Enclosing class:

avfilter.AVFilter

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" / \ref AVFilterLink.out_samplerates "out_samplerates" and \ref AVFilterLink.in_channel_layouts "in_channel_layouts" / \ref AVFilterLink.out_channel_layouts "out_channel_layouts" analogously. This callback may be NULL for filters with one input, in which case libavfilter assumes that it supports all input formats and preserves them on output.
