API changed from: obs_source_info::get_name(void) obs_output_info::get_name(void) obs_encoder_info::get_name(void) obs_service_info::get_name(void) API changed to: obs_source_info::get_name(void *type_data) obs_output_info::get_name(void *type_data) obs_encoder_info::get_name(void *type_data) obs_service_info::get_name(void *type_data) This allows the type data to be used when getting the name of the object (useful for plugin wrappers primarily). NOTE: Though a parameter was added, this is backward-compatible with older plugins due to calling convention. The new parameter will simply be ignored by older plugins, and the stack (if used) will be cleaned up by the caller.
