Change #278880

Comments

avfilter/af_afir: clamp initial ir selection
the ir option may exceed nbirs because its static range is independent
of the configured number of impulse responses. init() only clamps
prev_selir, leaving selir able to index ctx->inputs out of range.

with the default nbirs=1, afir=ir=1 reads ctx->inputs[2] and crashes.
clamp selir like process_command() and add a fate test.
