I'm just starting with ffmpeg, and i can't get any command to run, they all return

"Unable to find a suitable output format for 'i'
i: Invalid argument"

The command was just ffmpeg i StarWars1977.m4v. Does the input file need too be in somewhere specific, or do I need to copy the file path?

I'm trying to extract frames from a video, but it was giving the same error, so i was trying a simpler test.

  • Your question needs a little more information. Do you want to extract certain frames or all of them? BTW, it should always be -i instead of i.

  • certain frames, but i wanted to run the command as a test, because it wasn't working.

  • Welcome! If you ran the command exactly as you have it in the question, you need a hyphen before the i. ffmpeg -i StarWars1977.m4v

This will get you one frame at the one minute mark.
