I’m trying to use alpha plugin with gst-launch.
following pipeline is from official page and I only changed sink part.
gst-launch-1.0 videotestsrc pattern=snow ! mixer.sink_0 \ videotestsrc pattern=smpte75 ! alpha method=green ! mixer.sink_1 \ videomixer name=mixer sink_0::zorder=0 sink_1::zorder=1 ! \ videoconvert ! video/x-raw,format=I420 ! xvimagesink
This code works fine on my host Linux machine (18.04LTS) with gstreamer 1.14.1.
But does not work on TX2 (1.8.3) and Xavier (1.14.1).
The result image should be smpte75 image which have snow pattern in the middle.
However, Jetson gives me an image with black region instead of snow pattern.
Can anyone run this pipeline successfully?
