compositor

I hope you are doing well. I am currently encountering an issue while
working with the GStreamer 1.14 version of the compositor element within my
setup. My setup involves a 2x2 configuration, where I'm using four UDP
inputs and applying a compositor with a 2x2 tiling arrangement. The problem
arises when one of these input sources is missing. In such instances, the
compressed output stream functions as expected. However, the uncompressed
output stream does not appear to be generated. I'm uncertain whether this
problem is specifically tied to the compositor element or if there might be
another underlying cause. Your assistance in resolving this matter would be
highly appreciated.
