I'm attempting to take a set of images taken at 1-second intervals to form a timelapse video. I figured this would be easy with ffmpeg, but i'm running into cryptic errors.
All the images are yuv420 jpegs, taken from an android camera. They're saved as individual jpegs in a folder, they're all identically sized and formatted. They are named as a sequence of 7-digit names, starting at zero (so "0000000.jpg" to "0001000.jpg", as an example).
This is my string (folder names redacted for clarity):
avconv -r 1 -f image2 -i %07d.jpg -vcodec libx264 -crf 18 -preset slower video.mp4
Seems great, i see plenty of posts from people who say that works for them.
However ffmpeg gives me this (bold indicates error)

The import lines (which show up in red) are the ones that say "[mjpeg @ 0x233aea0] overread 8".
This makes me think that perhaps it's trying to read the images as motion jpegs instead of plain jpeg files, and is failing somehow. I've tried with/without "-f image2", with the same result. And i've also tried using avconv, with the same result.
I should note that the images are valid, and if i convert them all to *.png (a costly and time-consuming process) the whole thing works. But i'd prefer to just be able to use the jpegs, without an intermediate conversion. After all, that's what ffmpeg is for, transcoding.
Does anyone have a good way to convert *.jpg to video using ffmpeg?
