Comment (by llogan):
Two issues:
Your `ffmpeg` is old. Only recent builds from the git master branch are
supported here due to the level of development that occurs.
[https://johnvansickle.com/ffmpeg/ Download] a build or compile.
You need to add `-frames:v 1` to output a single frame. Otherwise use a
pattern, such as `output_%03d.jpg`, as specified in the error message.
