Make af_format clamp float sample values to the range [-1, 1] before
conversion to integer types. Before any out-of-range values wrapped
around and caused nasty artifacts. This filter is used for all
automatic format conversions; thus any decoder that outputs floats
with possible out-of-range values would have been affected by the bad
conversion if its output needed to be converted to integers for AO.
Reordering to libavcodec channel order was broken with libavcodec
versions using float input to the ac3 encoder because the reordering
code still assumed int16 sample size. Fix.
af_lavcac3enc: use old SampleFormat names without AV_ prefix, the
latter were only added in 2010-11
vd_ffmpeg: add ifdef around CODEC_ID_LAGARITH use
demux_real: use ffmpeg_files/intreadwrite.h
stream/http.c, stream/realrtsp/real.c: define AV_BASE64_SIZE macro for
old libavutil versions lacking it
The libavcodec AC-3 encoder was changed to use floats, and take
floating point samples as input (the fixed-point version is still
available under the new name "ac3_fixed"). This broke af_lavcac3enc
because it blindly assumed without checking that the "ac3" encoder
would take signed 16-bit integer samples. Improve af_lavcac3enc so
that it checks the sample formats supported by the encoder and can
handle either int16_t or float.
Perhaps an option to keep using integer input but instead switch the
encoder name to "ac3_fixed" for new libavcodec versions would have
some value. Then again, maybe not. Using the preferred data format of
the default "ac3" encoder should normally be best, so probably better
not add such an option unless real need appears.
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).

Refactor more instances of avcodec_initialized handling into init_avcodec().
This is a leftover from the previous commit.

Avoid calling av_resample_init again when the values are the same as before.
The init function can be called multiple times when e.g. additional format
filters are inserted, so this speeds things up.

The code handling input format negotiation incorrectly used the bps
value of the suggested input format instead of the format it was going
to actually use. As a result the player could abort with the above
assertion failure. Fix.
The only FFmpeg internal symbols required were some constants. Define
them in the file itself instead. Also add some checks and fixes to
make the code more robust and fix a potential memory corruption
problem.
These files now contain different functions related to path handling.

Note that r30455 is wrong, that commit does not in fact change the
default behavior as claimed in the commit message. It only breaks
"-af-adv force=0", which was already pretty much useless though.
Tweak some code parts that used to rely on string literals from
translation macros being concatenated with other adjacent string
literals. Break up the resulting string into independently translated
parts, so that the existing translations for those parts can still be
used.
For some reason commit e306174952, which
replaced translation macro names with the corresponding English
strings, also collapsed multiple consecutive space characters into
one. Change most of these back. In a couple of cases the amount of
whitespace is important for alignment, and for the rest it at least
keeps the strings closer to the existing translations.

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

Only 1/3 of the samples in the buffer passed to reorder_channel_nch()
were being reordered. For 8-, 16-, and 32-bit audio, the buffers could
be treated as int8_t, int16_t, and int32_t respectively. 24-bit audio
was being processed as int8_t, requiring iteration over n_samples*3, not
n_samples.

The scaletempo filter has a special-case check to return the samples
unchanged if the current scaling factor is 1. In this case code
setting af->delay wasn't run. If the scale had had a different value
and then been changed to 1 as a result of a playback speed change then
the delay field could have a nonzero value left, resulting in A/V sync
errors. Fix by setting the delay field to 0 in the scale == 1 special
case code.
Where 8 channel support is non-trivial (e.g. ao_dsound), at least ensure we
fail gracefully.

As part of merging subtitle-in-terminal changes make
update_subtitles() only clear existing subtitles if called with the
reset argument, and not try to set new ones. Later calls should set
the needed new subtitles, and this change avoids some problems with
trying to set subtitles when mp_property_sub() in command.c gets
called from initialization code before full initialization.
