I came to see a question on Stack Overflow two days ago that had a link to a tutorial on vlcj, but the link that the question as well as an answer used, are no longer available, but are dead. I edited the link on the question as well as the answer, updated it to the newer one. But the edits weren't applied, neither to the question, nor the answer.
Are we not allowed to edit links contained in the question or answer, even if the links are no more available and I have the new link.
I had mentioned in the details, the old link is no longer available, here is the newer one.
What if someone close to solving the problem just misses something important just due to the dead links?
Are we not allowed to edit the links?
