Subject: [FFmpeg-devel] [PATCH 2/4] swscale/input: add support for P012
Date: Sun, 4 Sep 2022 22:14:28 -0700
Message-ID: <20220905051430.218289-3-philipl@overt.org> (raw)
In-Reply-To: <20220905051430.218289-1-philipl@overt.org>
As we now have three of these formats, I added macros to generate the
conversion functions.
