The header packets are only used within the rtmp-output and do not need
or use the ref counter as the data is manually free'd directly.
The presence of this ref counter causes a crash on *nix platforms due to
our memory alignment hack attempting to free memory but reading the
wrong offset due to the ref counter being there rather than the
alignment offset.
The `done` event does not emit a `closeEvent`, but saving is only
implemented in that event handler. Changing this to `close` correctly
triggers the default QWidget event and thus settings are saved.
The format is only checked for 10-bit capable formats, which in this
case applies to HEVC only. When HEVC is disabled, then `format` is
not checked and becomes an unused variable otherwise.
Fixes an issue where update/destroy of a media source during reconnect
would block the parent thread until the next reconnect attempt. This
would result in significant quantities of dropped frames, delayed OBS
shutdown, or frozen UI during this period.
Xcode 14.3 and the macOS 13.3 platform SDK introduced a few breaking
changes:
* Updated AppleClang emits warnings about unqualified std cast calls
when using C++ - as `move` is too broad a word, developers are to use
`std::move` to make this explicit. Alas this is exactly what `json11`
uses and because that library is archived, there is no possibility
of an upstream update.
* Apple guarded calls to old screen capture APIs as "available but
deprecated", but seems to have chosen the wrong lower version
boundary: The calls are flagged as being available for macOS 13 and
macOS 14 only.
To fix this, the existing macOS platform SDK header is replaced by a
local copy that uses macOS 11 as the lower boundary (the oldest macOS
version supported by obs-studio anyway)
In avcodec.h, the docs for AVCodecContext->framerate say:
encoding: May be used to signal the framerate of CFR content to an
encoder.
OBS is designed to always output Constant Frame Rate (CFR) content.
Instead of letting this be implied, let's explicitly set the framerate
per the docs.
Notable changes:
* deps.ffmpeg: Update FFmpeg to a6dc92968a
* deps.qt: Backport macOS disabled combobox items fix
The FFmpeg update is to fix an issue with DTS when using b-frames with
FFmpeg NVENC. In particular, we wanted this commmit:
* a6dc92968a
When using FFmpeg-based NVENC, with b-frames, and a non-1 framerate
numerator (eg. `1001/60000` aka 59.94fps), the DTS values outputted
by FFmpeg result in invalid DTS values.
Detect when using an unpatched FFmpeg build and correct the values
accordingly.
Every time a media player instance would be initialized, it would
create a new `Set FFmpeg options:` log message. With lots of looping
media sources, this gets incredibly spammy. It's already being logged
by the media source itself, so this line is pretty much unnecessary.
