Image and Video Capture Plugins
23
3.1.6 ksvideosrc
This element provides low-latency video capture from WDM cameras on Windows.
For more details, refer to the official documentation at:
https://gstreamer.freedesktop.org/documentation/winks/index.html?gi-language=c
3.1.6.1 Example Using gst-launch
This pipeline shows the video captured from a webcam.
gst-launch-1.0 ksvideosrc num-buffers=1000 ! glimagesink sync=false
3.1.7 hikplugin
This is a GStreamer element that uses Hikrobot's USB3 and GigE vision cameras. When multiple cameras are
available, use the camera property to specify the specific camera for image capture.
Notes
:
1. Hikrobot MVC can access other vendor USB3 cameras with the HIK USB filter driver.
2. The downstream elements may waste a lot of time handling frames. If the camera's frame rate is too fast, the
pipeline will drop a lot of frames, resulting in rendering delays. However, the rendering and AI inference
performance of each platform are not the same. It is recommended to reduce the frame rate of the camera
source or image resolution to make the rendered screen output smoother.
3.1.7.1 Examples
Using
gst-launch
This pipeline shows the video captured from a Hikrobot camera.
gst-launch-1.0 hikplugin ! videoconvert ! glimagesink
Use the pixel-format property if the camera module supports other pixel fomats. The example is YUV422_8_UYVY.
Gst-launch-1.0 hikplugin pixel-format=YUV422_8_UYVY ! videoconvert ! glimagesink
This pipeline use BayerBG8 format to display a Hikrobot video.
gst-launch-1.0 hikplugin pixel-format=BayerBG8 ! bayer2rgb ! videoconvert !
glimagesink
Use the camera property to set the camera ID if the system has multiple camera modules.
gst-launch-1.0 hikplugin camera=0 ! videoconvert ! glimagesink
