* Fixed AudioFlinger not always pausing tracksEric Laurent2010-10-051-3/+3
| | | | | | | | | | | If the pause request is received before the AudioTrack buffer was completelly filled and the track ready for mixing, the pause is not executed: the track just underruns and stays in pausing state. The fix consists in considering the track ready for mixing immediately if pausing. Change-Id: Ia6cb4703fee2126e41011a6400ea8eeb3a3e5456
* Issue 3032913: improve AudioTrack recovery timeEric Laurent2010-09-301-4/+13
| | | | | | | | | | | | This issue showed that when an AudioTrack underruns during a too long period of time and is therefore disabled by audioflinger mixer, it takes an additional delay of up to 3 seconds to recover. This fix adds a simple mechanism to recover immediately when the client application is ready to write data again in the AudioTrack buffer Also throttle warnings on record overflows Change-Id: I8b2c71578dd134b9e60a15ee4d91b70f3799cb3d
* Fix several audio effects problems.Eric Laurent2010-09-281-8/+32
| | | | | | | | | | | | | | | Fixed the following issues in LVM effect bundle wrapper: - memory leaks in EffectCreate() in case effect creation fails at various stages - Added saturation when accumulating to output buffer - Fixed problems with enabled effects count when an effect is released while enabled - Do not allocate temporary buffer for accumulation each time process() is called Fixed the following issues in effects framework (AudioFlinger) - Release effect synchronously in the library when deleted from effect chain - Do not call the effect process function if no tracks are present in the same audio session Change-Id: Ifbd80a163415cfb3c0a337c12082853ea45d9c91
* The old overlay should be destroyed if orientation changes.Wu-cheng Li2010-09-272-6/+16
| | | | | | | | | | | | | Previously the orientation was wrong after suspend and resume. When the camera app is resumed behide the lock screen, it orinteation is portrait. When users slide to unlock the screen, surfaceChanged is called and the orientation is landscape. The camera app stops the preview, sets the display orientation, and starts the preview. Overlay should be destroyed if the orientation has changed. bug:3031640 Change-Id: I38b527f9ea78c91b538463292152c023383b4695
* Fix issue 3007862Eric Laurent2010-09-241-40/+49
| | | | | | | | | | | | | | | | Removed a cross deadlock condition between audioflinger and audio policy service mutexes. Audioflinger::createEffect() locks audioflinger mutex and then calls AudioSystem::getOutputForEffect() which ends up in AudioPolicyService::getOutputForEffect() which locks audio policy service mutex. If at the same time, the command thread in audio policy service is processing a command(set volume, set route...), the mutex is locked and the command will call one audioflinger method which in turn will attempt to lock audioflinger mutex. The fix consists in releasing audioflinger mutex before calling getOutputForEffect(). Change-Id: Id44e7feb36e0a295731f6aa97cf32d022edd34d0
* Request permission for global audio effects.Eric Laurent2010-09-221-14/+18
| | | | | | | Applications creating an audio effect on the output mix must have the MODIFY_AUDIO_SETTINGS permission. Change-Id: I57d88533f91ad0d33680107d79abcec28f7263b5
* Fix volume problems with insert revertEric Laurent2010-09-131-29/+31
| | | | | | | | | | | | | | | | | - Use a constant input level to the reverb engine and implement volume control in the insert reverb. This avoids the volume spikes when an effect that was inserted after the reverb is disabled or removed. - Fix clicks (one silent buffer) at the end of the reverb disable period. - Modified volume management in audioflinger so that the volume ramp is also done by the insert effect if present when the track is paused (avoids clicks). - Increased room level for all presets. Also fixed problems with output stage session (-1): - effect bundle wrapper was not designed to support session -1 - the permission check in audioflinger for using session -1 failed due to a wrong usage of getCallingPid() Change-Id: Id1ff51327263364bf71d3f2668fa5cde4311d84f
* Fix problem in AudioEffect::command() status.Eric Laurent2010-09-021-5/+9
| | | | | | | The *pReplyData argument of the command() function was left unitialized by EffectHandle::command() when command was EFFECT_CMD_ENABLE, EFFECT_CMD_DISABLE and EFFECT_CMD_SET_PARAM_COMMIT. Change-Id: I91a19817ead2a8cfbdd8e2d77ca270c7ce9d5bd4
* Audio Effects: fix problems in volume control.Eric Laurent2010-08-312-7/+32
