* | Enable new dynamic audio resampler as defaultAndy Hung2014-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The default may still be overridden by af.resampler.quality in the local or build properties file. For the build properties check the relevant device.mk files. In the absence of being overridden, the 44.1 to 48kHz and 48 to 44.1kHz conversion will use the DYN_MED_QUALITY resamplers and other conversion will use the DYN_LOW_QUALITY resamplers.

| * AudioMixer: Remove tracks from enabledTracks after reseting outTempGaurav Kumar2014-01-291-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If any track goes through AudioMixer::process__genericNoResampling, and its getnextbuffer returns NULL, Then that track is removed by AudioMixer from enabledTracks. Thus if all tracks getnextbuffer return NULL, Then this function doesn't reset outTemp and last buffer in AudioFlinger's mMixBuffer will be repeated and noise is observed. Remove tracks from enabledTracks after reseting outTemp to zero, so that process__genericNoResampling will reset outTemp and noise won't appear.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code that initializes downmix GUID searches for an effect of the right type. If two or more AudioMixers are created, there is a possibility that the GUID will temporarily have the wrong value. Now the initialization is only done once, regardless of how many AudioMixers there are. Other minor changes: - use naming convention of leading 's' for static member variables - log message for no downmix effect is now a warning instead of an error, since it is not an error until there is actual content to downmix without a downmix effect Change-Id: I33ab0e51cf9d24ecaf8ae868883736b0772178c4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Very high quality is enabled only for 44.1 -> 48 or 48 -> 44.1, and uses low quality for all other use cases. Track estimated CPU load and throttles the quality based on load; as currently configured it should allow up to 2 instances of very high quality. Medium quality and high quality are currently disabled unless explicitly requested. Details: Only load .so the first time it is needed. Cleanup code style: formatting, indentation, whitespace. Restore medium quality resampler, but it is not used (see next line). Fix memory leak for sinc resampler. Check sample rate in resampler constructor. Add logs for debugging. Rename DEFAULT to DEFAULT_QUALITY for consistency with other quality levels. Renumber VERY_HIGH_QUALITY from 255 to 4. Use enum src_quality consistently. Improve parsing of property af.resampler.quality. Fix reentrancy bug - allow an instance of high quality and an instance of very high quality to both be active concurrently.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value 1 << 32 (maxNumTracks defaults to 32) is surprisingly not defined in C, and differs on MIPS than the other arch. Therefore the track resources were not initialized properly, resulting in failure to play any audio. The fix allows the mConfiguredNames bitmask to be correctly set to all 1's in the 32-track case, for all arch.

* Fix multichannel downmix pause bug on video playerJean-Michel Trivi2012-04-181-20/+51
| | | | | | | | | | | | | | | | | | | | | | Pausing a video player will cause the track audio mixer to be disabled, which causes the downmixer to be deleted. When reenabled, the track channel mask hasn't changed but the downmixer is there anymore. Fixed by: - instanciating a downmixer when the AudioMixer track gets initialized (in getTrackName(), now taking a channel mask as input), and deleted when in deleteTrackName(). - when the channel changes on a track, check whether it needs a downmixer or not. Preparing a track for downmix automatically removes the old downmixer if there was one. Also: initialize the track downmixerBufferProvider field when AudioMixer is instanciated, so we can safely call delete on it in AudioMixer's destructor, in case deleteTrackName() wasn't called before the mixer was destroyed.

* Configure the resampler with the correct channel count when downmixingJean-Michel Trivi2012-04-181-2/+5
| | | | | | | | | | | | | When a track needs to be downmixed and resampled, it gets downmixed first before being resampled. Therefore the resampler needs to be configured with the channel count of the output of the downmixer instead of that of the track. Removed frame size checks that don't apply anymore now that we support frame sizes that are not powers of 2 (e.g. 12 for 5.1 16bits), and changed test performed for every buffer during playback into an assert.

* AudioMixer uses downmix effect for multichannel contentJean-Michel Trivi2012-04-091-4/+217
| | | | | | | | | | | | | | In the AudioMixer structure associated with each track, add an object that acts as the buffer provider when the track has more than two channels of input in the mixer. This object, DownmixerBufferProvider, gets audio from the actual buffer provider of the track, and applies a downmix effect on it. The downmix effect is created and configured when the track gets created in AudioFlinger, which causes AudioMixer::getTrackName() to be called with the new track's channel mask. It is released when the track is disabled in the mixer. Change-Id: I05281ed5f61bef663a8af7ca7d5ceac3517c82db
