Hello folks,
I am running Zybo Z7-20 Pcam petalinux project on Zybo Z7-20 board.
From README.md file below command will create 14 image files in current directory
yavta -c14 -f YUYV -s "$width"x"$height" -F /dev/video0
when we test similarly our log stucks as per below
root@test0:~# yavta -c1 -f YUYV -s "$width"x"$height" -F /dev/video0 Device /dev/video0 opened. Device `video_cap output 0' on `platform:video_cap:0' is a video output (without mplanes) device. Video format set: YUYV (56595559) 1280x720 field none, 1 planes: * Stride 2560, buffer size 1843200 Video format: YUYV (56595559) 1280x720 field none, 1 planes: * Stride 2560, buffer size 1843200

when we run media device information command(media-ctl -p)
we get following log
root@test0:~# media-ctl -p Media controller API version 4.9.0
