Changing the volume when softvol is enabled or if the audio output driver
doesn't support volume controls causes insertion of the "volume" filter.
This fails with AC3. Since the filter wasn't removed after that, and the
filter chain was in a bogus state, random crashes occured past this
point.
Fix it by reinitializing the filter chain completely on failure. Volume
controls simply won't work. (This can't be fixed, because AC3 is a
compressed format, and would require additional decoding/encoding passes
in order to support arbitrary volume changes.)
This also affects balance controls.
When -channels 2 [default] is specified and the audio decoder used
does not support internal downmixing, automatically add a pan filter
after the decoder to downmix to stereo.

Enable all of libavcodec, libavformat, libswscale, and libpostproc
together (libavutil is always required).

Call this function also from af_add, fixes audio corruption with e.g.
-softvol -af format=s16be (bug #1561).

Add configure option --ffmpeg-source-dir=PATH. If the user specifies
this option then building code that depends on FFmpeg internals is
enabled and the files files which use internal lavf headers will get
them from this path. The FFmpeg libraries linked with must export
needed internal symbols.
Replace all USE_ prefixes by CONFIG_ prefixes to indicate
options which are configurable.

And if set first parameter of this filter to 1, it will do ac3 passthrough
like hwac3 did.

Substract the delay caused by filter buffering when calculating
currently playing audio position. This matters for af_scaletempo which
buffers significant and varying amounts of data. For other current
filters the effect is normally insignificant.
Instead of the old time-based filter delay field (which was ignored)
this version stores the per-filter delay in units of bytes input read
without corresponding output. This allows the current scaletempo
behavior where other filters before and after it can see the same
nominal samplerate even though the real duration of the data varies;
in this case the other filters can not know the delay they're causing
in terms of real time.

Rewrite decode_audio to better deal with filters that handle input in
large blocks. It now always places output in sh_audio->a_out_buffer
(which was always given as a parameter before) and reallocates the
buffer if needed. After the changes filters can return arbitrarily
large blocks of data without some of it being lost. The new version
also allows simplifying some code.

Most of these functions aren't even used in the same translation unit.

Remove the mul/cancel/gcd functions and some related code. Use ff_gcd
instead of the removed af_gcd in af_resample.c.

Change the audio filters to use a double instead of rationals for the
ratio of output to input size. The rationals could overflow when
calculating the overall ratio of a filter chain and gave no real
advantage compared to doubles.

overflow. Negative values do not seem to be used so just remove the
failing test.
