char* AVFilterGraph::resample_lavr_opts

Referenced by configure_filtergraph().

int AVFilterGraph::thread_type

Type of multithreading allowed for filters in this graph.

A combination of AVFILTER_THREAD_* flags.

May be set by the caller at any point, the setting will apply to all filters initialized after that. The default is allowing everything.

When a filter in this graph is initialized, this field is combined using bit AND with AVFilterContext.thread_type to get the final mask used for determining allowed threading types. I.e. a threading type needs to be set in both to be allowed.

int AVFilterGraph::nb_threads

Maximum number of threads used by filters in this graph.

May be set by the caller before adding any filters to the filtergraph. Zero (the default) means that the number of threads is determined automatically.
