A Raspberry PI should be fine for direct play, but it doesn’t really have the processing power to transcode. Check to see which mode you’re in.
If you want the ability to live transcode, you’d probably have better luck with an old laptop or PC with a dedicated GPU (Even the lowest end ones have the same video encoding hardware in each generation, I use a GTX 1050).
One or two models have increased in accuracy. Meanwhile all the grifters have caught on and there’s 1000x more AI companies out there that are just reselling ChatGPT with some new paint.
