hello everyone, I encountered some issues while using GStreamer, and I currently suspect it might be related to drm-master permissions. However, I don’t know how to resolve this
first test:
sudo GST_DEBUG=3 gst-launch-1.0 videotestsrc ! kmssink connector-id=215 plane-id=128
result: success
second test:
sudo GST_DEBUG=3 gst-launch-1.0 videotestsrc ! kmssink connector-id=231 plane-id=144
result: success
third test:
sudo GST_DEBUG=3 gst-launch-1.0 videotestsrc ! tee name=t ! queue ! kmssink connector-id=215 plane-id=128 t. ! queue ! kmssink connector-id=231 plane-id=144
result: fail
So, how should I configure GStreamer to use two kmssink elements and output to two screens simultaneously?
