Youtube's URL parameters not working properly

I have this URL:

https://www.youtube.com/embed/wU4DgHHwVCc?autoplay=1&start=100&end=120&loop=1&playlist=wU4DgHHwVCc

What I want to achieve:

• keep looping
• auto play on every loop
• on every loop back start from 100th sec and end on 200th sec.

Issue:

On every loop back video starts from 0th sec, instead of what is given at start parameter.

Does anyone know what I am doing wrong?
