First the general questions: Why are you using -analyzeduration and -probesize? They are often needed for program streams, transport streams or flv files, they should not be needed for mp4. Why are you using "-an -f rawvideo -vcodec mjpeg"? The file extension ".jpg" is supposed to set all three for you. More specifically for your issue: Whatever you are trying to achieve with -itsoffset, I don't believe that it is supposed to work in your command line. Try either the input option -ss or the output option -ss (you generally want the input option). > ffmpeg version 2.5.3 Copyright (c) 2000-2015 the FFmpeg developers Note that only current FFmpeg git head is supported on this mailing list.
