Ronald S. Bultje 7a9e65acee x86: lavr: fix stack allocation for 7 and 8 channel downmixing on x86-32 
Fixes crashes on Win32 and stack overruns on x86-32 in general.
 2012-11-17 20:16:04 -05:00
Justin Ruggles 02738792c5 lavr: fix the decision for writing directly to the output buffer 
If there are any samples remaining in the output fifo from previous conversion
calls, we have to output those samples first instead of doing direct output
of the current samples.

Diego Biurrun 2b479bcab0 build: Drop AVX assembly ifdefs 
An assembler able to cope with AVX instructions is now required.

Justin Ruggles a903f8f087 Include libavutil/channel_layout.h instead of libavutil/audioconvert.h 
Also reorder some other #include when applicable.

Diego Biurrun 352e18b766 x86: avresample: Add missing colons to assembly labels 
YASM accepts labels without colons, but NASM issues warnings.

Diego Biurrun 04581c8c77 x86: yasm: Use complete source path for macro helper %includes 
This is more consistent with the way we handle C #includes and
it simplifies the build system.

Diego Biurrun 6860b4081d x86: include x86inc.asm in x86util.asm 
This is necessary to allow refactoring some x86util macros with cpuflags.

Justin Ruggles 10e645e9cb lavr: handle clipping in the float to s32 conversion 
We cannot clip to INT_MAX because that value cannot be exactly
represented by a float value and ends up overflowing during conversion
anyway. We need to use a slightly smaller float value, which ends up
with slightly inaccurate results for samples which clip or nearly clip,
but it is close enough. Using doubles as intermediates in the conversion
would be more accurate, but it takes about twice as much time.

Anton Khirnov e7ba5b1de0 lavr: change the type of the data buffers to uint8_t**. 
This is more consistent with what the rest of Libav does.

This breaks API.

Diego Biurrun e0c6cce447 x86: Replace checks for CPU extensions and flags by convenience macros 
This separates code relying on inline from that relying on external
assembly and fixes instances where the coalesced check was incorrect.
