Hey-o. So, I've actually tested the Linux build on my Pi desktop using an x86 emulation layer...and it actually works compared to some others I've tried. However, I'm not sure about using OBS on my Pi though. In the meantime, I tested it using Discord's screen share (the browser version of Discord, mind you)
My only complaint is that the interface for setting it up is squashed in some places. Plus, it was unclear about using double-click to turn off transparency or even greenscreen, but other than that, this is probably the most optimized pngtuber app I've seen.
To put it simply, I love it! I would also love a native aarch64/arm64 version for those that can't work with a x86_64 emulation layer.
Thanks for an amazing app though. <3
