/Window. Figuring out how to manipulate it after receiving "LongPress" event.
