Canon EOS M Live View issue with YUV422 + Elgato HD60S+

[MaxWinters]

Hello!
I love Magic Lantern.

I am having some issues getting this to work. What I'm trying to do is connect a Canon EOS M mirrorless DSLR to an Elgato HD60S+ and then to a PC with the hopes and dreams of using the DSLR as a web camera.

However, I have now read that the HD60S+ does not support YUV422 (YUV 4:2:2) and I am pretty sure that the Canon EOS M outputs using this codec. Is it possible to change HDMI output on the canon?

Is there any way around this issue? Any help appreciated, even if you're just asking more questions.

Thanks again for Magic Lantern!
