When the program first starts up, or rather when a scene collection is
loaded, the frontend API OBS_FRONTEND_EVENT_SCENE_CHANGED event would
not get triggered.
The "obs" global variable can still be accessed by functions during
shutdown. To prevent access to the variable during shutdown, move the
pointer to a temporary function variable, and set the "obs" global
variable to NULL before shutting down.
Individual property objects would store pointers to strings rather than
copies of the strings and assume that memory would continue to exist, so
instead just duplicate the strings.
Because it would be troublesome to add the ability to remove source
types (in case for example a script fails to reload), instead make it so
source types can be temporarily disabled while the program is running.
Convenience function that allows removing the current signal handler
callback within the callback without having to use
signal_handler_disconnect with all of its required parameters.
When splitting a string in to a string list via stringlist_split, it
would previously allocate memory for each sub-string and again for the
list itself. This optimizes that function to use a single contiguous
chunk of memory for the sake of access optimization and memory
allocation efficiency.
(Note: This commit also modifies UI and test)
This makes it so that main preview panes are rendered with the main
output texture rather than re-rendering the main view. The view will
render all objects again, whereas the output texture will be a single
texture render of the same exact thing.
Also fixes some abnormal artifacting when scaling the main preview pane.
If the target process re-creates its D3D context, the game capture tick
can trigger before the capture is setup, in which case OBS gets a
CAPTURE_RETRY message. However with the memory capture method, it
continues to try and copy from the shared memory pointer which is no
longer valid, resulting in a crash. The fix uses the old texture until
the next tick at which point the new capture should be ready for use.
Windows SDK 10.0.16299.0 defines these structures as part of winternl.h
but using different types and names. Unfortunately there's no macro to
detect the SDK version, so to avoid conflicting with newer / older SDKs
the OBS structs have been renamed.
When this was being fixed up, the incorrect function name was used --
however it still compiled because the author was using the newer FFmpeg
version at the time.
The AVCodecParameters weren't introduced until avcodec version 57.48.101
(FFmpeg version 3.1), so this will make sure to still use the older
avcodec_copy_context if the detected FFmpeg version is earlier.
Some CMake checks were recently switched from UNIX to LINUX to get them
to not apply to macOS/OSX. Since LINUX doesn't seem to be defined,
switch these checks to UNIX AND NOT APPLE.
This reverts commit de32d89fc6ac1cc85346732f722fe74ac1cb1eca.
Fixes an issue where Linux CI builds fail because FFmpeg fails to
compile. Using FFmpeg git master in CI builds was obviously not the
smartest idea because changes in FFmpeg can break things unexpectedly.
Sorry about that.
The reason for the original commit was that OBS failed to compile
with FFmpeg 2.4. That has been fixed since.
