Introduction
This section demonstrates how to use GStreamer elements for Coral hardware. Contains example pipelines showing how to capture from the camera, display into the screen, encode, decode, and stream.
Pipelines
 | Note: For these pipelines, you can modify the CAMERA, OUTPUT_FILE, HOST and PORT variables according to your needs. |
Display Output
CAMERA='/dev/video1' gst-launch-1.0 v4l2src device=$CAMERA ! "video/x-raw, width=1280, height=720" ! videoconvert ! autovideosink
Video Recording Output with H264 Encodification
CAMERA='/dev/video1' OUTPUT_FILE='my_video.mp4' gst-launch-1.0 v4l2src device=$CAMERA ! "video/x-raw, width=1280, height=720" ! videoconvert ! \ x264enc tune=zerolatency speed-preset=ultrafast ! h264parse ! qtmux ! filesink location=$OUTPUT_FILE -e
Streaming Output with H264 Encodification
- Processing side
