I think we are talking about different things.

I am talking about the p_input->ppsz_options array, which gets larger and larger if you continue adding distinct „start-time=xy“ options. This is a fact, and please look at the code for that. And this array is saved to the media library, which was the reason to do the patch.

You are probably talking about how this array is internally handled, and how the values are parsed and used. Of course you can only apply one value to one option. But this was never my point.
