an [=active=] or [=inactive=] codec and/or a [=background=] codec.

An <dfn lt="active codec|active">active codec</dfn> is a codec that has
received a call to `encode()`, `decode()`, `configure()`, `flush()` or `reset()`
in the past `10 seconds`, or has called its `output()` callback in the past `10
seconds`. Addionally, {{VideoEncoder}}s are considered [=active=] if they are
making progress in encoding queued {{VideoFrame}}s.

NOTE: Encoding large {{VideoFrame}}s can take more than `10s` per frame. The
special case for {{VideoEncoder}}s ensures that they are not reclaimed if more
than `10 seconds` elapses between each `output()` callback.

NOTE: A reliable sign of the working queue's progress is a call to `output()`
callback.

An <dfn lt="inactive codec|inactive">inactive codec</dfn> is any codec that does
not meet the definition of an [=active codec=].
