Transition from using popen() to using fork()/dup2()/execl() to provide
a way to read stderr from ffmpeg.

MSVC noticed inline is not allowed, and new/delete replacments also
don't belong in a header file. We're also just leaning on
__STDCPP_DEFAULT_NEW_ALIGNMENT__ being 16 for MSVC x64 now.
To prevent sources from having to take too much extra consideration into
threading, defer the media control functions that directly affect
functionality to the video thread. Getters will still have to take
threading into account, but this should make things much more trivial
for media controls thread-wise.
(Lain note: Context: I noticed that things such as the slide show
require mutexes due to their media controls, and I felt that it was
largely unnecessary and that libobs should mitigate the threading issue
itself and keep it all in the video thread like it should be. Again, the
getters are still going to require *some* consideration into threading
but in terms of threading, for the type of stuff we're doing, querying
state is far more trivial to take into consideration.)
The OBS_SOURCE_CONTROLLABLE_MEDIA flag is required for controllable
media callbacks to be usable. These checks are being added so we can
defer most controllable media callbacks to the video thread.
(Lain note: This is mostly so more (yes more) can be added to this
god-forsaken structure without it getting too messy. In terms of actual
code, I need to be better about writing actual code comments. ...Meaning
that I actually need to start writing code comments.)
find_qt was necessary during the transitional period between Qt5 and
Qt6. With Qt6 being the only supported Qt version (for open source) for
the time being, code complexity can be reduced for easier maintenance.
While the NSURLVolumeAvailableCapacityForOpportunisticUsageKey resource
correctly reports available disk space for local volumes (regardless
of actual file system used), it does not report actual values for
attached network drives.
The NSURLVolumeAvailableCapacityKey resource will still report
available disk space as expected, so use this value for non-local
volumes instead.
If an item's show/hide transition was active the underlying source
would not previously not be enumerated, resulting in reference leaks by
the UI or other components waiting for the source to be deactivated to
release it.
Fixes for using FFmpeg 6.1 due to deprecations. Uses `#if` macros to
allow builds for using older versions of FFmpeg.
This commit prevents obs from using the "fenced" code if using FFmpeg
6.1, since in FFmpeg commit [1] the "side_data" is added to
`AVCodecParameters`, and therefore the existing/following
`avcodec_parameters_copy(...)` will account for the metadata.

When using a PTS divisor, OBS would still increment the PTS by only the
original `fps_den` value, not considering that PTS values should be
multiplied by the divisor.
For example, `60/1` increases like `0,1,2,3`. `60000/1001` increases
like `0,1001,2002,3003`.
Without this fix, `60/1` main OBS framerate with a divisor of `2`
produces `0,1,2,3`, while the correct pattern would be `0,2,4,6`
While filters are saved using obs_save_source other mutex are used.
To prevent a deadlock, don't keep the filter mutex iterating the filters.
This fixes#9893
Removes the internal helper `remove_without_release()` and branches
`obs_sceneitem_remove()` into public and internal versions.
The `obs_sceneitem_set_transition()` calls were missing from the
`remove_without_release()` function, so this resolves that issue
implicitly. Code cleanup mentioned above is done to hopefully avoid
these mistakes again.
