"No accelerated colorspace conversion found from yuv420p to rgba."

[DSohl]

Hi, not sure if this is a matter to discuss here or on the ffmpeg forums, but I'm curious why each time I digitize or even run a passthrough, I get a large chunk of "No accelerated colorspace conversion found from yuv420p to rgba" notifications before the vrecord monitoring screen opens. It does not seem to impact the digital copy, but I'm curious if my processes could be more efficient?

It looks like so:
