ffmpeg: Image2 => Error while opening encoder

Question

I get the following error ffmpeg.

Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

ffmpeg -f image2 -i %05d.jpg -vcodec libx264 foo.mp4

I'm pretty sure I've used this exact command before and it's been fine. This is my terminal output. Any help would be appreciated.

$ ffmpeg -f image2 -i %05d.jpg -vcodec libx264 foo.mp4

You have to crop the input image so that the resulting width and height was divided by 2

Crop filter: -vf "crop=in_w-1:in_h"

$ ffmpeg -f image2 -i %05d.jpg -vf "crop=in_w-1:in_h" -vcodec libx264 foo.mp4

UPD

We can write the formula for the general case, which leads to the even sides

$ ffmpeg -f image2 -i %05d.jpg -vf "crop=((in_w/2)*2):((in_h/2)*2)" -vcodec libx264 foo.mp4
