libavcodec/idctdsp.c(175) : warning C4028: formal parameter 2 different from declaration

It is more efficient and so preferred over allocating the buffers
manually.

The four examples (audio/video encoding/decoding) are completely
independent so it makes little sense to have them all in one file.

This matrix needs to be applied after all others have (currently only
display matrix from trak), but cannot be handled in movie box, since
streams are not allocated yet. So store it in main context, and apply
it when appropriate, that is after parsing the tkhd one.

Fate tests are updated accordingly.

This is needed for improved fate testing and it is modeled after
-show_format_entry. The main behavioral difference is that when a print
function is called with an empty key, rather than discarding it, the
closes key in the hierarchy is used instead.

The use of TLSv1_*_method() disallows newer protocol versions; instead
use SSLv23_*_method() and then explicitly disable the deprecated
protocol versions which should not be supported.

Avoid an underlink issue on recent distributions.

This reverts commit 7d8d726be7.

Fixes several warnings from -Wformat.

libavcodec/hapenc.c:121:20: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 4 has type ‘size_t {aka unsigned int}’ [-Wformat=]
libavcodec/hapenc.c:121:20: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘size_t {aka unsigned int}’ [-Wformat=]

This also kills some warnings with certain compiler options.

The code has little usefulness and uses the __PRETTY_FUNCTION__ GNU extension.

The output is rather silly and the code uses non-standard __FUNCTION__.

libavcodec/h264_loopfilter.c:531:111: warning: variable 'edge' is uninitialized when used here [-Wuninitialized]

libavcodec/mpegaudiodec_template.c:885:97: warning: variable 'x' is uninitialized when used here [-Wuninitialized]

Since avversion.h is a generated header it must be created before
dependencies can be determined as a side effect of compilation.
Otherwise Make stops and restarts the build process to generate
avversion.h and produces related error messages.

When the macro is expanded with a semicolon following it and the
macro itself contains a semicolon, we ended up in double semicolons,
which is treated as a statement that disallows further declarations.

This avoids errors about mixed declarations and statements on gcc,
after ee05079766.

Useful to test protocols that require options to be used.

The buffer map/unmap code was in an early version of this before it
was committed, but the unmap was never removed.  While wrong, this
was harmless (and therefore unnoticed) because the buffers can't be
mapped at this point - all drivers just did nothing with the call.

When decoding interlaced pictures, the structure is reused to render
to the same surface twice.  The parameter buffers were not being
cleared, which caused the i965 driver to error out.

Use new H264Ref.reference field to track field picture flags. The
H264Picture.reference flag in DPB is now irrelevant here.

This is a regression from git commit a12d3188, and that affected
multiple interlaced video streams.

Instead use our own struct, which we already use when using
gcrypt and gnutls.

In OpenSSL 1.1, the DH struct has been made opaque.

sigaction is not defined in standards as a struct starting with another
struct. Some *BSD variants do however, resulting in a warning from the
zero initialization, which this change eliminates.

For 'nclx', the latest edition of the standard switched from JPEG XR
to 23001-8, which matches the current order of our entries. Bounds
are preserved as a sanity check.

For 'nclc', qtff edition 2016-09-13 introduced a few new entries.
