Hello Beginner here, Started learning and understanding more n more with practice. I have been searching up n down for examples on adding caps in code but after a few days I still don't have a clue. E.g setting width and height, or denoise, detail, brightness, hue, frc-algorithm and the list goes on. My boss has built a UI in html, php; where he has been able to add to inser text or choose from a drop down list options for the pipeline. Looks like this screenshot of my setup: <img src="http://gstreamer-devel.966125.n4.nabble.com/file/t379895/rsz_screenshot_from_2021-03-18_17-24-45.png" border="0"/> My task was to add and integrate those options shown in the image. After choosing those options I then create a xml file, then read that xml file options into variables using an xmlreader. For e.g I know a video source capabilities would include width and height. I know how to add those caps using gst-launch-1.0 or gst-parse-launch what I really wanna know is how do I get that done in code. I don't even have any idea which element has capabilities such as the others shown in the image but for now I'd just like to how to add them in code. I have seen e.g. such as: GstElements *capsfilter; GstCaps * caps; capsfilter = gst_element_factory_make ("capsfilter", "capsfilter"); caps = gst_caps_new_simple ("video/x-raw", "width", G_TYPE_INT, 1920, "height", G_TYPE_INT, 1080, "framerate", G_TYPE_INT, 60, NULL); g_object_set (capsfilter, "caps", caps, NULL); gst_caps_unref (caps); I'd also appreciate any idea or guide on adjusting these in code: denoise, detail, brightness, hue, frc-algorithm, etc <hr align="left" width="300" /> Sent from the <a href="http://gstreamer-devel.966125.n4.nabble.com/">GStreamer-devel mailing list archive</a> at Nabble.com.
