6d1622dc68 Move InitiatePositionArrays to mixer_defs.h 2014-06-06 07:15:22 -07:00

fc0be88c0f Add SSE2 and SSE4.1 linear resamplers 
Currently the only way SSE 4.1 is detected is by using __get_cpuid, i.e. with
GCC. Windows' IsProcessorFeaturePresent does not report SSE4.1 capabilities.

d2c0a43498 Add an ffmpeg-based example player 
This example shows proper timing and A/V synchronization with an OpenAL stream.
Requires the in-progress AL_SOFTX_source_length extension to avoid manually
keeping track of the buffer queue length.

933f51a8bf Only define struct timespec if _TIMESPEC_DEFINED isn't set 
This matches what the mingw-w64 headers define with the struct.

2d2bc25fd0 Add an extension string for the in-progress source length extension 
This is the extension that allows you to get the full length of the source's
buffer queue.

b6e1042e8c Implement condition variables (POSIX only!) 
Windows requires Vista or newer to get the CONDITION_VARIABNLE API, but we
currently only require XP.

fd5e7f1466 Don't print an ERR if pulse fails to get latency info due to no data 
It just means it was called too quickly after starting.

0ec0f7561c Add an option to get the length of a source's full queue 
This simplifies keeping track how much a source has buffered in its queue,
which reduces a bunch of unnecessary book keeping the app would have to do.

13eac2552e Update the examples to use SDL2 
This should make it easier to build the examples on 64-bit, where there are no
premade dev libs for SDL1 on 64-bit mingw. FindSDL_sound.cmake has been
updated to accept SDL or SDL2.

85e990e915 Don't try to use the non-standard alloca.h 
Variable-length arrays are C99 standard and are preferred over alloca. The only
compiler that needs alloca (MSVC) has it in malloc.h.

cd983245f1 Return a sample pointer from resamplers 
Both resampling and filtering now avoid copying samples when they no-op.

7b782f6afa Return a sample pointer from DoFilters 
This allows us to avoid copying samples when no filtering is needed. Doing the
same for resampling would require another temporary buffer in the device.

bd2721dc7a Use _mm_setr_ps instead of _mm_set_ps 
Apparently _mm_set_ps loads in reverse order compared to _mm_load_ps, so
_mm_setr_ps should give what we really want.
