Since a private class is set for this muxer, the callers will
assume that the private data starts with an AVClass pointer.
If no such member exists, the first few bytes of the struct
will be overwritten, and the class pointer may be broken at
any later time.

When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Fixes occasional one-off effects when enabling slice-MT.

The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

This is consistent with how all other table generation programs are named.
Moreover this ensures that the cos table generation program is correctly
deleted when cleaning the tree.

tableprint.c serves little purpose on its own and removing it allows building
the table generator programs with the normal HOSTPROGS Makefile rules.

This collapses the make rules for the trig tables into a pattern
rule.  Based on a patch by Diego, modified to avoid using fragile
make constructs and allow future addition of fixed-point sin tables.

Older nasm versions have trouble assembling certain AVX instructions, but the
current AVX check did not detect this. Update the check to use an instruction
that triggers the nasm problem.

These structs are only used in mpegaudiodec.c, so move them there
and remove no longer needed #include lines from mpegaudio.h.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

inttypes.h is not necessary, just stdint.h is enough.
Unconditionally #include avfilter.h in cmdutils.h.  It is an installed
header with no non-standard external dependencies, so it is safe.

The header contains just a single define that is only used in g729dec.c.

Based on patches by clsid2 in ffdshow-tryout.

This will allow audio decoders to support output of different sample formats
as a runtime option.

The ref targets are included in the FATE_[AV]CODEC lists created
by configure so they do not need to be listed separately in the
makefile.  Filter them out when setting dependencies to avoid make
warnings about circular deps.

This function is essentially an alias for run_ffmpeg and is only
used in one place.  This patch removes the function and replaces
the call with the equivalent (simpler) run_ffmpeg call.

These tests create reference files used for psnr calculation in
the other codec tests.  Treating them as (mostly) regular tests
simplifies the makefile and makes them visible in the fate reports.
The latter makes errors in these runs easier to identify.
