How to save MP4 with gstreamer from two e-CAM130_CUXVR cameras?

Hi

I’m trying to get depth map with two e-CAM130_CUXVR cameras. But I couldn’t do that because I don’t know how to get images simultaneously from the two cameras with at least 15fps. As I know the camera supports frame synchronization with internal trigger clock.
Is there a way to save images simultaneously from two cameras with the form of MP4 in line with frame synchronization with “GStreamer”?

Thanks in advance!
