>Got error when post-instantiating video: Unsupported video codec type H263 ruffle.js:1
nice, updated ruffle and it works
nevermind, it's really slow
plays smooth on https://ruffle.rs/demo/
hm, how odd, now it's smooth. maybe there's something wrong with my configuration
You can try using the flash projector https://www.adobe.com/support/flashplayer/debug_downloads.html
Ruffle still has some problems with certain flashes
The appeal of flash is that it runs in a browser. Having a standalone player defeats it's utility.
