| 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).

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.
