This was actually NV12, couldn’t even get YUYV to record at all with gstteamer this is. One difference is that this is from a webcam source (which outputs both NV12 and YUYV), also haven’t tested using mpi_enc_test which I’m guessing is from here?

I’ll have to test it to see if there is any difference.
