* Fix muted audio when playback rate != 1.0 or 0.0vrk@chromium.org2012-03-061-21/+32
| | | | | | | | | | | | | | Rewrites the logic in AudioRendererAlgorithmBase to be able to output audio at any point of a sped-up/slowed down window, instead of only outputting audio in full multiples of windows. BUG=108239 TEST=media_unittests, manual testing on video test matrix Review URL: http://codereview.chromium.org/9395057 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@125052 0039d316-1c4b-4281-b951-d872f2087c98
* buffers.cc: replaced global TimeDelta constants with fully-inlined functions.fischman@chromium.org2012-01-181-3/+3

* Add AudioBuffersState struct. Use it for audio synchronization.sergeyu@chromium.org2010-09-291-4/+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.

| | | | | | | | | | TEST=SeekableBufferTest.* Updating media::SeekableBuffer and unit tests to meet code style standards. Review URL: http://codereview.chromium.org/114042 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@17084 0039d316-1c4b-4281-b951-d872f2087c98
* SeekableBuffer to implement a window of buffer which has short seeking ability.hclam@chromium.org2009-05-191-0/+192
Defined the base interface SeekableBuffer and a thread safe implemntation of ThreadSafeSeekableBuffer. This class is to be used for media resource loading that does the meat of buffer queueing and handles short seeking for short distance out-of-order read patterns.
