# Warning, this cog sucks so much but hopefully it works and doesn't break the bot too much.
# Just lazily edited old code and bodged it into this one.
# There is redundant code here that if removed would make it easier.

# Edit, cleaned up a lot more. But it still is a bit dodgy, when discord allows for the video object to be used in embeds, then we need to convert the cog to output embeds.
