            Bug ID: 796240
           Summary: gst-validate-1.0 ignores errors in pipeline element
                    parameters
    Classification: Platform
           Product: GStreamer
           Version: 1.14.0
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-devtools
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: meinemailingliste2 at online.de
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When calling gst-launch-1.0 with a wrong parameter (have a look for abc=456):

# gst-launch-1.0 v4l2src
device=/dev/v4l/by-path/platform-capture-subsystem-video-index4 io-mode=dmabuf
abc=456 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=50000/1000 !
fakesink silent=false

then I get a warning

WARNING: erroneous pipeline: no property "abc" in element "v4l2src0"

and execution is aborted.

Doing the same with 

# gst-validate-1.0 --set-scenario testpauselang v4l2src
device=/dev/v4l/by-path/platform-capture-subsystem-video-index4 io-mode=dmabuf
abc=456 ! video/x-raw,format=NV12,width=1920,height=1080,framerate=50000/1000 !
fakesink silent=false

the execution just runs without any comment nor notice.
No abort of the program.

Should not at least a test tool check the validity of the pipeline
like gst-launch-1.0 seems to be doing it?
