When I use:
it fails and returns -22. The documentation states that if it fails it
returns a negative AVERROR code, but I can't find documentation anywhere
that tells me what the code -22 actually means.
I can successfully parse the graph beforehand:
filter_descr = "movie=logo.png [logo];[in][logo]
avfilter_graph_parse(filter_graph, filter_descr, &inputs, &outputs, NULL)
but I avfilter_graph_config does not work.
As a side note, it does work if I use
filter_descr = "color=red at 0.2:720x480:10 [color]; [in][color] overlay [out]"
I have made sure that I have enabled the overlay and movie filters when I
What does the return value -22 mean? For what reasons will
avfilter_graph_config fail when using that filter_desc?
