Also modifies libobs & deps/media-playback.
AV_CODEC_CAP_TRUNCATED was removed in avcodec 60 [1].
We ifdef the code depending on it to allow compilation.

As clang and gcc use "default" visibility (as in "not hidden") when
no visibility is specified, all functions are implicitly exported.
When changing default visibility to "hidden", the corresponding symbols
are not exposed anymore and linking fails. This PR updates all
functions signatures that were added in recent commits but not set to
be EXPORTed.
Also makes required OpenGL imports for texture sharing on macOS
mandatory.
This is an option that while very powerful also provides a footgun for
users if they don't have enough memory. It will be helpful for support
volunteers to be able to see if the option has been enabled.
When the `pos` variable is non-zero, audio does not get mixed correctly.
This is due to the fact that the `pos` variable was erroneously being
applied to the input rather than the output.
Stingers -- and especially track matte stingers -- are currently subject
to real time decoding, which can be detrimental in a production
environment where a stinger video may not be able to decode in a timely
fashion.
To remedy this, this change adds an option to fully decode stingers
immediately and cache the decoded video/audio in RAM for playback to
greatly improve stinger performance.
This was needed to get the macOS 13 SDK when Xcode 14.0 was the default.
It no longer is (at the time of writing the default is 14.2), so we can
(and probably should) stop pinning to the older 14.1
DXGI_ADAPTER_DESC's DedicatedVideoMemory and SharedSystemMemory are
unsigned long long int, but we were logging them as unsigned int. For
GPUs with memory values higher than 4294967295, the logged value would
roll over. Use %PRIu64 (%llu on VS2022) instead of %u in the log call.
This makes multiple changes to resolve issues with monitoring. We have
added a number of things over time to resolve various issues due to our
misunderstanding of the pulse api and the explicitly wrong pulse api
documentation.
First is removing the prior stream write tracking. Write tracking
was incorrect as pulse sends you the total number of bytes it wants
written at that time and not a incremental, but also this write tracking
is unhelpful since we can just let begin_write signal when we should
stop writing.
Second removing underflow tracking, this sort of worked to detect high
latency sources like vlc which buffer ~1s of data before writing audio
data. It worked because it would grow the buffer in PA until we could
write enough data into it, but it didn't allow us to leverage that
larger buffer because we never paused the PA stream.
To solve the buffering/high latency issue instead start the PA stream
corked and only uncork it once we have enough data to reach the targeted
latency. We also check how much data we recieve from the source and if
it appears to be high latency providing us with much more data than our
target latency we increase the latency to match the source. Fixing the
VLC source issue and resulting in a smooth start to audio instead of
underruns while we play and increase latency.
Finally add some handling for pulses incorrectly documented API. Notably
that begin_write may request more or less data from you so handle both
cases. And stop attempting to use attr.maxlength which is not updated
after set_buffer_attr calls and was always -1, and tlength is just more
appropriate.
old mantis resulting in some changes, still fixed. https://obsproject.com/mantis/view.php?id=1076fixes#7574
PipeWire allows since 0.3.62 [1] to attach metadata to a buffer
describing a transformation of the buffercontent. Clients should then
undo that transformation to import it correctly.
We can enable this feature using macro guards and runtime server version
checks on supported systems.

Portable mode is meant to be separated from the rest of the system, and
as such it doesn't make sense to load globally installed plugins there.
On Windows, there currently are only two major plugins that install
themselves there. Plugins installing themselves there is good, but it
currently also means that even portable instances load them which can
make testing and debugging in a clean environment annoying.
Previously, all the functions of portable mode wouldn't work if compiled
without it, but the log still show it as enabled if the argument was
set. This could lead to confusion.
Additionally, we don't even show the option in the help string (--help),
so it should just be a no-op.
New video formats introduced for ProRes 4444 encoding have not been
implemented in function calls used for video decoding, which makes the
switch statements non-exhaustive.
This does not functionally change the status quo (decoding ProRes 4444
files could still be broken because libobs does not explicitly handle
the colour format).
Existing code made use of macros which broke parsing in Xcode and
complicated debugging as crucial code was executed within macros and
not actual source code.
Use of mutable CoreFramework data structures (which were never mutated)
is replaced by use of faster non-mutable variants.
When an allocator needs to be used, `kCFAllocatorDefault` is specified
explicitly.
VideoToolbox session properties are also set in bulk instead of
multiple consecutive calls.
Also simplifies detection of Apple Silicon hosts to make code more
readable.
