Thank you very much !

Media players cannot generally open multiple files in a single stream. Quite justly, they go for the simple approach and only read one file from stdin. When they're finished, they're closing the socket - that's why youtube-dl raises ValueError: I/O operation on closed file.

See #628 for an API that would allow playing videos while downloading them. I'm currently working on that and expect it to be finished in a week or so. For now, I'm sorry, but I don't know of any player-independent way to play multiple video files from one stream. Feel free to comment or suggest code though.
