Comment:

 I'm seeing this very same issue. Only though, when I am getting a still
 frame. It seems also affected by -vframes (if this flag is in front of
 -vf, it errors everytime). It appears if you take transpose out, it's
 fine. I've tried putting -vf filters in [in] [out] as well.

 Command is:-


 {{{
 ffmpeg -i /var/input/video.wmv -ss 20 -s 480x272 -vf
 "transpose=1,pad=854:480:291:0" -vframes 1 /var/output/still.jpg <
 /dev/null 2>&1
 }}}
