ffmpeg to save captured stream as uyuv422 ?

[chconnor]

I'm using this to capture from my Hauppauge USB-Live2 and it works well (so far):

ffmpeg -f v4l2 -i /dev/video2 -c:a copy -c:v copy -r 30/1.001 output.avi

...the card is outputting YUYV422 by default, but Davinci Resolve can only read UYVY422, so I'm trying to save the stream in that format, but no matter where I stick a "-pix_fmt uyvy422" it doesn't seem to work with that command line... perhaps because the "-c:v copy" ignores such settings?

Any tips on how to get this done? Thanks!

"You can't change pixel formats when using -c:v copy. Change to -c:v rawvideo." Would be nice if there was a warning.
