* Fix some threading issues and some refactoring in AudioRendererHosthclam@chromium.org2009-04-076-8/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. AudioRendererHost should not wait on IO thread. Calling AudioOutputStream::Start requests some audio packets by calling IPCAudioSource::OnMoreData, resulting in a deadlock. I implemented a prefetching logic to solve this problem, source has to know how many internal buffers the implementation of AudioOutputStream is using and prepare the same amount of packets before calling AudioOutputStream::Start. 2. When IPCAudioSource::OnMoreData is waiting for packet to arrive, calling AudioOutputStream::Stop will result in a deadlock since it expects OnMoreData to return. Should wake up all waiting threads before calling AudioOutputStream::Stop. 3. Did some refactoring and move the message handlers completely into AudioRendererHost, it was clumsy to call to AudioRendererHost from ResourceMessageFilter. Also moved all logics of using shared memory for packet passing, prefetching to IPCAudioSource. AudioRendererHost is now merely a container that manages and delegates calls to IPCAudioSource. This refactoring is helpful because the next step is to implement standalone IPC channel for audio.

* Audio related IPC messages and handlers from browser tohclam@chromium.org2009-02-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
