* Description:annacc@chromium.org2011-05-161-2/+2
| | | | | | | | | | | | | | | | | This patch gets the channel layout for surround sound channel order from ffmpeg and stores it so that chromium will be able to re-order the channels for various sound cards and OSes later. - AudioParameters gets a new field (channel_layout). - channel_layout.h stores an enum that we will use in chromium for channel values. - ffmpeg_common.h gets a new method for mapping the channel layout received from ffmpeg to an internal chromium enum value. BUG=None (though storing the channel order should help us solve some other bugs soon) TEST=media_unittests Review URL: http://codereview.chromium.org/6930039 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@85541 0039d316-1c4b-4281-b951-d872f2087c98

* Cleaning up src/media to be consistent with static versus anonymous namespaces.scherkus@chromium.org2011-03-071-6/+2
| | | | | | | | | | | | | We were using a mix of both (and sometimes even static functions *inside* anonymous namespaces!) so we decided to stick to using static. Also moved static/test code into media namespace and removed media:: prefixes. BUG=none TEST=compiles Review URL: http://codereview.chromium.org/6628020 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@77135 0039d316-1c4b-4281-b951-d872f2087c98
* Simplified AudioOutputStream interface.sergeyu@chromium.org2010-11-111-4/+2
| | | | | | | | | | | | | 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.

* Add AudioBuffersState struct. Use it for audio synchronization.sergeyu@chromium.org2010-09-291-2/+3
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.

* Flush audio data after seekhclam@chromium.org2010-04-081-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is about 400 to 600 ms of audio that needs to be flushed after seek, this have a pretty UX effect. This is partially fixed in this patch by reducing the amount of data down to about at most 500 ms stored in the hardware buffer. This patch clears data in the software buffer in the browser process when seek happens. We could reduce the amount of hardware buffer to further reduce the amount of lag but that can be fixed by subsequent patch. BUG=24150 TEST=audio still works, audio still play after seek the playback of old data after seek is substantially reduced. Few changes in this patch: 1. Flush software buffer after seek in browser process 2. Get rid of prerolling, this actually has not effect at all, so getting rid of useless code Needs to be done after this patch: 1. Further reduce the remaining data after seek and pause 2. Still hit the DCHECK in ClockImpl::Play(), this doesn't seem to be a new problem introduced in this patch Review URL: http://codereview.chromium.org/1508021 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@43983 0039d316-1c4b-4281-b951-d872f2087c98
* Remove size_t from audio IPC code.jam@chromium.org2010-02-051-13/+13
| | | | | | | The change got to this size because I had to modify the surrounding code (I didn't want to just cast at the last minute). Review URL: http://codereview.chromium.org/577006 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@38192 0039d316-1c4b-4281-b951-d872f2087c98
* Providing unplayed bytes in audio hardware bufferhclam@chromium.org2009-08-241-1/+1
| | | | | | | | | | | | | | | | | BUG=20007 TEST=WinAudioTest.PCMWaveStreamPendingBytes We used to guess what is in the hardware audio buffer to perform audio sync. But due the triple buffering and other platforms has other buffering scheme we need to be able to know how many bytes are left in the hardware buffer. We provide this data via AudioCallback::OnMoreData(), so we can predict when the requested buffer will be played.

The change actually supports arbitrary write size but write size greater than read size (packet size) is prohibited by an explicit check. Review URL: http://codereview.chromium.org/118170 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@17686 0039d316-1c4b-4281-b951-d872f2087c98
