Using ffplay in this video you can see the video is choppy due to a low frame rate due to low bandwidth with the USB 2.0 device.
Here are some commands i used in the video;
v4l2-ctl –list-devices
ffplay /dev/video0
v4l2-ctl --device /dev/video0 --all
lsusb -t
v4l2-ctl --list-formats-ext -d /dev/video0
And then to change the video resolution and therefore increase the frame rate followed by a higher resolution but using mjpeg.
ffplay /dev/video0 -video_size 1280x720
ffplay /dev/video0 -video_size 1920x1080 -pixel_format mjpeg
