      1. ipc_video_decoder.cc/h is media pipeline filter which use the gpu decoder facilities in video stack. it is only enabled when (a) hardware composition is on (b) hardware decoding command line is on (c) h264 codec is specified.

2. gpu_video_service.cc/h is a singleton in gpu process which provide video services for renderer process, through it we could create decoder. ( in my imagination, in the future, we could create encoder or capturer too)

3. gpu_video_decoder.cc/h. abstract interface for hardware decoder.

4. gpu_video_service_host.cc/h is singleton in renderer process which provide proxy for gpu_video_service.

5. gpu_video_decoder_host.cc/h is proxy for gpu_video_decoder. (1 to 1 map).basically there is one global GpuVideoService in GPU process, one GpuVideoServiceHost in Renderer process. for each renderer process, there are could be multiple renderer view, each could had multiple GpuVideoDecoderHost the connect to GpuVideoDeocder through GPUCHannelHOst/GpuChannel.

6. gpu_video_common.cc/h: IPC message definition and pickle/marshaling support.

ISSUES:

1. in media pipeline, we need let decoder to determine if bit stream filter should be used instead of let command line to determine it.
2. stop readback from D3D surface use ANGLE.
3. Flush logic still need fine tuning.
4. CreateThread in GpuVideoDecoder, and post message in message handler, and derived classs handle message loop. ?
5. Error handling.
6. Input ring buffer implementation. Current impl is naive.
7.Add output queue for MFT decoder.
8. Query Capabilities at GetVideoServices()...

      Clean up third_party/cld. · 65127279
      jshin@chromium.org authored 
      1. Remove files we don't use that come from toolbar
2. Simplify the directory structure by removing the redundant
intermediary directories bar/toolbar/cld/i18n

This will bring CLD a step closer to where it can be open-sourced separately (or along with CED for encoding detection.). It's not there yet.


In addition to the clean-up, change |LanguageCode*| return 
'nb', 'he', 'fil' instead of 'no', 'iw', and 'tl'. 

Also, use LanguageCodeWithDialects instead of LanguageCode to get 'zh-CN' 
instead of 'zh'. This is to simplify the 3-way mapping between 
Chrome's UI locale code, CLD's language code and what's accepted by 
Google Translate. It's also another preparation for open-sourcing because
we'd better use the standard code rather than the obsolete code like 'iw'
when open-sourcing.

      More WebKit API action (chromium side). · da00a288
      darin@chromium.org authored 
      Adds the following methods to WebKitClient:

  decrementStatsTable
  incrementStatsTable
  traceEventBegin
  traceEventEnd

The implementation of initV8CounterFunction is now a no-op.  V8Proxy.cpp no
longer calls it, and I moved the corresponding work out of WebKit.  The
embedder now calls the appropriate V8 API before initializing WebKit.

Includes some cleanup to WebString and WebCString.  I decided that I prefer
"data" over "characters" since the latter may be confusing in some cases.  For
example, the elements of a WebString or WebCString may not be individual
characters but may be part of a character.  "data" is also consistent with
basic_string<T> and so should be plenty familiar.

There is wanton disregard for the Chrome+JSC build in this CL, but that's
OK.  We have already crossed that bridge.

      Audio related IPC messages and handlers from browser to · 6f56d48b
      hclam@chromium.org authored 
      renderer
1. Added 4 IPC messages and corresponding handlers for
audio:
  - RequestAudioPacket(int stream_id)
    Browser process is hungry for audio packet, notify
    renderer process to provide more.

  - NotifyAudioStreamCreated(int stream_id, SharedMemoryHandler
buffer, int len)
    Notify stream created event and provide buffer for
    filling in the future.

  - NotifyAudioStreamStateChanged(int stream_id, enum state,
nt info)
    The internal state of the audio stream has chagned,
notify renderer
    process of the change. int info provides additional
information of the
    change, e.g. platform specific error code.

  - NotifyAudioStreamVolume(int stream_id, double left, double right)
    Notify the current volume for the audio stream.
2. Added methods to RenderView for creating audio streams
and delegate audio related requests to browser process with
IPC. Now the registration and bookkeeping of
AudioRendererImpl happens in RenderView (see
audio_renderers_). The reason being that the code is almost
just an base::IDMap that doesn't worth creating a new class.
