Could I use the features of the GStreamer plugin in C? #83

Hi,

I got this pipeline by modifying the BslBrightness feature in GStreamer: gst-launch-1.0 pylonsrc cam::BslBrightness=1 ! videoconvert ! autovideosink

And I want to define that same pipeline in C: pipeline = gst_pipeline_new ("pipeline"); src = gst_element_factory_make ("pylonsrc", "my-pylonsrc"); g_object_set(src, "BslBrightness", 1, NULL); conv = gst_element_factory_make ("videoconvert", NULL); sink = gst_element_factory_make ("autovideosink", NULL);

but I receive the following error: g_object_set_is_valid_property: object class 'GstPylonSrc' has no property named 'BslBrightness'

Is there any way to modify the Basler camera features from C?

see this example for the access in C. Same folder also has examples for python access https://github.com/basler/gst-plugin-pylon/blob/main/tests/examples/pylon/pylonsrc.c

The camera and streamgrabber features are so called child-properties. You first have to access the "cam" or "stream" property and under these props are the real features.
