Just like the pcm_get_error() API, simplify the mixer API
functions to return pointers to constant strings instead
of making copies of strings.
|
|
Mark the write buffers as const - they won't be modified and this is
friendlier to applications.
|
|
Comment on buffer size was wrong. Argument to bytes_to_frames
is bytes, not frames
|
|
Add mmap playback and no period IRQ support to pcm core.
|
|
Add the ability to explicitly set start, stop and silence thresholds during
tinyalsa's pcm_open. Setting any of these values to 0 in your pcm_config
structure will cause the system to use its old defaults.
|
|
Add a extern "C" controlled by an #ifdef __cplusplus directive so that this
header can be included from C++ code without having to explicitly control the
linkage.
|
|
include: Add a local asound.h to allow build with current public releases
|
|
pcm_get_htimestamp() returns the number of available frames
in the kernel driver buffers as well as the corresponding
high resolution time stamp.
|
|
Bionic does not ship a copy of asound.h and it should do no harm to have
a local copy here.
|
|
This is essential for streams such as loopback devices that
do not transfer data.
