ffmpeg gives error "Invalid data found when processing input" when concatenating jpg files

I have a server running Ubuntu 18.04 LTS.
I have a directory with a number of jpg files taken with an IP camera. I am trying to concatenate the jpg files into a single mpg video file using ffmpeg with the following command:

ffmpeg -f concat -i /tmp/myjpegs /tmp/myvideo.mpg

I get the error message:
/tmp/myjpegs: Invalid data found when processing input

There is nothing else in the /tmp/myjpegs folder apart from the sequence of jpg files.

This the the output from the command:

libavutil 55. 78.100 / 55. 78.100
libavcodec 57.107.100 / 57.107.100
libavformat 57. 83.100 / 57. 83.100
libavdevice 57. 10.100 / 57. 10.100
libavfilter 6.107.100 / 6.107.100
libavresample 3. 7. 0 / 3. 7. 0

Tip: You can also try this.

cat /tmp/myjpegs* >  /tmp/myvideo.mpg

Open in new window

As I recall, .mpg containers can be directly concatenated.

I'd try this first + see if it works. I did some looking + couldn't find a definitive answer online + I don't have any .mpg footage available to test.

My suggestion is you try the Linux cat command first + see if that works.

Thanks, that was the key to the solution. Now that I have created a text file containing the names of the jpegs all works fine. (I had to add -safe 0 to the command line).

BTW. cat jpegs to mpg didn't seem to work.

Cheers for the help.

Glad you got this working!
