问题
Youtube has a feature when you can embed a video and mark start and end time with it. It displays a frame on the seek bar and video starts from the starting mark and ends at the ending mark.
It stopped working a few weeks ago.

Here is a url that I am sure was working before.
Now it starts from point marked in the url, but it does not end at the ending mark.

It just worked well for me.
I added the autoplay=1 parameter in the URL you provided and the video actually starts and ends at the indicated positions.
Here is the modified URL:
