Hello - well, I thought I had a breakthrough moment with a wireless HDMI transmitter/receiver package I got from AliExpress and a cheap HDMI to USB capture card. The idea was to make a wireless workflow for my Canon DSLRs for live streaming events.
Basically, I am able to receive the Live View camera feed on my laptop via my software (OBS) wirelessly as I hoped - great - but I can't see what I am shooting as the Live View goes off on the camera itself when I send HDMI out to the transmitter - which disallows what I'm hoping to achieve as I can't shoot blind.
Is HDMI out screen mirroring totally impossible on anything but a 5Dmk3? Is the only solution to do something like split HDMI and get an external small monitor to mount on the camera? I realize this all sounds like a lot of work, but I really want to use the 550D and 600D bodies I have with my Takumar f1.4 50mm lenses - the bokeh and constant focus pulling just look amazing on a live stream.
