I feel like this is a necro post, Hank lol, but it was never addressed, so I’ll go at it too
I agree with Hank. Podmins often don’t have a lot of storage space to handle files like these. In just three weeks of my server being online I have over 450 members (chances are like 1/6 of them are actually active), but that’s still a lot of people! Imagine if every one of them uploaded a funny 15 second 10MB video? That’s 4GB of space in just one day. Imagination makes me believe that this would absolutely demolish even the best share space.
Instead, I recommend using cloud services like dropbox and/or google drive. If the video is shared publically, perhaps Diaspora would be able to ‘load’ the video into a player and play it remotely rather than actually store the file?
This would have to be coded and managed properly though, because if you have 450 users all watching videos during lunch time, there’s a good chance your server could DDOS itself.
