Hi, i try both devices (USB Video grabber with HDMI convert to CBVS or this HDMI USB Video grabber) and on all of this deivices i see green line. HDMI convert to CBVS looks works, i check it in my TV.
This is my command to take screenshot at Raspberry pi ZERO
hyperion-v4l2 -v PAL --crop-left 16 --crop-right 20 --crop-top 5 --crop-bottom 46 -f 2 -s 0 --screenshot --input 0
Some idea?
thanks
