* 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: add support for compressed audioEric Laurent2014-06-191-0/+9
| | | | | | | | | Add support for compressed audio playback by use of an AudioTrack attached to a direct output thread. Bug: 9428304. Change-Id: I4a61be9cf0e31003ca85935d6e0ee38ca8192e03
* 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

* | AudioTrack: When paused, return cached playback positionHaynes Mathew George2014-03-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | An offload output can be re-used between two audio tracks having the same configuration. A timestamp query for a paused track while the other is running would return an incorrect time. To fix this, cache the playback position on a pause() and return this time when requested until the track is resumed. Bug: 12826612. Change-Id: I324112ea9827e52fff53ef44cd8513c8d85a0bc4

* Refactor code related to I/O handles to reduce chance for leaksGlenn Kasten2014-01-241-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | The AudioRecord input handle code was refactored earlier to fix a potential handle leak, and to simplify the code: > Change-Id: I124dce344b1d11c2dd66ca5e2c9aec0c52c230e2 This changelist refactors AudioTrack similarly, and adds further cleanup of both AudioTrack and AudioRecord. We attempt to implement the rules for referencing counting I/O handles, but there is still the possibility of a handle leak if the client process dies after allocating the handle reference but before releasing it. That issue is being tracked separately. Details: - AudioSystem::getOutput() is now called within createTrack_l - restoreTrack_l was missing offload info now it has the info available, but is not yet being called for offloaded tracks - AudioTrack::getOutput() is now const - Remove getOutput_l() Change-Id: I44a0a623d24fc5847bcac0939c276400568adbca
