swscale/ppc/swscale_altivec.c: POWER LE support in yuv2planeX_8() delete macro GET_VF() it was wrong GCC tool had a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by reading the related info on GCC website. We fix our previous error in two separate commits Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

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. Signed-off-by: Mans Rullgard <mans@mansr.com>

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. Signed-off-by: Mans Rullgard <mans@mansr.com>

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.

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.

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.

This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).

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.

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.
