* Changed to use PushSource for the intermediate bufferhclam@chromium.org2009-06-052-0/+41
| | | | | | | | | | | | | | | between the IPC layer and the audio hardware interface. We have completely moved away from being blocking in AudioRendererHost. Since we'll be using PushSource for a longer period of buffering. It's necessary to have Play/Pause functionality in the AudioOutputStream, this is simulated by start/stop the AudioOutputStream multiple times.

| | | | | | | | | | The change actually supports arbitrary write size but write size greater than read size (packet size) is prohibited by an explicit check.

* Fix some threading issues and some refactoring in AudioRendererHosthclam@chromium.org2009-04-073-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
