Your program reads the first file whole and feeds it to the graph, then
reads the second file whole and feeds it to the graph, and only afterwards
read from the filter. That will require enormous amounts of memory, and
possibly fail since libavfilter is not designed for data accumulation in the
middle of filter graphs.

When working with a graph with several inputs, you need to read from the
output, and if it fails due to input being required, add to the correct
input (not both!).
