Some compositors send buffer crop information even when the crop
matches the buffer size. It doesn't really matter in practice,
but it's good hygiene to check for the effective crop instead of
simply checking if crop exists.
Move code into auxiliary functions, to improve the legibility of the
draw function. It also gets rid of these pesky switch fallthroughs.
No functional changes.
In the non-DMA path, we are logging an error message saying that
the DMA format is wrong. That's not the DMA format, it's the raw
buffer format.
Fix the message.
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.
