| struct AVFilterGraph* AVFilterContext::graph |
filtergraph this filter belongs to

| 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).

| 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.

| 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.
Definition at line 455 of file avfilter.h.
| unsigned AVFilterContext::ready |
Ready status of the filter.
A non-0 value means that the filter needs activating; a higher value suggests a more urgent activation.

| int AVFilterContext::extra_hw_frames |
Sets the number of extra hardware frames which the filter will allocate on its output links for use in following filters or by the caller.
Some hardware filters require all frames that they will use for output to be defined in advance before filtering starts. For such filters, any hardware frame pools used for output must therefore be of fixed size. The extra frames set here are on top of any number that the filter needs internally in order to operate normally.
This field must be set before the graph containing this filter is configured.
