Streaming from a modded Switch
Probably too far-fetched, but curious anyway since this would make things a lot easier.
Recently got a modded Switch with a chip and it's got custom software with this Tinfoil app on it, and I was wondering if it could be possible to somehow stream to Twitch/YouTube directly, without a capture card, using an app that would work only with a modded version of the console.
You can unlock the browser and maybe do it that way. If you just want YouTube, the switch has a YouTube app, no need for homebrew there.
If you want to go full out, you can install a second OS like GNU/Linux or Android and stream with that OS.
I think what you mean is streaming from YouTube, OP wants to livestream to YouTube
BAM!
You might be right, oopsie
That's definitely going to make the Switch struggle to maintain its framerate.
I wouldn't be so sure about that. The Switch records a 720p30 video all the time for its 30s replay functionality that is on by default.
At least theoretically, capture and encoding themselves shouldn't cause any more performance issues than a stock Switch already has (unless you try to stream and have the replay buffer ofc.) and sending a bunch of video data over a network isn't very intensive.
something like this? https://github.com/exelix11/SysDVR
Just Google "stream to YouTube from switch" there's a built in option. Here's a screencap of the top result.
I don't think that what you want exists. The best I can offer is SysDVR, which streams video to a PC and from there you could livestream that.
Alternatively, you could try your luck asking on GBAtemp and see what they know.
