public static class avfilter.AVFilter.Query_formats_AVFilterContext
extends FunctionPointer
Query formats supported by the filter on its inputs and outputs.
This callback is called after the filter is initialized (so the inputs
and outputs are fixed), shortly before the format negotiation. This
callback may be called more than once.
This callback must set AVFilterLink.out_formats on every input link and
AVFilterLink.in_formats on every output link to a list of pixel/sample
formats that the filter supports on that link. For audio links, this
filter must also set @ref AVFilterLink.in_samplerates "in_samplerates" /
