Hi Jack,
"no luck" is a very short error description. Please show us a (real,
complete) command line and the full, uncut console output.

Please realize that ffmpeg's console output contains a lot of useful
information, and it should even tell us what was going wrong. There's
no general answer to your question, as it depends on a few things.