| | | | | | | | | | | | | - Fixed click when re-enabling effect during the turn off phase: make sure the effect states where effect is processed are the same where volume control is delegated to effect. - Fixed click when effect is deleted while still active: do not apply volume ramp if an effect having volume control was just removed from the effect chain. Also fixed a crash when PCM dump is enabled in effect bundle wrapper. Change-Id: Ib562f5cf75c69af75df0e862536262e2514493e4
* Fix issue 2952766.Eric Laurent2010-08-271-18/+24
| | | | | | | | | | | | The problem is that the audio policy manager does not handle the input devices when forced use for telephony is changed. The problem does not appear in a call over PSTN becasue only teh output devices drives the routing of in call audio to/from the base band. The fix consists in modifying AudioPolicyManagerBase::setForceUse() to check for active inputs and update the input device if needed. Change-Id: I0d36d1f5eef1cce527929180c29b025439902f10

| | | | | | | | Fixed regression introduced by change a54d7d3d7dd691334189aab20d23c65710092869 in audioflinger mixer thread: When the output stream is suspended, the sleep time between two writes must match the actual duration of one output stream buffer otherwise the playback rate is not respected.

* Fixed underrun in audioflinger mixer.Eric Laurent2010-07-291-2/+2
| | | | | | | | | | | | | When all audio tracks have been disabled and the mixer is running idle before the output stream is placed in standby, the mixer sometimes fails to write to the output stream on time to avoid underrun. This is because the sleep period used to wait before the next write to output stream is too close to the actual buffer duration. In fact this sleep time is not critical as if we write too early to the output stream, the kernel driver will wait for free buffers from the audio DSP DMA and we will sleep anyways. The fix consists in dividing the calculated wait period by 2 to increase the margin. Change-Id: I5730887dc2ccce2a511bc858494a6f7da6b392a0
* Allow creation of an audio effect on a session with no audio tracks.Eric Laurent2010-07-292-16/+72
| | | | | | | | This is necessary to allow creating and enabling an effect attached to a particular player session before the playback is started. As a matter of fact, the implementation of the mediaplayer does not create the AudioTrack before playback starts. Change-Id: I1266e8885f9d756acc949303321aaac0fbf83e34
* Audio effects: modified command() parameter types.Eric Laurent2010-07-282-26/+97
| | | | | | | The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command() function have been modified from int to uint32_t. This is more consistent with their role. Change-Id: I84d289fc262d6753747910f06f485597dfee6591
* Audio policy manager changes for audio effectsEric Laurent2010-07-205-200/+652
| | | | | | | | | | | | | | | Added methods for audio effects management by audio policy manager. - control of total CPU load and memory used by effect engines - selection of output stream for global effects - added audio session id in parameter list for startOutput() and stopOutput(). this is not used in default audio policy manager implementation. Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring effect engines from one output mixer thread to another when audio tracks in the same session are moved or when requested by audio policy manager. Also fixed mutex deadlock problem with effect chains locks. Change-Id: Ida43484b06e9b890d6b9e53c13958d042720ebdb
* Fixed problems in audio effect volume control.Eric Laurent2010-07-192-10/+24
| | | | | | | | | | Fixed the following problems in audio effect volume control in AudioFlinger: - Make sure that the volumes returned by EffectChain::setVolume_l() are correct even is no change is detected since last call - Do not use isEnabled() to validate volume control but mState >= ACTIVE instead as the volume control must be also active in STOPPING and STOPPED states. Change-Id: Id62da3164fad500ee8a5efd6cd78c77e8fdcb541
* Several improvements in audio effects volume control.Eric Laurent2010-07-152-70/+73
| | | | | | | | | | - Fixed crash when deleting an effect chained before an effect having volume control - Changed EFFECT_FLAG_VOLUME_CTRL to implicitely include EFFECT_FLAG_VOLUME_IND (not need to set both in effect descriptor). - Volume control changes from one effect to another if needed according to effect enable state - EFFECT_CMD_SET_VOLUME is only sent when their is an actual change in volume Change-Id: Ieebaf09157e2627366023569d95516646e03e26c
