* | avcodec/simple_idct: use predefined M_SQRT2Ganesh Ajjanagadde2015-11-141-2/+2
| | | | | | | | | | | | | | | | | | | | M_SQRT2 is defined in math.h, or in avutil/mathematics.h for compatibility hacks. This uses this value instead of a floating literal. Fixed point values produced by C_FIX(), R_FIX() remain identical. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* | avcodec/simple_idct10: improve precisionChristophe Gisquet2015-10-131-2/+7
| | | | | | | | | | | | | | | | | | | | | | omse goes from 0.03060703 (which fails for dct-test) to 0.01663750. This also actually improve the error of decoding the sample generated by fate-vsynth3-dnxhd1080i-10bit using simple_idct10 to FAANI, which goes (when resampled to yuv422p) from: stddev: 0.06 PSNR: 72.28 MAXDIFF: 1 to identical.

* Convert asm keyword into __asm__.Diego Pettenò2008-10-161-2/+2
| | | | | | | | | | | | | Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax.
