When the mode is set to auto, the API sometimes send frames with 0x0
size. Without filtering such frames, which causes libobs to output error
messages.
This change fixes an issue with the CMIO DAL plugin where the CMIO
subsystem would log multiple errors when starting the virtual camera,
due to certain properties that could not be set (frame rate and format).
For now, we just ignore the assignment, but mark the property as
settable to suppress the error messages that are reported by the CMIO
subsystem.
This change fixes an issue in the Mach server exposed by the macOS
virtual camera for OBS, where it would not invalidate ports that were
disconnected by the remote application, causing sporadic crashes.
These crashes can be reproduced in the previous builds by opening the
virtual camera in a remote application and closing the application
(without stopping the virtual camera).
This change updates the implementation of the mac-virtualcam plugin to
not use any global state and instead rely on the state object that is
passed by the OBS module system.
This approach is similar to the virtual camera implementations for Linux
and Windows.
This change removes the unused CMSampleBuffer utility functions that
were still left from the previous implementation. Since we construct the
CMSampleBuffer directly from an IOSurface, we do not need any custom
construction logic anymore, since that is now performed by the OBS
plugin.
This change updates the mac-virtualcam implementation to conditionally
enable conversion of the output video format. Previously, the output
video was always converted into UYVY. However, this conversion exhibits
high CPU usage, as reported in:
https://github.com/johnboiles/obs-mac-virtualcam/issues/102
Therefore, we disable conversion when the selected output format (e.g.,
NV12) is natively supported by CoreVideo's pixel buffers.
This change updates the plugin to support video formats that contain
multiple planes (such as NV12). Such functionality is necessary to
prevent transcoding the raw video data, which is often delivered in a
planar format.
This change updates the mac-virtualcam implementation to pool the
CVPixelBuffers used to share the output frames. This allows the plugin
to recycle the pixel buffers used by the plugin.
This change updates the virtual camera implementation on macOS to
utilize IOSurface to share the output feed with the virtual cameras.
By using IOSurface, we remove the need for copying the frames across
multiple buffers, since they can be shared across Mach connections using
zero-copy.
This change fixes an issue where the DAL plugin would not load due to
not supporting the architecture arm64e. We update the build
configuration to build a universal binary that includes arm64e as well.
See https://github.com/obsproject/obs-studio/issues/6285 for more
information regarding this issue.
Sometimes when reconnecting the internal RTMP data is not cleared
(particularly the TLS data). This can cause TLS data to carry over from
one connection to another, causing issues with the secondary connection.
Due to a bug in shader parsing, it thinks that because the token
"multiplier" is used here, that the "multiplier" uniform is being used.
This is a workaround for the issue because fixing the parser is probably
going to be much more annoying than just working around the issue for
now.
In bb6787968, we changed the default behaviour to be strict modifiers
and we consider this to be the correct way. There is no need to change
this from code either, since if someone really needs non-strict
modifiers, they can work around it by setting multiple hotkeys.
Having this option in code just means a bigger maintenance cost, so
we'll deprecate the function and remove it in the future.
This adds a circular buffer to ffmpeg-mux when writing to a file.
Output from ffmpeg is buffered so that slow disk I/O does not block
ffmpeg writes, as this causes the pipe to become full and OBS stops
sending frames with a misleading "Encoding overloaded!" warning. The
buffer may grow to 256 MB depending on the rate of data coming in and
out, if the buffer is full OBS will start waiting in ffmpeg writes.
A separate I/O thread is responsible for processing the contents of
the buffer and writing them to the output file. It tries to process 1 MB
at a time to minimize small I/O.
Complicating things considerably, some formats in ffmpeg require seeking
on the output, so we can't just treat everything as a stream of bytes.
To handle this, we record offsets of each write and try to buffer as
many contiguous writes as possible. This unfortunately makes the code
quite complicated, but hopefully well commented.
CMake config files are required for building OBS plugins with the
Flatpak as a runtime.
Add a post-install command that installs the `obs_libraries`
component, which provides the config files.
This limits the length of the name label in the advanced audio
dialog to 80 characters, so the dialog doesn't get too wide. If the
name is truncated, "..." are added at the end of the label, and the
label's tooltip is set to the full name of the source.
If obs_core_hotkeys.strict_modifiers is true (new default),
hotkey is triggered only if current key modifiers exactly match
the hotkey definition. If false, legacy behavior is selected.
This hooks the platform specific events in order to close the obs
display more accurately. Earlier attempts on hooking visiblity, but Qt
does not ensure that visibility is changed before the surface is
destroyed. So we ended up racing with the EGL driver and on some
drivers if you lose the race they hang.
Also only force display creation if the display is actually visible.
When a source type is not video/drawable (or is missing) this would
force the display to be created for the blank window and also hang.
Finally force closure of the preview displays during scene cleanup to
avoid similar ordering issues in Qt. Qt has even less order guarentees
during close and we are sure that displays are no longer needed at this
point in the UI.
