Well, if returning YCC as YCC is unacceptable, and converting YCC to RGB is
unacceptable, I believe your only choices are:

  1. Try to convert YCC to Y'CbCr ignoring the gamma curve, which will return
     images that look wrong and cannot be repaired by reasonable means.
  2. Return YCC mislabeled as something else, which will look even more wrong.
  3. Don't include PhotoCD support in FFmpeg.

I don't know if any of these options are acceptable to you.
