Function ffmpeg_sys_the_third::avfilter_register

pub unsafe extern "C" fn avfilter_register(
    filter: *mut AVFilter
) -> c_int

Register a filter. This is only needed if you plan to use avfilter_get_by_name later to lookup the AVFilter structure by name. A filter can still by instantiated with avfilter_graph_alloc_filter even if it is not registered.

@param filter the filter to register @return 0 if the registration was successful, a negative value otherwise
