--frame-format error

[RoyZhDec]

It runs correctly when I use xvfb-run -s "-ac -screen 0 1280x1024x24" ffmpeg-concat -o all_in_one.mp4 -T trans_temp.json 1.mp4 2.mp4 3.mp4 4.mp4
However, in order to avoid large storage costs, I set -f jpg, I get errors like these:

xvfb-run -s "-ac -screen 0 1280x1024x24" ffmpeg-concat -o all_in_one.mp4 -f jpg -T trans_temp.json 1.mp4 2.mp4 3.mp4 4.mp4

did you find any solution for this? I'm also facing same problem for png frameFormat.
