What am i doing wrong?
Want to make a sequence of .jpg images into a video using ffmpeg.
Always get the error:
[image2 @ 0x562a4b827a00] Could find no file with path 'wsct%04d.jpg' and index in the range 0-4
wsct%04d.jpg: No such file or directory

Files in one directory, file sequence starts with wsct1147.jpg and ends in wsct2125.jpg
Numbers are all sequential; none missing.

ffmpeg command run in the image file directory

command run:
ffmpeg -framerate 25 -i wsct%04d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p test.mp4

using command line under Ubuntu 18.04.03latest?d=yIl2AUoC8zA latest?i=l6Ce7q6GN-c:lywKXf1nGek:F7zBnMy latest?i=l6Ce7q6GN-c:lywKXf1nGek:V_sGLiP latest?d=qj6IDK7rITs latest?i=l6Ce7q6GN-c:lywKXf1nGek:gIN9vFwl6Ce7q6GN-c
