FFMPEG - Not finding codec parameters

Question

I\'m trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video: mjpeg).

Answer 1

It may be necessary to specify the input codec for the series of images. Note the -c:v gif addition in the second example, to be placed before the input source:

$ ffmpeg -f image2 -i %03d.gif zzz.webm
# Error: %03d.gif: could not find codec parameters

$ ffmpeg -f image2 -c:v gif -i %03d.gif zzz.webm
# Works! ffmpeg version 2.7
