Mans Rullgard 07eb7e20af ppc: swscale: rework yuv2planeX_altivec() 
This gets rid of the variable-length scratch buffer by filtering 16
pixels at a time and writing directly to the destination.  The extra
loads this requires to load the source values are compensated by not
doing a round-trip to memory before shifting.

Mans Rullgard d853e571ad ppc: fix some pointer to integer casts 
Use uintptr_t instead of plain int.  Without this change, the
comparisons will come out wrong for pointers in certain ranges.
Fixes random failures on ppc64.  Also fixes some compiler warnings.

Ronald S. Bultje 3f04ab4fcd swscale: split hScale() function pointer into h[cy]Scale(). 
This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.

Luca Barbato 3304a1e69a swscale: add dithering to yuv2yuvX_altivec_real 
It just does that part in scalar form, I doubt using a vector store
over 2 array would speed it up particularly.

The function should be written to not use a scratch buffer.

Ronald S. Bultje 28c1115a91 swscale: use 15-bit intermediates for 9/10-bit scaling. 2011-08-12 11:54:25 -07:00
Ronald S. Bultje 8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth. 
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

Ronald S. Bultje ef1ee362b3 swscale: implement >8bit scaling support. 
This means that precision is retained when scaling between sample
formats with >8 bits per component (48bit RGB, 16bit grayscale,
9/10/16bit YUV).

Ronald S. Bultje 13a099799e swscale: change prototypes of scaled YUV output functions. 
Remove unused variables "flags" and "dstFormat" in yuv2packed1,
merge source rows per plane for yuv2packed[12], and make every
source argument int16_t (some where invalidly set to uint16_t).
This prevents stack pollution and is part of the Great Evil Plan
to simplify swscale.

Ronald S. Bultje dc179ec819 swscale: split yuv2packedX_altivec in smaller functions. 
This will likely lead to a considerable performance boost,
since it removes a branch from the inner loop. Part of the
Great Evil Plan to simplify swscale.

Ronald S. Bultje 76f8a96e00 [PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats. 
Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
if no altivec-optimized version exists.

Ronald S. Bultje c8f487deae swscale: fix YUV420P 9/10bit support. 
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

Luca Barbato 86330b4c92 swscale: partially move the arch specific code left 
PPC and x86 code is split off from swscale_template.c. Lots of code is
still duplicated and should be removed later.

Again uniformize the init system to be more similar to the dsputil one.

Unset h*scale_fast in the x86 init in order to make the output
consistent with the previous status. Thanks to Josh for spotting it.
