Remove majority of warnings There were a lot of warnings, managed to remove most of them. Also, put warning flags before C_FLAGS and CXX_FLAGS, rather than after, as -Wall -Wextra was overwriting flags that came before it. 2014-02-14 14:13:36 -08:00			`#define UNUSED_PARAMETER(param) (void)param`

libobs: Deprecate obs object addref functions Deprecates: obs_source_addref() obs_output_addref() obs_encoder_addref() obs_service_addref() obs_scene_addref() These functions should be considered unsafe and not used. Instead, use: obs_source_get_ref() obs_output_get_ref() obs_encoder_get_ref() obs_service_get_ref() obs_scene_get_ref() These functions return a pointer to the incremented object only if the object is still valid, otherwise they will return null, indicating that the object is no longer valid or is unsafe to use. The reason why this is being done is because certain third party plugins seem to be using addref, and are somehow managing to call addref on sources that have already been fully released. For the sake of safety, almost all usage of these functions within OBS have also been replaced as well. 2022-01-24 12:07:02 -08:00			`#define OBS_EXTERNAL_DEPRECATED`
