From f186d19313ffab22b0253a3fc3d569b67ddae859 Mon Sep 17 00:00:00 2001 From: Detlev Casanova Date: Mon, 2 Oct 2023 14:35:22 -0400 Subject: [PATCH 2/5] media: visl: Add a stable_output parameter 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.
