* nuplayer: Enable PCM offload for any sourceSteve Kondik2015-12-291-1/+1
| | | | | | | | | * Use the raw PCM format to perform the early open of the audio sink. This ensures that the renderer will do the same. * Fill in stubs for timestamp and position calculation. This fixes underruns and other issues. Change-Id: I8d761e523194cc12f387b4b2aa1594536e56da01
* AudioTrack: Handle timestamp queries for Track OffloadAlexy Joseph2015-11-151-0/+1

* libmedia : audio: handle set playback rate when direct pcm usedvivek mehta2015-10-241-0/+1
| | | | | | | | | - In direct PCM usecase if setplayback rate is called then invalidate the common block and send empty offload structure below to use default path. CRs-Fixed: 916660 Change-Id: I6df7c10b7115c77a19564e2f9fabc511d76a2410

* Improve AudioTrack offload timestamp startup glitch detectorAndy Hung2015-06-041-0/+1
| | | | | | | | | | | | | New or existing glitch behavior for Nexus 5 offload audio: we receive several 0 timestamps, then we get a stale timestamp (very large), then a few ms later we get a correct nonzero timestamp. We attempt to hide the glitch because the retrograde timestamp correction makes the glitch "sticky". Bug: 21633313 Change-Id: I39153af718c151f9435e7d315651a811f72743da
* Compute sleep time when AudioTrack client callback returns no PCM dataAndy Hung2015-06-031-6/+14
| | | | | | | | | | | | Callbacks can go into a sleep-wait cycle if the client/app is unable to deliver data. This can happen if the buffer is large, or if the client/app cannot keep the buffer filled, or upon a stream end condition. We improve the sleep time computation for AudioTrack PCM callbacks. This minimizes the number of callbacks to NuPlayerRenderer. Bug: 21198655 Change-Id: I4247798a6638def2f0d8f1b46f60323482065cb2

* Implement audio device callbackEric Laurent2015-05-061-1/+34
| | | | | | | | | | | | | | | | | | | | Add class AudioSystem::AudioDeviceCallback notifying AudioSystem clients upon device selection change on a given input or output thread. Maintain a list of installed callback per I/O handle in AudioSystem and call registered callbacks when an OPEN of CONFIG_CHANGED event is received on IAudioFlingerClient::ioConfigChanged(). Add methods to AudioTrack and AudioRecord to add and remove device change callbacks. Add methods to AudioTrack and AudioRecord to query currently selected device. ioConfigChanged() events now convey the audio patch describing the input or output thread routing. Fix AudioRecord failure to start when invalidation is handled by start(). Change-Id: I9e938adf025fa712337c63b1e02a8c18f2a20d39

* AudioTrack: fix spurious retrograde messagesPhil Burk2015-04-291-0/+3
| | | | | | | | | | | The retrograde motion was confused by some positions coming from the DSP on offloaded tracks. So the retrograde check was moved up into AudioTrack.cpp. This allows us to take advantage of the checks for invalid positions based on timing.

* Allow AUDIO_FORMAT_PCM_8_BIT AudioTrack buffersAndy Hung2015-01-141-11/+5
| | | | | | | | Previously conversion to AUDIO_FORMAT_PCM_16_BIT was required. Client shared memory for static tracks and AudioFlinger track creation and buffer delivery now use native 8 bit PCM data. Change-Id: I485c07a4971fde9a25442bd43fed95019d39abcc

* audio policy: new getOutputForAttr() prototype.Eric Laurent2014-11-251-5/+6
| | | | | | | | | | | | | | | | | | | | | | | Update getOutputForAttr() prototype and group all logic dealing with audio attributes to stream type conversion in audio policy manager. getOutputForAttr(): - specifies the audio session (for future use) - returns a status code - receives either stream type (for legacy) or audio attributes - returns an updated streamtype Remove logic dealing with legacy stream types to attributes conversion from AudioTrack. Use correct type for audio sessions in other APIs (startOutput() ...). releaseOutput() specifies the audio session (for future use). Bug: 18067208.

* Fix AudioTrack offloaded timestamp handling.Andy Hung2014-09-171-1/+10
| | | | | | | | | | getTimestamp for offloaded tracks now returns WOULD_BLOCK for situations where the timestamp is unavailable due to the previous track still flushing or the timestamp is stale. It is fixed for normal playback conditions. Bug: 14659809 Bug: 17428188 Change-Id: Ic9ec07ccabc604236979769db5c4ea2dec252660
* Clean up AudioTrack position and timestamp handlingGlenn Kasten2014-09-111-2/+18
| | | | | | | | | | | | | | | | | | | Replace epoch concept by observing and accumulating server delta positions. The advantage of using server deltas instead of absolute values is that they (1) are not sensitive to 32-bit wraparound, (2) are not sensitive to server behavior for stop(), and (3) prepare for future 64-bit client positions without requiring 64-bit positions on server. Add comments to AudioTrack::getTimestamp() and friends that the timestamp output parameter is undefined on error. Don't allow getTimestamp to return a negative frame position after stop(). Accumulate the client released frames, which may be useful for a future API. Bug: 11815245 Change-Id: I652940fa2db2f34a78c012a3ead0d9204fa29c6e

* AudioTrack construction with audio attributesJean-Michel Trivi2014-06-171-1/+8
| | | | | | | | | | | | Store audio attributes in AudioTrack class. When an AudioTrack is "set" with non null audio attributes, derive a stream type that reflects the attributes. When an AudioTrack is "set" without attributes, and only has a stream type, derive default audio attributes. Change-Id: I322b91fa9a7e193118960c5e78cdddd85d66f9ad
* Add client side support for more AUDIO_FORMAT_PCM_*Glenn Kasten2014-05-071-2/+3
| | | | | | | As much as possible, the checks for specific formats are done on server side. The only exception is 8-bit, which needs a client side workaround. Change-Id: I52fe086c039460c8dac009de03b67eb54c56a836
