How to do a picklist that depending on the value of another picklist?

const codecToContainerFormatMap = {
  "h264": ["mp4", "mkv", "mov", "avi", "flv", "ts", "webm"],
  "h265": ["mp4", "mkv", "mov", "ts"],
} as const;

v.object({
    codec: v.picklist(["h264","h265"]),
    format: v.picklist(?),
  }),

That would be discriminated union (https://www.totaltypescript.com/discriminated-unions-are-a-devs-best-friend), which can be achieved using https://valibot.dev/api/variant/
