This is exactly how I started off.

I recommend:
- Read https://ffmpeg.org/developer.html, especially
- Subscribe to the ffmpeg-devel mailing list.
- Observe that mailing for some time.
  - Understand what is expected from a contribution, and what the
    pitfalls are. (Bad commit messages, incomplete context, bad code,
    bad coding style, malformed patches, answering to the wrong thread,
    top-posting, ...).
  - Understand how the review process goes.
- Pick your favorite nit. I started off with documentation buglets
  (spelling errors, missing documentation on options) and small code
- Also check trac (the bug tracker) for "easy" issues you may want to
  help solving, or even just reproducing:
  Also check there to see whether your favorite nit is already
- Check the ffmpeg-devel archives, whether someone has already
  attempted what you are trying.
- Enjoy. :)
