You can see two input video link to the same sink_0 of glvideomixerbin. This is abnormal. cmdline as below: gst-launch-1.0 glvideomixer background=2 name=m sink_1::xpos=200 sink_1::ypos=200 sink_2::xpos=400 sink_2::ypos=400 sink_2::alpha=0.5 ! glimagesink sync=false uridecodebin uri=file:///mnt/src/6Q_performance/big_buck_bunny_1080p_h264.mov ! m. uridecodebin uri=file:///mnt/src/6Q_performance/big_buck_bunny_1080p_h264.mov ! m. uridecodebin uri=file:///mnt/src/6Q_performance/big_buck_bunny_1080p_h264.mov ! m.
Any one can give some explanation?
Works for me, got sink_0/1/2 on my graph. Few questions: What version of Gst is this ? Can you share the .dot file ? Is your pipeline working ? This situation is not really possible (a pad won't let you link it twice). So I suspect a but in the generated .dot or something in these lines.

Yes， I have the .dot file. Correct the title to "glvideomixer: meet two output src pads linked to one sink pad"
