           Summary: cannot pass arguments to effects with ges-launch-1.0
    Classification: Platform
           Product: GStreamer

Hi,

I wanted to experiment with the videocrop effect from the command line and I do
not understand how to pass properties to an effect with ges-launch-1.0

>From the help text I get that something like the following should work:

ges-launch-1.0 +test-clip smpte s=0 d=2 set-alpha 0.5 +test-clip blink s=0 d=2
+effect "videocrop top=10"

but it does not, I get this error:

ERROR: Could not create timeline because: Unknown property in --effect: top

Also the "d" property seems to be a duplicate and the "e" property seems broken
too.

Any idea?

Thanks,
   Antonio
