Fields

av_class: *const AVClass

filters: *mut *mut AVFilterContext

nb_filters: c_uint

scale_sws_opts: *mut c_char

< sws options to use for the auto-inserted scale filters

resample_lavr_opts: *mut c_char

< libavresample options to use for the auto-inserted resample filters

thread_type: c_int

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.

nb_threads: c_int

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.

internal: *mut AVFilterGraphInternal

Opaque object for libavfilter internal use.

opaque: *mut c_void

Opaque user data. May be set by the caller to an arbitrary value, e.g. to be used from callbacks like @ref AVFilterGraph.execute. Libavfilter will not touch this field in any way.

execute: avfilter_execute_func

This callback may be set by the caller immediately after allocating the graph and before adding any filters to it, to provide a custom multithreading implementation.

If set, filters with slice threading capability will call this callback to execute multiple jobs in parallel.

If this field is left unset, libavfilter will use its internal implementation, which may or may not be multithreaded depending on the platform and build options.

aresample_swr_opts: *mut c_char

< swr options to use for the auto-inserted aresample filters, Access ONLY through AVOptions

sink_links: *mut *mut AVFilterLink

Private fields

The following fields are for internal use only. Their type, offset, number and semantic can change without notice.

sink_links_count: c_int

disable_auto_convert: c_uint
