Sebastian Dröge 9e4f1e7346 opensles: Fix compilation with debugging enabled 2012-11-02 11:25:21 +01:00
Sebastian Dröge 1f6944efc1 opensles: Remove unused variable 2012-11-01 15:38:32 +01:00
Sebastian Dröge 40ca6ed977 opensles: Make sure to only ever create a single engine object 
The OpenSL ES spec defines:

An implementation shall enable creation of at least one such object, but
attempting to create more instances (either by a single application or by
several different applications) may fail.

Josep Torra 1d9f48a33d opensles: drop 48kHz sample rate 
OpenSL ES implementation in Android is just a 'facade' API on top of
AudioFlinger which will downsample 48kHz into 44.1kHz before
delivering the audio to the underlaying hardware.

We found that it suffer some sort of underrun when the downsample
enters in action so relay on our good resampler to take care of that
and fix the clicks issue. And get an extra bonus of a lower latency.

Josep Torra 9cc7e6a74d opensles: change the defaults to use 20 ms ringbuffer segments 
In my nexus7 seems that the internal min buffer size is 20 ms so make
our segments match.

Josep Torra 97a1ccfab1 opensles: ensure that we register the callback only in STOPPED 
Fixes the error registering the callback on the PLAYING -> PAUSE ->
PLAYING state change sequence.

Josep Torra e265cec514 opensles: cap queue size 
Just in case we want to tweak the sink behaviour with buffer-time and
latency-time properties cap the queue size to something reasonable.

Josep Torra cc6fc15674 opensles: sink to provide the audioclock by default 2012-10-18 14:03:09 +02:00
Josep Torra 08ef2e3eed opensles: only drain half ringbuffer on start 
At start drain half ringbuffer into the OpenSL so the writting/reading
pointers will start at half ringbuffer distance.

Josep Torra 9fcfa00680 opensles: refactor to behave more like other sinks 
Reflect the queue in our own data buffer.
Drop the _commit hook that wasn't usefull.
Don't mess with the segsize/segtotal.

Josep Torra f06688c7b2 opensles: make the volume property actually work 2012-10-18 14:03:08 +02:00
Josep Torra 0291953997 opensles: rework on the ringbufffer to properly clear segments 
Make the segments bigger (1 second) as it seems to be the minimum size
we need to not introduce noise.
Sink works in my nexus 7 with rates from 8000 to 44100 and some noise
can be noticed on higger sample rates.

Josep Torra 29334f3233 opensles: fixes the license headers 2012-10-18 14:03:08 +02:00
Josep Torra 805a010dc9 opensles: produces expected output until ringbuffer wraps 
Add some log messages.
Fixed a bit the _player_cb function and properly advance reding in the
ringbuffer.
Still produces noise when the ringbuffer wraps.
