Ud fra fejl-meddelelsen ser det ud som om der er fejl
i din video-streams frame-rate. Måske video-filen
er korrupt. Kan du spille den med mplayer? Jeg ved ikke 
hvordan man redder defekte video-filer.

Hvilken kommando bruger du? Jeg prøvede og det kører (men
giver en voldsom kompression, vistnok forringet kval.)
Output er forkortet:

# ffmpeg -vf "transpose=1"  -i MVI_9507.avi rotated9507.avi
[...]
Output #0, avi, to 'rotated9507.avi':
