Maybe vmem does not work either. That changes nothing to the fact that
dummy does not work properly for what you are trying to do.

This is about libvlc as a whole, not the MEDIA PLAYER object. Besides, VLC
does NOT have a background snapshot feature, only an interactive snapshot
feature. And if it does have a background snapshot feature that I a unaware
of, it is definitely not in the video output core.
To dump frames programmatically, there is vmem (already exposed) or
transcode + custom sout (not exposed so far).
