nb_outputs

@Cast(value="unsigned")

priv

public Pointer priv()

private data for use by the filter

priv

public avfilter.AVFilterContext priv(Pointer priv)

graph

public avfilter.AVFilterGraph graph()

filtergraph this filter belongs to

graph

public avfilter.AVFilterContext graph(avfilter.AVFilterGraph graph)

thread_type

public int 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).

thread_type

public avfilter.AVFilterContext thread_type(int thread_type)

internal

public avfilter.AVFilterInternal internal()

An opaque struct for libavfilter internal use.

internal

public avfilter.AVFilterContext internal(avfilter.AVFilterInternal internal)

variable values for the enable expression

var_values

public avfilter.AVFilterContext var_values(DoublePointer var_values)

is_disabled

public int is_disabled()

the enabled state from the last expression evaluation

is_disabled

public avfilter.AVFilterContext is_disabled(int is_disabled)

hw_device_ctx

public avutil.AVBufferRef 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.

hw_device_ctx

public avfilter.AVFilterContext hw_device_ctx(avutil.AVBufferRef hw_device_ctx)

nb_threads

public int 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.

nb_threads

public avfilter.AVFilterContext nb_threads(int nb_threads)

ready

@Cast(value="unsigned")
public int ready()

Ready status of the filter. A non-0 value means that the filter needs activating; a higher value suggests a more urgent activation.

ready

public avfilter.AVFilterContext ready(int ready)
