opencv: dewarp not found
On both a Windows (10 64bit, installed from .msi binary) and Linux (Raspbian Lite, installed from APT) system, after installing Gstreamer v1.10, 1.12.4, and 1.14.4, I am unable to use the dewarp element included in the opencv plugin. The release notes state that dewarp should be in all of those versions, but when using it I am met with
WARNING: erroneous pipeline: no element "dewarp".
gst-inspect-1.0 dewarp also says the element does not exist. I have not tried building from source yet, but it should be included.
