ffmpeg not reconnect when youtube URL is expired

[fanadol]

Hi, so i have been using your package for build my discord bot. Its great thank you.

I found this problem when i playing around with my bot. When playing music (from youtube using ytdl package) its stop in the middle of the song. The error said it's EOF. But the song is not finished yet.

When i print the encodingSession.FFMPEGMessages() its shows something like this:

When i try to google this error, it's turn out that the youtube URL was expired. So the ffmpeg immediately return EOF.

The specified session has been invalidated for some reason.

I am able to solve this issue (maybe) to add reconnect flag in ffmpeg command. I will try to link my PR to this issue.

Thank you.

Hi,
I just wanted to say that the pull request by fiwippi is exactly the change that resolved this problem for me.
So merging it should fix the whole EOF timeout issue.
Thanks for the great package! :)
