I have fixed the command as below:
ffmpeg -i apple.mp4 -ss 00:00:4 -vf scale=241:164 apple5.png -y
But I still receive the below warning, the file get created through but I do
not understand the warning.
[image2 @ 0xaf70fc0] Could not get frame filename number 2 from pattern
'apple5.png' (either set updatefirst or use a pattern like %03d within the
filename pattern)av_interleaved_write_frame(): Invalid argument

you definitely have an incorrect command line syntax. the scaling
details should be preceded by the -vf switch (as this is a video
filter), otherwise ffmpeg would consider that argument as the output file.
the error message really gave you the hint to the problem.
ffmpeg -i apple.mp4 -ss 00:00:4 -vframes 1 *-vf* scale=241:164 apple2.png
