Hi,

I have compiled this library with the embedded mediasdk that comes with OpenVINO 2020.4 on Coffeelake based system(i7-9700).
FYI, I have experienced significant overhead for composition workload as I am getting only roughly 17fps from compositing 4x 4K 30fps videos.

export GST_GL_PLATFORM=egl
VIDEO=/home/test/test.mp4

gst-launch-1.0 glvideomixer -v name=m \

    sink_1::xpos=1280 sink_1::ypos=0 sink_1::width=1280 sink_1::height=720 \
    sink_2::xpos=0 sink_2::ypos=720 sink_2::width=1280 sink_2::height=720 \
    sink_3::xpos=1280 sink_3::ypos=720 sink_3::width=1280 sink_3::height=720 ! fpsdisplaysink video-sink=glimagesink sync=false text-overlay=false \

I have also tried the plugin with the latest Q3 2020 Media Stack + Media SDK and still encounters the same issue.
