Image and Video Capture Plugins
For more details, refer to the gst-pylonsrc documentation at
https://gitlab.com/zingmars/gst-pylonsrc/-
. Note that use ‘pixel-format’ property instead of ‘imageformat’ property when
referencing this document.
Notes
:
1. Download and install the ADLINK EVA SDK to access the pylonsrc plugin. For more details, refer to the
ADLINK EVA Installation Guide.
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.

Using
gst-launch
Displaying a pylon video with ycbcr422_8 format.
gst-launch-1.0 pylonsrc pixel-format=ycbcr422_8 ! videoconvert ! xvimagesink

gst-launch-1.0 pylonsrc limitbandwidth=false sensorreadoutmode=fast fps=150 !
videoconvert ! matroskamux ! filesink location='recording.mkv'
Setting the resolution width and height to 960x540 and displaying the pylon video.
gst-launch-1.0 pylonsrc width= 960 height=540 ! videoconvert ! xvimagesink
Centering the pylon video and display.
gst-launch-1.0 pylonsrc centerx=true centery=true ! videoconvert ! xvimagesink
