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
