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: Michael 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: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

Fixes a specific srt sample, which has an event with negative duration. libavcodec will convert an event with negative duration to an ASS event which will be displayed forever, which is not wanted here. Treat negative duration always as unknown duration instead, and show it until the next subtitle event.

A negative bits_per_coded_sample doesn't make sense. If it is too large, the size calculation for av_get_packet overflows, resulting in allocation of a too small buffer. Also make sure width and height are sane. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

Instead of calling the input filter request_frame() method, ff_request_frame() now marks the link and returns immediately. buffersink is changed to activate the marked filters until a frame is obtained.

The status field can carry any error code instead of just EOF. Also only update it through a wrapper function and provide a timestamp. Update the few filters that used it directly.

Applications are not supposed to mess with links, they should close the sinks. Furthermore, this function does not distinguish what end of the link caused the close and does not have a timestamp.

This field is used for fast comparison between link ages, it is in AV_TIME_BASE units, in other words microseconds, µs =~ us. Renaming it allows a second field in link time base units.
