Description of your issue, suggested solution and other information

It seems that when using youtube-dl to download videos that were recently streamed live, it results in an HTTP Error 404. The video resulting in the error above, found at this url, was streamed live approximately 1 hour before attempting to download it which consistently produced the error. However after spending some time searching for a solution and retrying the same command, it worked like a normal video. My best guess would be some caching or processing of the live video on Youtube's end before it is available for programs like youtube-dl to download, however I was able to watch the video on Youtube's website while the problem occurred. Unfortunately I don't know enough about youtube-dl's algorithm to comment on why this may have happened.

Due to the strict timeframe of this problem, it may be difficult to reproduce and it is trivial to solve considering the download worked for me after some time passed. However I am documenting it here for the sake of completeness in case some developer decides to take a look, so that perheps others may benefit.

Thanks for the report. There are already quite a few reports about issues on just-ended live streams, and there's also a generic proposal for handling such problems. See #3721.
