Mobile RTMP broadcasting into OBS
It would be amazing if you could broadcast directly from your phone using the twitch app into obs so you have your overlays alerts ect. While keeping out 3rd parties like Streamlabs from charging to keep your stream online instead you do that yourself ( I mean actually do it yourself ) using your preferred streaming software. While your connection might be intermittent the stream stays on and maybe has some type of overlay in the background while you're trying to reconnect. I myself really like doing IRL streaming though the only issue with having spotty coverage in some areas is that it drops the whole stream. While sure disconnection protection works it is only for 90 seconds. I know that more recently twitch has introduced a way to get video feed into obs using guest stars so this is 1000% possible with the technology that is already available.
On Android try IRLPro app. On iOS try Larix broadcaster, they do what you ask. There's a super helpful discord community for this as well: https://discord.gg/QTwmXmYP
