The protocol is one thing, the other nearly more important one is the bandwidth/encoding for each platform. On YouTube you may want to put out a high-res/high bitrate version and let YouTube handle the churning down to lower resolutions. On Twitch, unless you're a partner, you want to pick a low enough bitrate, otherwise your viewers will be hit with a high bitrate and some end up unable to watch the stream. So lots of reencoding happening on the fly, which is why I know of some streamers using dedicated streaming computers, that take the OBS stream as input, but I don't know what software they use to distribute it.
