Due to the recent change in which scene items now only update their
transforms during the next frame's tick, snapping sources would
sometimes jitter and have incorrect snapping. This fixes that issue by
reverting to the behavior of updating the transform immediately rather
than deferring the update to the next frame tick, but only on non-group
items.
This should not be done on items that are sub-items of groups because we
rely on the obs_scene_item::update_transform variable to update the
parent group's transform in addition.
Instead of updating the scene item texture any time
update_item_transform() is called, only update it when
obs_scene_item::update_transform is called. Prevents having to lock the
graphics mutex needlessly.
As of commit 2eb5a22, CoreAudio devices that use one device handle for
both input and output can no longer be used for audio monitoring. This
commit fixes that.
Tested with the built-in output, a Magewell XI100DUSB-HDMI which is
input only, and a MOTU UltraLite audio interface, which shows as
output/input capable.
If the scene item crop/filtering is updated, instead of
creating/destroying the item texture on the spot, update it in the
graphics thread to prevent potential race conditions (especially when
the crop function for example could be called from within
obs_scene_enum_items in some situations, which would lock the graphics
and scene mutexes in the wrong order).
(This commit also modifies UI)
Changes groups to their own independent type, "group". This allows them
to be used like other regular types, and allows the ability to reference
groups in multiple scenes. Before, a group would always be linked to
the scene it was in. This made it cumbersome for users to modify groups
if they had a similar group in multiple scenes (they would have to
modify each group in each scene). Making groups like other source types
makes more sense to solve this issue so they can be referenced in
multiple scenes at once. This also removes a significant amount of
group-specific handling code required for implementing groups in the
front-end.
One limitation however: due to the way sub-items of groups are
seamlessly modifiable and sortable as part of the whole scene, the user
cannot have multiple references to the same group within one scene.
(This commit also modifies UI)
Removes obs_scene::group_sceneitem and replaces it with
obs_scene::is_group. Changes a number of other functions related to
groups so that a group is not inherently tied to a specific scene, and
helps allow a single group to be referenced in multiple scenes if
desired.
This function returns a char *, so it should not be const (the value is
set from a function which also returns a char *, so there is no real
reason for this to be const).
When using a macOS running on a case-sensitive filesystem, the project
build fails due to AudioToolBox/AudioQueue.h not being found.
The correct path is AudioToolbox/AudioQueue.h. Since macOS comes with a
case-insensitive filesystem by default, this is a rare ocurrence
among developers who change it to be case-sensitive.
This little change skips returning true immediately when a call to
CoreAudio fails. Instead, it uses similar behavior as further 3 calls
below this change, just checking for unfreed pointers before also
returning true.
Allows the ability to group scene items. Groups internally are
sub-scenes, which allows the ability to add unique filters and
transforms to each group.
Fixes a bug where items that had cropping would recalculate transform
every frame. obs_scene_item::last_width and obs_scene_item::last_height
would be set to the cropped sizes rather than the source's actual size.
Adds a simple signal reference counting function
(signal_handler_connect_ref) that makes it so that signals keep the
handler around until the all the signal itself is disconnected. This
prevents potential crashes where a signal might try to disconnect after
a handler has already been destroyed (typically in C++ with
OBSSignalHandler helper objects, where destruction isn't guaranteed to
be predictable).
This also modifies OBSSignalHandler to use the reference-counting
connections.
