You are explaining nothing that was not already present in the commit
message, and my interpretation is still: you are engaged in a wrong
solution and are trying to make it work, i.e. XY problem
<https://en.wikipedia.org/wiki/XY_problem>.

Just force the timestamps to the input of framesync filters and you will
get what you want on the output.
