You may try using overlaysink plugin, as described in section 7.5 (Overlaysink usage) of
“The overlaysink plugin is based on the GPU. It provides two main functions for video rendering:
• Video Overlay: composites multiple video playbacks into the same display.
• Multiple Display: shows videos to multiple displays, up to four displays.”
Please refer to section 18.104.22.168.3 (Multiple videos overlay) for example.
Also, please look at section 7.3.16 (Video composition).
