I finally found out what the error code means:

{AVERROR_INVALIDDATA, "INVALIDDATA", "Invalid data found when processing
input" }, // -22

which seems to be identical to the -1094995529 error (although I can produce
both errors in different situations so I don't know how they differ)

What is wrong with "movie=logo.png [logo];[in][logo]
overlay=10:main_h-overlay_h-10 [out]"?
