Set Resolution

Taking port 0 as an example, you can enter the following commands to set the resolution to 1920*1080.

# v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='NV12'

Preview camera

Taking port 0 as an example, you can set the preview of the camera video by using the following command.

# export DISPLAY=:0.0
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/aarch64-linux-gnu/
gstreamer-1.0
#gst-launch-1.0 v4l2src device=/dev/video0 \
! video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1 ! xvimagesink

Camera photography

Taking port 0 as an example, the following command can be used to take a camera photo, and the save address is picture.jpg in the current directory.

# gst-launch-1.0 v4l2src device=/dev/video0 num-buffers=10 \
! video/x-raw,format=NV12,width=1920,height=1080 ! jpegenc \
! multifilesink location=picture_%02d.jpg && \
rm picture_0{0..8}.jpg && mv picture_09.jpg picture.jpg

Camera screen recording

Taking port 0 as an example, the following command can be used to record videos with the camera, and the save address is video.mp4 in the current directory.

# gst-launch-1.0 -e \
v4l2src device=/dev/video0 \
! video/x-raw,format=NV12,width=1920,height=1080,framerate=25/1 \
! videoconvert \
! x264enc bitrate=5000 speed-preset=ultrafast tune=zerolatency \
! h264parse \
! mp4mux \
! filesink location= video.mp4
