I am dynamically adding and removing sources similar to the Runtime Source Add/Delete example here. The dynamic source add and removal works as expected, the Nvmultistreamtiler auto-sizes when a source is added, but it does not auto size when the source is removed. Instead, a black tile remains for the removed source. Is there any way to have the tiler down size (remove the black tile) when a source is removed?

NOTE: This is similar to the topic below, but I am hoping for an update since this was closed. Thanks!

Try to set nvmultistreamtiler’s property square-seq-grid to 1.

I tested using nvmultiurisrcbin with nvmultistreamtiler and setting square-seq-grid to 1 and it works as expected
