While we only add the flag if the linker seems to support it,
it turns out that ld.bfd had a bug where the flag is accidentally
accepted, and the flag produces an output file named
"_warn_duplicate_libraries".
The ld.bfd bug was fixed in binutils 2.36, in
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=3991c7acb29aa8d7d52150695eb3efa03a08dd50.

"int-list" options are a hack that provides rudimentary support for
array-type options by treating them as byte arrays (i.e.
AV_OPT_TYPE_BINARY). Since we now have proper array-type options, they
should replace "int-list" everywhere (which happens to be just
buffersink).
I plan to look after and test them for the forseeable future.
I am not a committer but do care for these muxers/demuxers.

This extends the syntax for specifying input streams in -map and complex
filtergraph labels, to allow selecting a view by view ID, index, or
position. The corresponding decoder is then set up to decode the
appropriate view and send frames for that view to the correct
filtergraph input(s).
Having macros initialize local variables seems strange to me, and there
are no more current users of these macros. (The one that was commented
out was incorrect anyway, since the macro has changed in the meantime)
Implement load/save loop filter and segment parameters defined in
section 7.20 and 7.21 in spec for show_existing_frame frames.
Fixes ticket #11151.

add more stringent restrictions. when pause, do not
enqueuebuffer to the driver. This cen avoid the problem
of noise caused by pause twice.

The color range should be set to match the input when creating
the VideoToolbox context. Otherwise, the new context will default
to limited range, creates inconsistencies with full range inputs.

This approach has the major advantage that only parsing can fail (due to
a malformed specifier or memory allocation failure). Since parsing is
done generically, while matching is per-option, this will allow to
remove substantial amounts of error checking code in following commits.
The new code also explicitly allows stream specifiers to be followed by
additional characters, which should allow cleaner handling of optional
maps, i.e. -map <stream_specifier>?, which is currently implemented in a
hacky way that breaks when the stream specifier itself contains the '?'
character (this can happen when matching metadata). It will also allow
further extending the syntax, which will be useful in following commits.
This introduces some minor behaviour changes:
* Matching metadata tags now requires the ':' character in keys or
values to be escaped. Previously it could not be present in keys, and
would be used verbatim in values. The change is required in order to
know where the value terminates.
* Multiple stream types in a single specifier are now rejected - such a
specifier makes no sense.
* Non-existent stream group ID or index is now ignored with a warning
rather than causing a failure. This is consistent with program
handling and is required to make matching fail-free.
This has multiple advantages:
* The macro has multiple parameters that often have similar or identical
values, yet very different meanings (one is the name of the
OptionsContext member where the parsed options are stored, the other
the name of the variable into which the result is written); this
change makes each of these explicit.
* The macro returns on failure, which may cause leaks - this was the
reason for adding MATCH_PER_STREAM_OPT_CLEAN(), also ost_add()
currently leaks encoder_opts. The new function returns failure to its
caller, which decides how to deal with it. While that adds a lot of
error checks/forwards for now, those will be reduced in following
commits.
* new code is type- and const- correct
Invocations of MATCH_PER_STREAM_OPT() with other types will be converted
in following commits.
Callers of ff_framesync_get_frame() generally do not expect the result
to be writable, those that do (e.g. ff_framesync_dualinput_get_writable())
ensure writability themselves.
Significantly reduces memory consumption in complex graphs with
framesync-based filters (e.g. scale, ssim).

The search of the current DirectShow device list has been customized so
that audio devices are always found even if no video device is connected.
