Subject: [PATCH v5 1/3] docs: ext-ctrls-codec: Document cyclic intra-refresh zero control value
Date: Tue, 22 Jun 2021 14:39:56 +0300	[thread overview]
Message-ID: <20210622113958.809173-2-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20210622113958.809173-1-stanimir.varbanov@linaro.org>

In all drivers _CYCLIC_INTRA_REFRESH_MB default control value is zero
which means that the macroblocks will not be intra-refreshed. Document
this _CYCLIC_INTRA_REFRESH_MB control behaviour in control description.
