## Description

The valve is a simple element that drops buffers when the “drop” property is set to `TRUE` and lets then through otherwise.

Any downstream error received while the “drop” property is `TRUE` is ignored. So downstream element can be set to `GST_STATE_NULL` and removed, without using pad blocking.
