#6387: ffmpeg crashes when pad filter is incorrectly specified

Summary of the bug:
I tried to resize videos using command -vf "scale=800:-1,
pad=800:480:x=-1:y=-1" But height of some videos become lagrer than 480.
So ffmpeg tries to begin encoding, but just crashes. Probably it should
give out error about incorrect parameters, but not crash.
How to reproduce:
{{{

Videos\incorrectly_speci

pad=800:480:x=-1:y=-

[mpeg4 @ 03f75940] Video uses a non-standard and wasteful way to store
B-frames
('packed B-frames'). Consider using the mpeg4_unpack_bframes bitstream
filter wi
thout encoding but stream copy to fix it.
