ffmpeg isn't accepting "%d" format?

So, I have a directory full of files named motor_animate_000.gif, motor_animate_001.gif, etc.

I run:

ffmpeg -r 30 -i motor_animate_%03d.gif -r 30 motor.mpg

I expect to get a file called motor.mpg, but instead I get the usual bunch of printout, ending with:

motor_animate_%03d.gif: No such file or directory

What? This worked in Ubuntu 14.04, but doesn't work now. What I'm doing appears to be consistent with the ffmpeg man page. I'm now officially clueless. Thanks in advance.

Here's what I get when I try the alternate suggested below:

tim@Servo:~/Documents/Movies/dcmotor/animation$ ffmpeg -f image2 -framerate 30 -i motor_animate_%03d.gif motor.mpg

The gif demuxer does not support a series of input files. You'll need to manually tell it to use the image file demuxer instead:

ffmpeg -f image2 -framerate 30 -i motor_animate_%03d.gif motor.mpg

  • The image file demuxer uses -framerate instead of -r.

  • You don't need to declare frame rate twice if you want to output to be the same as the input, so I removed the output -r.
