I am trying to convert .mov videos to mp4(should be playable in iPhone) using ffmpeg.I am using Linux CLI. I have tried the following command:

-i source.MOV -s qvga -b 384k -vcodec libx264 -r 23.976 -acodec libfaac -ac 2 -ar 44100 -ab 64k -vpre baseline -crf 22 -deinterlace -o output.mp4 

I get the output

ffmpeg: unrecognized option '-o'

Please clarify your question, what have you tried that didn't work, are you writing a program to do this or just trying to it manually? – jrturton Nov 21 '11 at 12:40

I don't think this is a question for SO, it is a support question for ffmpeg. – jrturton Nov 21 '11 at 12:47

For this kind of tasks, I switched from FFmpeg to HandBrakeCLI:

HandBrakeCLI -i source.mov -o destination.mp4 --preset='iPhone & iPod Touch'

I've used this command in CLI ,its working ,but converted videos playing only seconds when the original video have long way to go – Rinto George Dec 5 '11 at 5:16

There is no -o to output a file. Just remove it and pass the desired output filename as the last argument.
