* AAC encoder: fix wrong gain sacalefactor being setClaudio Freire2015-11-26
| | | | | | | | | In some conditions, where the first band was being zeroed mainly, the wrong global gain scalefactor would be written to the stream since it's always taken from the first band regardless of whether it's been marked as zero or not. So, always make sure it contians something useful.
* AAC encoder: Fix application of M/S with PNSClaudio Freire2015-11-26
| | | | | | | | When both M/S coding and PNS are enabled, scalefactors and coding books would be mistakenly clobbered when setting the M/S flag on PNS'd bands. The flag needs to be set to signal the generation of correlated noise, but the scalefactors, coefficients and the coding books need to be kept intact.

* avutil/libm: fix isnan compatibility hackGanesh Ajjanagadde2015-11-24
| | | | | | | | | | | | | Commit 14ea4151d7c3c26500193f11ac661ed20c7c2b9c had a bug in that the conversion of the uint64_t result to an int (the return signature) would lead to implementation defined behavior, and in this case simply returned 0 for NAN. A fix via AND'ing the result with 1 does the trick, simply by ensuring a 0 or 1 return value. Patch tested with FATE on x86-64, GNU/Linux by forcing the compatibility code via an ifdef hack suggested by Michael. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

* avfilter/vsrc_mandelbrot: change sin to sinf for color computationGanesh Ajjanagadde2015-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | lrintf is anyway used, suggesting we only care up to floating precision. Rurthermore, there is a compat hack in avutil/libm for this function, and it is used in avcodec/aacps_tablegen.h. This yields a non-negligible speedup.

* avfilter/vsrc_mandelbrot: avoid sqrt for epsilon calculationGanesh Ajjanagadde2015-11-24
| | | | | | | | | | | | | | | | | | | | | | | | | | This rewrites into a similar expression avoiding sqrt. Similarity is assured since sqrt(x^2 + y^2)/(x+y) lies in [1/sqrt(2), 1] for x, y > 0.

* | avcodec/ppc/fdctdsp: use M_SQRT2 instead of ad-hoc SQRT2Ganesh Ajjanagadde2015-11-22
| | | | | | | | | | | | | | | | | | | | | | | | | | This actually fixes an incorrect float literal. It is believed by examining the precision that the literals were all pre-computed as floats, resulting in this needless loss of precision. There is no benefit to keeping such reduced precision: 1. These constants are used for static array computation, hence compile-time. 2. They will be treated as doubles anyway, since f specifier was not present.
