lavfi: deprecate avfilter_graph_add_filter().
...
Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.
2013-04-11 20:36:42 +02:00
bc1a985ba0
lavfi: replace avfilter_open() with avfilter_graph_alloc_filter().
...
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.
