Currently creating new sources can cause a deadlock:
OBSBasicSourceSelect locks the scene mutex when adding a new source
(required to add invisible sources), and later OBSBasic tries to
lock the graphics mutex (via CreatePropertiesWindow); meanwhile the
graphics thread is holding the graphics mutex and tries to lock each
scene as it renders them, resulting in a (non-obvious from the code)
lock ordering conflict.
Moving the CreatePropertiesWindow call out of the locked scene mutex
restores the previous lock ordering; in addition, the requirement
for keeping sourceSceneRefs for opening that initial properties
window is removed
Typedef pointers are unsafe. If you do:
typedef struct bla *bla_t;
then you cannot use it as a constant, such as: const bla_t, because
that constant will be to the pointer itself rather than to the
underlying data. I admit this was a fundamental mistake that must
be corrected.
All typedefs that were pointer types will now have their pointers
removed from the type itself, and the pointers will be used when they
are actually used as variables/parameters/returns instead.
This does not break ABI though, which is pretty nice.
The naming here is a poor choice, a source type determines if a source
is either a regular input, a filter, or a transition. The ID is the
actual unique identifier of a source.
Add a 'source selection' dialog to replace the 'enter a name' dialog.
This new dialog allows you to make new instances of pre-existing sources
so that you can add a pre-existing source to a different scene, or in to
the same scene more than once.
Also started implementing locale.
Comtemplating switching to JSON-based locale later, so we can add things
like descriptions/disambiguation, and so we can use jansson's built-in
hash table when doing the string lookup.
