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 frame= 2 fps=0.0 q=0.0 Lsize=N/A time=00:00:00.08 bitrate=N/A video:205kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown Conversion failed!
