Description Marie Maurer 2018-05-18 15:27:42 UTC 
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?
