* Remove obsolete base/lock.h and fix up callers to use the new header file andbrettw@chromium.org2011-01-211-2/+2
| | | | | | | | | | | the base namespace. Fix several files including lock.h unnecessarily. BUG=none TEST=none Original review=http://codereview.chromium.org/6142009/ Patch by leviw@chromium.org git-svn-id: svn://svn.chromium.org/chrome/trunk/src@72106 0039d316-1c4b-4281-b951-d872f2087c98
* Simplified AudioOutputStream interface.sergeyu@chromium.org2010-11-111-6/+1
| | | | | | | | | | | | | 1. Removed packet_size parameter from Open(). 2. Removed OnClose() from the callback. Now the callback is guaranteed to be called only between Start() and Stop(). 3. Added samples_per_packet in the AudioParameters struct. BUG=39825 TEST=Unittests Review URL: http://codereview.chromium.org/4661001 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@65766 0039d316-1c4b-4281-b951-d872f2087c98
* Add AudioBuffersState struct. Use it for audio synchronization.sergeyu@chromium.org2010-09-291-10/+9
| | | | | | | | | | | | | The new AudioBuffersState contains current state of the audio buffers. This object is passed all the way from the device to the audio renderer. Audio renderer uses this information to synchronize audio. BUG=52196,49110 TEST=see repro steps for 51637 and 52196.

* Make AudioOutputController.Close() truly asynchronous.sergeyu@chromium.org2010-09-171-7/+8
| | | | | | | | | | | | | Added closed_task parameter in this method. This parameter is used to notify the caller when the stream is actually closed. Callbacks may be called until closed_task is executed. BUG=55755 TEST=Unittests, audio still works, doesn't crash Review URL: http://codereview.chromium.org/3415007 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@59869 0039d316-1c4b-4281-b951-d872f2087c98

* Fixed crash in AudioOutputController.sergeyu@chromium.org2010-09-141-0/+4
| | | | | | | | | | | | AudioOutputController must not call EventHandler after it has been closed. Changing it so that lock_ is always locked whenever we call handler_ to ensure that state_ != kClosed.

* Rename a header and some methods to make way for subsequent audio recording ↵satish@chromium.org2010-07-121-1/+1
| | | | | | | | | | | | | additions. Renaming audio_output.h to audio_io.h as future patches will add audio recording code to this file. Also renamed a couple of methods to make it clear that these are for audio playback/output and similar methods will be added for audio capture/recording soon.

* Renamed AudioController to AudioOutputController.satish@chromium.org2010-07-091-0/+214
This is in preparation to add an AudioInputController for audio recording in subsequent changes. BUG=none TEST=no functional change Review URL: http://codereview.chromium.org/2964005 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@52015 0039d316-1c4b-4281-b951-d872f2087c98
