1 Work with MIPI Camera OV13850 Under Linux
Hardware Setting:
The present Linux kernel only supports MIPI-CSI1 so a camera module can only be connected to a MIPI-CSI1 port and here is the hardware setting:
FriendlyELEC provides a test script "gst-camera.sh" to test a camera's functions. You can run it in a commandline to test picture taking and video recording. You can install the script by running the following command:
sudo wget http://112.124.9.243:8888/rk3399/gst-camera.sh -O `which gst-camera.sh`
1.1 Options in "gst-camera.sh"
Options Comment --index or -i Camera's index, it can be either 0 or 1. When two cameras are connected to a board you need to specify 1 to access the second camera. --mode or -m Camera's resolution. For example if a camera's resolution is 720P 30FPS you can set width=1280, height=720 and framerate=30/1 --action or -a Specify an action, it can be "preview" to preview, "photo" to take a picture or "video" to record video --output or -o Specify an output file to save a picture when taking a picture or video file when recording video --verbose or -v If it is specified as "yes" it will output the complete command when "gst-launch-1.0" is called
1.2 Usage of gst-camera.sh
- Preview
gst-camera.sh --action preview- Picture Taking
You can run the following command to take a picture and save it as a "1.jpg" file,
gst-camera.sh --action photo -output 1.jpg
- Preview and Record
You can run the following command to preview and record video and save your video to a "1.ts" file. Hardware encoding is activated when it is recording video.
gst-camera.sh --action video -output 1.ts
- Show Complete Command
If you add the "--verbose yes" option it will show a complete gsteamer command.
gst-camera.sh --action video --output 1.ts --verbose yes
Here is the complete gsteamer command you will see:
gst-launch-1.0 rkisp num-buffers=512 io-mode=4 path-iqf=/etc/cam_iq/ov13850.xml \ ! video/x-raw,format=NV12,width=1280,height=720,framerate=30/1 \ ! tee name=t t. ! queue ! kmssink t. ! queue ! mpph264enc \ ! queue ! h264parse ! mpegtsmux ! filesink location=1.ts
