Camera: Fix deadlock due to mLock in pcb and takepicture

In non-zsl case of takepicture, we do streamoff for preview
stream which is waiting on preview callback thread to exit.
By that time the lock has already been acquired by takePicture.
So preivew callback will not exit until it acquires lock and
takePicture cannot continue until PCB call back is returned.

Fix: Avoid the mLock at services when both Preview cb &
Compressed cb are enabled.

audioflinger: Fix the LPA-AudioEffects crash issue
- Issue:crash is observed during LPA playback on enabling
  effects followed by plug-out->plug-in of wired headset
- Rootcause: while deleteing the effectchain in deleteEffect
  EffctChain is being unlocked after clearing the chain
  which leads to accessing the lock which might already deleted.
- Fix: first unlock the effectChain and then call clear

libstagefright: Fix for crash in sound recorder during device switch
-Crash seen in sound recorder during frequent insertion and removal
 of wired headset

-During device switch some time Codec's input buffers are too small to
 accomodate buffer read from source. Omx codec doesn't read the fix size
 buffer from source, during device switch scenario sometime buffer read
 from source exceeds input buffer size so it goes in error state which
 leads to crash.

-Increasing the input buffer size fix this issue

libstagefright: Fix for FPS drop issue during A-V playback.

Issues:
-The AAC decoder was not updating the timestamp when EOS is reached.
-Logic to smoothen the real time update in AudioPlayer uses system
 time. This introduces corrupt timestamp during EOS.

Fix:
-Update the timestamp in AAC decoder when EOS is reached.
-Extrapolate realtime using system time in AudioPlayer when EOS is
 reached. Cap the value to realtime if  extrapolated time becomes greater
 than realtime.

libstagefright: Reset buffer size value with SurfaceTexture

- OMXCodec explicitly sets the decoder output buffer size using the
  native window perform API. (to accomodate extra-data)
- This size is reset only when the SurfaceTexture is destroyed.
- Unless reset, this size will be assumed for all output buffers
  if the SurfaceTexture is re-used.

audio: Add support for non-pcm VOIP vocoders

- non-pcm vocoders use AUDIO_SOURCE_VOICE_COMMUNICATION
  as inputSource. Add check to verify inputSource and
  then configure framecount accordingly

frameworks/av: Add metadata mode changes to LPAPlayer

-Seek to EOS was causing playback to hang for 3 seconds before
 switching to the next clip.
-This is because the lpa driver works on period size. Partial
 buffers are not handled.
-Add support for metadata mode changes to LPAPlayer to support
 partial frames.

- WMA support is not there in ACodec
- In the case of wma format, since not getting the complete information of
wma version so instead of allocating the component in onAllocateComponent
function it will create in onConfigureCompoenent function.
bitspersample is find as "bsps" from AMessage while configuring the

the aac config frame buffer to update the sample rate and channel
mode and flush out the buffer.

media, audioflinger: check for divide by zero possibilities and err

When output stream is not available to audioflinger due to any reason
, sampleRate and frameCount have zero values when trying to create
new Audiotrack. This might result in divide by 0 situation.

framewroks/av:Fix ANR at the end of video recording

- While doing video recording, when the recording
  ends ANR observed while doing stress test for
  many hours
- When the recording is stopped, audio HAL receives error
  from driver and  audio HAL propagates this error to
  AudioFlinger.  But AudioFlinger  is not sending error
  status to audio source to stop recording.  Because of
  this audiorecord thread keeps on waiting for buffers
  which is resulting in ANR.
- To avoid indefinite wait, a timeout of 1 sec is set for buffer
  in audioSource and after timeout, -ETIMEDOUT is returned
  to recorder thread.

audioflinger: Integrate SRS TruMedia

Change-Id: If61ae91556120ddd5f5ebcc6dbbfe6583c7df67d

audioflinger: Fix apply SRS effects if tones diabled in tunnel mode

For the use case of SRS post processing in Tunnel mode, the API's
of SRS are called only from write. With the huge buffering for
tunnel mode, once EOS is received there would not be further write.
With system tone enabled, the SRS API's are called during the
check for Parameters change through normal mixer thread.
With system tones disabled, SRS will not be applied after EOS as
no write and mixer thread would not be active.

Fix the issue by adding the Effects Thread for SRS in Tunnel mode.
Fix the compilation issue with ALOGV messages enabled

audioflinger: Enhance LPA-effect logic to handle rapid config.

-Issue:Rapid Config events cause pops/glitches, raw data
 playback.
-Rootcause1:Raw data leakage to DSP: applyEffectsOn() applies
 effects chunk by chunk in a loop, if effects change during
 this time the loop exits and this results in creation of
 a buffer in which part of it is effects processed and rest
 raw, this causes raw data to leak to DSP.
-RootCause2:Effectsthread directly works on the DSP buffers,
 while DSP is rendering from there, so that effect application
 is instantaneous and for this it gives the DSP buffers as
 output to effects chain, this means that all the effects in
 the chain update the DSP buffers one after the other, this
 can create unpredictable rendering patterns.
 RootCause1 and 2 combined seem to fragment memory with
 parts of it with effects and parts with raw data etc.
-Fix1:Dont update DSP mem unless the effects are applied
 completely on a buffer.
-Fix2:Effectschain will work on a temp scrath buffer
 instead of DSP mem and when effects are applied
 completely on this scrath buffer, memcpy this to DSP mem
 with this DSP mem is updated in one shot.
-Remove repetetive logs which clutter the logcat if
 msgs are enabled in audioflinger.

audioflinger: Fix the LPA-AudioEffects dead lock issue.

- Issue:Deadlock occurs when the LPA clips are subjected to
  rapid next from BT device and simultaneously on/off the
  audio effects.
- Rootcause:some times flinger thread processing
  LPAPlayer/directtrack next deadlocks with the thread
  working on effect configuration as both of them
  contend for the audioflinger::mlock and effectmodule::mlock.
- Fix1:AudioFlinger::deleteEffectSession() not to acquire
  audioflinger:mLock  instead take the mLPAEffectChain.mlock.
- Fix2:ThreadBase::effectConfigChanged() not to acquire
  audioflinger::mlock.

libstagefright: Move checks for creating new extractor to ExtendedExtractor

- Move all the checks and creation of the extended extractor
  into ExtendedExtractor.
- Restrict creation of new extractor to the following conditions
	o default extractor is NULL
	o default extractor says the content is video only
	  or has an unrecognized audio stream
	o the audio stream is a amr-wb (plus).
- This change is being added to avoid unnecessary creation of
  two extractors thereby improving the startup latency.

[StageFright] Enable 4 channel support

This patches enables 4 channel WAV audio support and fixes invalid
data size in WAV header field if it exceeds the actual source size.
