First: I don’t think play a youtube video using webview is the best choice.
Second: If all you want is that the video start to play from the very same seconds, just save the time in a variable and when you have to play the video again, set the video in the other arrangement to start on xx seconds.
But answering your question directly, I don’t know if it is possible, and I don’t think anyone knows the answer. You will have to try yourself or pay someone to try for you.
