how to use gst-plugin-pylon construct gstreamer project in c++?

[Junkai-Liu]

hi,can you provide some examples to demonstrate how to use cmakelist to build c++projects?

As a first start two links;

One example to use cmake for Gstreamer is here: https://stackoverflow.com/a/74038236

The plugin can be used like any other Gstreamer plugin. We have some examples on how to use it programmatically here: https://github.com/basler/gst-plugin-pylon/tree/main/tests/examples/pylon

Thank you very much for your help, I would like to ask if this plugin can start the camera supported by the pylon package, can it take up less CPU resources than calling the pylon C++ interface directly?

[thiesmoeller]

The gstreamer pylon plugin is a based on the pylon c++ SDK. So what pylon supports, this plugin can also Support in principle ( In the limits of Gstreamer capabilities)

On what platform and with which camera interface do you observe too much CPU ressources used ?

[Junkai-Liu]

I'm running a gige protocol based camera on the xavier platform and it takes 30% of the cpu. Can I reduce it to around 10% if I use the gstreamer plugin?

@Junkai-Liu, important factor in gige performance is the size of the network packet, that are send.

To configure your host:

• https://docs.baslerweb.com/network-configuration-(gige-cameras)#changing-the-network-adapter-properties-linux To configure your camera if you can receive e.g. 8192 byte per packet from your network settings:

gst-launch-1.0 pylonsrc cam::GevSCPSPacketSize=8192 ! videoconvert ! autovideosink
