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). A Google search did not bring much up that was useful.

The images reside in the /tmp directory with names such as img001.jpg and img002.jpg.

Any ideas?

Thanks -Tanner

Baseline JPEG doesn't support 16-bit precision, but JPEG 2000 does. — tripulse, Feb 17 '20 at 14:13

What ffmpeg is actually trying to tell you is, that your file has extension of jpeg, but the file actually is bmp or some other format.

Make sure that the file is encoded in jpeg and the problem will disappear.

It may be useful to do a sanity check of your images by running the command with just one: `-i /path/to/single_image.jpg`, as improperly setting up the input list can result in red herrings, which may have landed you on this post. `-i` and the related `image2` flags, `pattern_type`, `start_number`, etc, can be a little confusing initially, see https://ffmpeg.org/ffmpeg-formats.html#image2-1 – dave thompson Jun 16 '22 at 16:51

Some people here say that it is because the mjpeg codec cannot really be found. They suggested installing it from the source. I feel that it is more likely that the mjpeg is not installed. I feel there are two solutions for this.

You can try to install that codec and see if it helps MJpeg Download For Win
You can try forcing the ffmpeg to export it into a different codec Try: ffmpeg -f image2 -i /tmp/img%03d.jpg -vcodec mpeg2video video.mpg

I compiled and installed it from source and I still get the error. It seems as though the MJPG is not the same thing as is Windows only. I'm compiling and executing this on a Ubuntu machine. – Tanner Smith Sep 17 '10 at 16:39
I would try forcing a different codec using -vcodec, at least to see if it works. – Jimmie Clark Sep 17 '10 at 20:10
Ill do some testing and get back with you. – Jimmie Clark Sep 18 '10 at 20:18

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

This is the first place where I saw that you can specify the input codec to use. It solved my similar problem. – hazzey Aug 02 '16 at 02:53

There can be several issues of FFmpeg not being able decode your image. Other answers aren't insightful on this issue, none addressed the issue of unsupported coding algorithms.

The JFIF standard allows for Huffman or Arithmetic coding (Annex B.1.1.5). FFmpeg's implementation however, doesn't consider for Arithmetic coding, it outputs similar error messages to yours.

# query the coding type
exiftool image.jpg | grep -i "encoding"

This is the correct approach, I am able to identify the image have unsupported encoding (or my case not showing any coding algorithm) and then make it `Huffman`. – hakuna1811 Nov 10 '19 at 02:18
**ImageMagick** supports other coding algorithms rather than only Huffman. – tripulse Nov 10 '19 at 02:30

Try this:

ffmpeg -f image2 -i /tmp/img%03d.**jpeg** video.mpg

Actually, I have a similar problem here .. (and solved).

I have a sequence of images named file-001, file-002 etc (.tiff files). I forgot to give an extension ".tiff", so I got an error when I ran ffmpeg command

ffmpeg -f image2 -i file-%03d.tiff video.mpg

It was solved when I renamed the files by adding ".tiff" extension.
