Fast, reasonably accurate 10^x. Alternative of detection of libm exp10 at configure time is not worth the trouble, since it is anyway not POSIX or ISO C, and currently only the GNU libm has it. Furthermore, GNU libm's variant is ~ 2x slower, and is ironically not correctly rounded (2 ulp off) to justify all that slowdown.

So far an AC-3 elementary stream is refered to in the PMT according to System A (ATSC). An E-AC-3 ES in contrast is embedded the System B (DVB) way. To fix this inconsistency, this commit changes the default E-AC-3 behaviour to use the ATSC way, too. Furthermore a new flag is added to optionally select the DVB way (regarding both codecs and possible further differences in the future). Signed-off-by: NMichael Niedermayer <michael@niedermayer.cc>

exp10 is a function available in GNU libm. Looks like no other common libm has it. This adds support for it to FFmpeg. There are essentially 2 ways of handling the fallback: 1. Using pow(10, x) 2. Using exp2(M_LOG2_10 * x). First one represents a Pareto improvement, with no speed or accuracy regression anywhere, but speed improvement limited to GNU libm. Second one represents a slight accuracy loss (relative error ~ 1e-13) for non GNU libm. Speedup of > 2x is obtained on non GNU libm platforms, ~30% on GNU libm. These are "average case numbers", another benefit is the lack of triggering of the well-known terrible worst case paths through pow. Based on reviews, second one chosen. Comment added accordingly.

complex is not available on all platforms. Furthermore, it is trivial to rewrite complex number expressions to real arithmetic, and in fact sometimes advantageous for performance reasons: by wrapping as a complex, one forces a particular Cartesian representation that is not necessarily optimal for the purpose. Configure dependencies also removed, and aemphasis is now available across all platforms. Reviewed-by: NPaul B Mahol <onemda@gmail.com> Signed-off-by: NGanesh Ajjanagadde <gajjanagadde@gmail.com>
