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.

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.
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.
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.

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.
CMake build framework 3.0 introduces more strict typing checks, which
require additional code fixes to silence.
* Fixes warnings about implicit casts
* Fixes warnings about weak references used multiple times inside
blocks
When bitrate is updated, a check against 'lookahead' setting is done.
If 'lookahead' is enabled, the bitrate update is disabled.
We indeed used to observe crashes with nvenc when frequent bitrate
resettings were effected while lookahead option was enabled.
But recent tests have shown that the issue is gone.
As a result this commit allows 'lookahead' with bitrate live update.

FFmpeg wipes priv_data if the encoder fails to start, so we need some
way of knowing if the GPU index was non-zero. This is a bit ugly but the
best way to do it for now.
This writes the result of nvEncGetLastErrorString to the last encoder
error instead of just the log file. This makes it user-visible, which
should help users diagnose and solve the problem.
Also strips off leading colons from NVENC error strings as these can
look odd given our format string. An example of such an error:
::NV_ENC_TWO_PASS_FULL_RESOLUTION is only supported multipass encoding
on this architecture.
Receiving buffers flagged as corrupted, or empty, is a casualty of
how things are implemented in various compositors, and it's not
a critical situation to be afraid of. We can expect a few buffers
to be flagged as corrupted here and there, and that's fine.
Demote these warnings to debug messages, as they're still useful
for debugging.
A trivial cosmetic change. This groups the constructor and
destructor together. Two sides of the same coin, yin and yang,
bound by their nature, and linked by their position in code.
This commit introduces an important distinction in the initialization
process that is essential to future camera and audio work: it splits
creating and connecting to the PipeWire socket, from connecting to
specific PipeWire nodes.
Right now, for the only consumer in existence - the ScreenCast portal
code - this distinction is irrelevant, but from an API perspective it
just makes sense to model it this way.
We don't actually need to restore the node id anymore, since this
is handled by the screencast-portal.c code now.
Remove the pipewire_node field, and just create the stream directly
from the passed file descriptor now.
