faba1501d5 avfilter/vsrc_gfxcapture: switch to std::thread 
Combining C++ with our w32pthreads does not work out.
The C++ standard lib headers might include pthread.h, which will then
define clashing types with our w32pthread header.

To solve this, switch to using C++ native std::thread.

0773343ed7 avcodec/rkmppdec: fix input queue overflow 
The strategy to count free slots isn't reliable. The value of
INPUT_MAX_PACKETS is a hardcoded value, and MPP_DEC_GET_STREAM_COUNT
doesn't always work as expected. When freeslots is nonzero, the mpp
decoder still returns MPP_ERR_BUFFER_FULL. Before this patch, all
packets are dropped once went into MPP_ERR_BUFFER_FULL state.

Don't drop packet and return error in MPP_ERR_BUFFER_FULL state.
Receive frame to allow the decoder's state machine to resume.

5146b2fb8b configure: don't use MinGW ANSI stdio when using UCRT 
MinGWs ANSI stdio is quite slow, and when using UCRT, its extra features
are not needed.
The only troublesome part with ucrt printf is that is disagrees about
the size of "long double", but FFmpeg does not use that anywhere, let
alone prints it.

0ce413af9c configure: properly split C/CXX and CPP flags 
Right now, CFLAGS like -std=c17 leak onto the C++ compilers commandline,
leading to tons of warnings and even some errors.

Undefining __STRICT_ANSI__ causes strong warnings from the stdlib
headers. So only set it for C.

4c80cda08a forgejo: make aarch64 asm linter part of pre-commit

edd1b93e53 forgejo: Check the aarch64 assembly indentation as part of the lint job 
Alternatively, this could be a separate job, potentially keyed
to only run on PRs that touch files matching */aarch64/*. But
as this runs very quickly, it's probably less clutter to just
bundle it here.

a3ce337926 tools: Add scripts for indenting and checking aarch64 assembly 
The same also applies for arm assembly, but there are more known
deviations within that.

Add a script which checks all files, except for a few known files
that deviate, for various reasons.

9ae42d42e6 avcodec/dvdsubdec: Don't return value != 0 on init success 
Currently, any nonnegative return value from an init function
is just treated as success and otherwise ignored; while it is
not explicitly forbidden to return something else than 0 (there
is no documentation whatsoever), the assumption is that
they return zero on success. So change dvdsubdec.c accordingly.

Also change dvdsub_parse_extradata() to return zero on success.

5f39965dd6 avfilter/buffersink: remove unneeded parameter

05b6b30ee1 fftools/ffplay: set the alphamodes buffersink array option instead of the binary one 
And add the missing goto fail. This should ensure the alpha mode is set and remove
bogus warnings printed by ffplay.
