Nothing at all, not even a console message?

Please show us the complete, uncut console output. Furthermore, when
encountering issues, please try to use the latest version of ffmpeg.
Your version (or its branch <= 3.1) is probably over a year old.

It also looks like your filter syntax is extremely borked. Unless I'm
too tired, it looks like you are using filter_complex syntax with
"-vf", and the chain is totally incorrect. Should probably be something
like:
  -filter_complex "scale=1280:-1[in]; movie=0.png:/root/logo.png [logo]; [in][logo] overlay=main_w-overlay_w-50:50 [out]" -map "[out]"

(Note, apart from the changes chain, that "0:png" is probably a typo, meant to be
"0.png"?)

Thanks,
