[FFmpeg-user] overlay filter uses unmapped cover image

[Christian Ebert]

Hi,

How do I map the streams so that the overlay filter does not
select the cover image of the input video as overlay?

I thought I had deselected stream 0:2 by specifying -map 0:v:0?
Adding -map 1 also has no effect.

$ ffmpeg -i test.mp4 -i logo.png -map 0:v:0 -filter_complex overlay=main_w-overlay_w-10:main_h-overlay_h-10 test.mp4
