Subject: [PATCH v2 2/5] media: visl: Add a stable_output parameter
Date: Tue, 24 Oct 2023 15:09:47 -0400 [thread overview]
Message-ID: <20231024191027.305622-3-detlev.casanova@collabora.com> (raw)
In-Reply-To: <20231024191027.305622-1-detlev.casanova@collabora.com>
This parameter is used to ensure that for a given input, the output
frames are always identical so that it can be compared against
a reference in automatic tests.
Reviewed-by: Daniel Almeida <daniel.almeida@collabora.com>
