The new request_new_pad_full vmethod provides an additional caps field, which allows elements to take better decision process. Also, add a gst_element_request_pad() function to allow developers to be able to specify which pad template they want a pad of. Convert gstutils to use that new method instead of the old one when more efficient. 2013 ... spiritual nature bible verse However, if I use Gst.Element and initialize the pads myself. This problem goes away but BaseTransform is more convenient to use.. Is the example outdated or I have incompatible versions of GStreamer packages? Thank you in advancePads without pad templates can be created with gst_pad_new () , which takes a direction and a name as an argument.
