  • Reboot the system.
sudo reboot

Test the video

yavta

cd ~/TC358743-Driver/yavta/yavta/
./yavta --capture=1000 -n 3 --encode-to=file.h264 -f UYVY –m -T /dev/video0
The codes will capture 100 framerates and save them to file.h264 file, you can use vlc tool to play the file

gstreamer

  • Install the tool
sudo apt install gstreamer1.0-tools -y
  • Collect video:
gst-launch-1.0 -vvv v4l2src ! "video/x-raw,framerate=30/1,format=UYVY" ! v4l2h264enc extra-controls="controls,h264_profile=4,h264_level=13,video_bitrate=256000;" ! "video/x-h264,profile=high, level=(string)4.2" ! h264parse ! queue ! matroskamux name=mux ! filesink location=file.mkv

Recording

  • Check the audio devices with arecord -l command.
**** List of CAPTURE Hardware Devices ****
card 2: tc358743 [tc358743], device 0: bcm2835-i2s-dir-hifi dir-hifi-0
[bcm2835-i2s-dir-hifi dir-hifi-0]
Subdevices: 1/1
Subdevice #0: subdevice #0
Note: Card 2 is the ID of the soundcard
  • Record the audio and save it as wav file
arecord -D hw:2 -d 25 -f cd test1.wav

Note: where hw:2 is to set the sound card device, it needs to match the actual sound card number, otherwise the audio information cannot be collected normally.
