Description

gst-launch-1.0.exe videotestsrc ! videoscale ! video/x-raw,width=1280,height=720 ! videocrop top=2 left=0 right=0 bottom=0 ! videoconvert ! d3dvideosink

This pipeline produce black screen on GStreamer 1.14.0 and 1.14.1 but works on v1.12.4 on two different computers.

Removing the videocrop by setting top=0 or changing d3dvideosink to glimagesink works, the problem seems to be the interaction between videocrop and d3dvideosink on GStreamer 1.14.x

Version: 1.14.1
