Detailed Description

An instance of a filter

Member Data Documentation

◆ av_class

const AVClass* AVFilterContext::av_class

needed for av_log() and filters common options

◆ command_queue

struct AVFilterCommand* AVFilterContext::command_queue

◆ enable

void* AVFilterContext::enable

parsed expression (AVExpr*)

◆ enable_str

char* AVFilterContext::enable_str

enable expression string

◆ filter

const AVFilter* AVFilterContext::filter

the AVFilter of which this is an instance

◆ graph

struct AVFilterGraph* AVFilterContext::graph

filtergraph this filter belongs to

◆ hw_device_ctx

AVBufferRef* AVFilterContext::hw_device_ctx

For filters which will create hardware frames, sets the device the filter should create them in. All other filters will ignore this field: in particular, a filter which consumes or processes hardware frames will instead use the hw_frames_ctx field in AVFilterLink to carry the hardware context information.

◆ input_pads

AVFilterPad* AVFilterContext::input_pads

array of input pads

◆ inputs

AVFilterLink** AVFilterContext::inputs

array of pointers to input links

◆ internal

AVFilterInternal* AVFilterContext::internal

An opaque struct for libavfilter internal use.

◆ is_disabled

int AVFilterContext::is_disabled

the enabled state from the last expression evaluation

◆ name

char* AVFilterContext::name

name of this filter instance

◆ nb_inputs

unsigned AVFilterContext::nb_inputs

number of input pads

◆ nb_outputs

unsigned AVFilterContext::nb_outputs

number of output pads

◆ nb_threads

int AVFilterContext::nb_threads

Max number of threads allowed in this filter instance. If <= 0, its value is ignored. Overrides global number of threads set per filter graph.

◆ output_pads

AVFilterPad* AVFilterContext::output_pads

array of output pads

◆ outputs

AVFilterLink** AVFilterContext::outputs

array of pointers to output links

◆ priv

void* AVFilterContext::priv

private data for use by the filter

◆ thread_type

int AVFilterContext::thread_type

Type of multithreading being allowed/used. A combination of AVFILTER_THREAD_* flags.

May be set by the caller before initializing the filter to forbid some or all kinds of multithreading for this filter. The default is allowing everything.

When the filter is initialized, this field is combined using bit AND with AVFilterGraph.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.

After the filter is initialized, libavfilter sets this field to the threading type that is actually used (0 for no multithreading).

◆ var_values

double* AVFilterContext::var_values

variable values for the enable expression
